Contents

This section provides an overview of the Intel® Manager for Lustre* software GUI. For a complete description of the GUI, see Graphical User Interface.

The Intel® Manager for Lustre* software GUI presents a set of intuitive windows that let you set up, configure, monitor, and manage Lustre* file systems. The menu bar provides access to these capabilities. Click the following links for overview information:

• | Menu bar

• | Dashboard window

• | Summary of charts

• | Configuration menu

• | Jobs Stats

• | Logs window

• | Help

• | Status Indicator and window

• | Alert bar

## Menu bar

Following is the top menu bar. From here you can access the entire GUI, view the collective Status of all file systems and devices, and also access Help.

## Dashboard window

The Dashboard displays a set of charts that provide usage and performance data at several levels in the file systems being monitored. At the top level, this window displays an aggregate view of all file systems. You can select to view and monitor individual file systems and servers at the Dashboard. To view a single file system, click Configure Dashboard and under File System, select the desired file system.

The following is a partial view of the Dashboard.

## Summary of charts

The Dashboard window presents several charts that display rich visual information about the current and historical performance of each Lustre file system. Following is an example of the Read/Write Heat Map, which is a color-coded map revealing the level of read/write activity per OST, over time.

The following twelve charts are presented. For more information, see View charts on the Dashboard.

• | Read/Write Heat Map chart

• | OST Balance chart

• | Metadata Operations chart

• | Read/Write Bandwidth chart

• | Metadata Servers chart

• | Object Storage Servers chart

• | CPU Usage chart

• | Memory Usage chart

• | Space Usage chart

• | File Usage chart

• | Object Usage chart

## Configuration menu

The Configuration drop-down menu provides access to the following several windows, where you can create, configure, and manage file systems:

• | Servers - This window lets you add servers to the storage system and configure LNet for each server, provides server status information, and lets you start, stop, and remove servers. From here you can also automatically configure Corosync for managed HA servers.

• | Power Control - This window lets you configure power control for each server. Here, you can add baseboard management controllers to configure IPMI to support server failover and also assign PDU outlets.

• | File Systems - This window lists your current file systems and provides current configuration information. This window also provides access to step-by-step procedures to create and configure a file system and add system components. From this window, you can start, stop, or remove an entire file system, and you can start, stop, or remove management, metadata, or object storage targets.

• | HSM - Hierarchical Storage Management. This window displays HSM information for one or all Lustre file systems for which HSM has been configured. After configuration, the HSM Copytool chart displays a moving time-line of waiting copytool requests, current copytool operations, and the number of idle copytool workers.

• | Storage - This window lets you configure and view a custom storage system appliance provided by a storage solution provider. The features on this window are specific to the appliance provided by the storage solution provider.

• | Users - This window lets you configure accounts for superusers and users.

•

Volumes - This window provides features to configure primary and failover servers in file systems with servers configured for high availability. Each Lustre target corresponds to a single volume. If servers in the volume have been physically connected and then configured for high availability (using this Volumes window and the Power Control window), then primary and failover servers can be designated for a Lustre target. Only volumes that are not already in use as Lustre targets on local file systems are shown. A volume may be accessible on one or more servers via different device nodes, and it may be accessible via multiple device nodes on the same host.

• | MGTs - This window provides features to create and configure a management target.

## Job stats

Clicking the Jobstats button on the top menu bar lists the top ten jobs currently in process. The listed jobs can be sorted by column and average duration can be selected. Column sorts and duration will be persistent when navigating away and back to the page.

Note: Job stats need to be enabled before then can be viewed. See View Job stats.

## Logs window

The Logs window displays log information and lets you filter events by date range, host, service, and messages from Lustre or all sources. The logs window also features querying with auto-complete and linkable host names.

## Help

Help is context-sensitive; Clicking Help at the menu bar opens this Online Help to the related topic. Internet access is not required.

## Status Indicator and window

The Status indicator provides information about the functioning and health of each file system. Alerts are messages that indicate that the file system may be, or is, operating in a degraded mode.

• | A green light indicates that all is normal. Note that a green light does not indicate anything about file system performance.

• | A yellow light indicates that one or more warning alerts have been received. The file system may be operating in a degraded mode, for example a target has failed over, so performance may be degraded.

• | A red light indicates that one or more errors alerts have been received. This file system may be down or is severely degraded.

The Status window displays information alerts, commands that are executing, and events. For more information, see Status window.

## Alert Bar

This red bar briefly appears if there are any active error or warning alerts on your system. Clicking Details opens the Status window and reveals the current, active alerts.
