Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.6.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:55680\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.6.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:55680\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

chat][gitter-image]][gitter-url]\n[![NPM Published Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.6.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:55680\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.6.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:55680\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3.

chat][gitter-image]][gitter-url]\n[![NPM Published Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.6.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:55680\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55680\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1.

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1.

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '' // url is optional and can be omitted - default is localhost:4317\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n )\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nTo see how to generate credentials, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('grpc');\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:4317\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n url: '', // url is optional and can be omitted - default is localhost:55681\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst meter = new MeterProvider({\n exporter,\n interval: 60000,\n}).getMeter('example-meter');\n\n// Now, start recording data\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.16.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/trace`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n serviceName: 'basic-service',\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used.

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used.

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is localhost:4317\n url: ':',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

Version][npm-img]][npm-url]\n[![dependencies][dependencies-image]][dependencies-url]\n[![devDependencies][devDependencies-image]][devDependencies-url]\n[![Apache License][license-image]][license-image]\n\nThis module provides exporter for web and node to be used with [opentelemetry-collector][opentelemetry-collector-url] - last tested with version **0.25.0**.\n\n## Installation\n\n```bash\nnpm install --save @opentelemetry/exporter-collector-grpc\n```\n\n## Service Name\n\nThe OpenTelemetry Collector Exporter does not have a service name configuration.\nIn order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name].\n\n## Traces in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/traces`.\n\n```js\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nBy default, plaintext connection is used. In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/tracing');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/metrics');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or

In order to use TLS in Node.js, provide `credentials` option like so:\n\n```js\nconst fs = require('fs');\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n credentials: grpc.credentials.createSsl(),\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nTo use mutual authentication, pass to the `createSsl()` constructor:\n\n```js\n credentials: grpc.credentials.createSsl(\n fs.readFileSync('./ca.crt'),\n fs.readFileSync('./client.key'),\n fs.readFileSync('./client.crt')\n ),\n```\n\nTo generate credentials for mutual authentication, you can refer to the script used to generate certificates for tests [here](./test/certs/regenerate.sh)\n\nThe exporter can be configured to send custom metadata with each request as in the example below:\n\n```js\nconst grpc = require('@grpc/grpc-js');\n\nconst { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');\nconst { CollectorTraceExporter } = require('@opentelemetry/exporter-collector-grpc');\n\nconst metadata = new grpc.Metadata();\n// For instance, an API key or access token might go here.\nmetadata.set('k', 'v');\n\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n metadata, // // an optional grpc.Metadata object to be sent with each request\n};\n\nconst provider = new BasicTracerProvider();\nconst exporter = new CollectorTraceExporter(collectorOptions);\nprovider.addSpanProcessor(new SimpleSpanProcessor(exporter));\n\nprovider.register();\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n```\n\nNote, that this will only work if TLS is also configured on the server.\n\n## Metrics in Node - GRPC\n\nThe CollectorTraceExporter in Node expects the URL to only be the hostname. It will not work with `/v1/metrics`. All options that work with trace also work with metrics.\n\n```js\nconst { MeterProvider } = require('@opentelemetry/sdk-metrics-base');\nconst { CollectorMetricExporter } = require('@opentelemetry/exporter-collector-grpc');\nconst collectorOptions = {\n // url is optional and can be omitted - default is grpc://localhost:4317\n url: 'grpc://:',\n};\nconst exporter = new CollectorMetricExporter(collectorOptions);\n\n// Register the exporter\nconst provider = new MeterProvider({\n exporter,\n interval: 60000,\n})\n['SIGINT', 'SIGTERM'].forEach(signal => {\n process.on(signal, () => provider.shutdown().catch(console.error));\n});\n\n// Now, start recording data\nconst meter = provider.getMeter('example-meter');\nconst counter = meter.createCounter('metric_name');\ncounter.add(10, { 'key': 'value' });\n```\n\n## Running opentelemetry-collector locally to see the traces\n\n1. Go to examples/collector-exporter-node\n2. run `npm run docker:start`\n3. Open page at `http://localhost:9411/zipkin/` to observe the traces\n\n## Useful links\n\n- For more information on OpenTelemetry, visit: \n- For more about OpenTelemetry JavaScript: \n- For help or
