A port of log4js to node.js
The logFaces appenders send JSON formatted log events to logFaces receivers. This appender uses HTTP to send the events (there is another logFaces appender that uses UDP). You will need to include axios in your dependencies to use this appender.
type
- logFaces-HTTP
url
- string
- logFaces receiver servlet URLapplication
- string
(optional, defaults to empty string) - used to identify your application’s logstimeout
- integer
(optional, defaults to 5000ms) - the timeout for the HTTP request.This appender will also pick up Logger context values from the events, and add them as p_
values in the logFaces event. See the example below for more details.
log4js.configure({
appenders: {
logfaces: { type: 'logFaces-HTTP', url: 'http://lfs-server/logs' }
},
categories: {
default: { appenders: [ 'logfaces' ], level: 'info' }
}
});
const logger = log4js.getLogger();
logger.addContext('requestId', '123');
logger.info('some interesting log message');
logger.error('something has gone wrong');
This example will result in two log events being sent to lfs-server
. Both events will have a p_requestId
property with a value of 123
.
