lager

lager plugin

Description

The lager plugin subscribes to the lager application running on the managed node and is capable of reporting all the notifications/logs generated by it to WombatOAM. By default, it starts itself reporting at the warning level; this can be changed using the options shown on the WombatOAM dashboard.

Applications it depends on

lager

Modules

wombat_plugin_lager and wombat_plugin_lager_handler

Reports

The plugin reports logs/notifications and the following metrics to WombatOAM in the "Lager notifications" category:

• Lager debug events Tags: dev

• Lager info events Tags: dev

• Lager notice events Tags: dev

• Lager warning events Tags: dev, op

• Lager error events Tags: dev, op

• Lager critical events Tags: dev, op

• Lager alert events Tags: dev, op

• Lager emergency events Tags: dev, op

These metrics show the number of log entries captured by WombatOAM on different log levels. Note that WombatOAM collects log entries on warning level and above by default, so the value of the debug, info and notice metrics will be zero. (Unless this default log level is set to a lower value.)

Configuration options

• report_metrics (boolean, default: true): Specifies whether the WombatOAM server should receive the values for the above mentioned metrics.

Example wombat.config entry

{set, wo_plugins, plugins, lager, report_metrics, true}.
