List of Plugins

The purpose of mcelog plugin is to send notifications and stats relevant to Machine Check Exceptions (MCE) when they occur. The plugin leverages the mcelog Linux utility to detect that an exception has occurred. mcelog supports a client server model and does the logging and accounting of exceptions when they occur. The plugin simply leverages the client protocol of mcelog to detect when an exception has occurred. The plugin does the following:

  • Checks mcelog server liveliness, reports a failure if it’s not running or if it fails.
  • Retrieve aggregated Memory Corrected and Uncorrected Errors from the client protocol (Submit event/stat).

Mcelog must be configured to run on the platform in daemon mode and logging capabilities must be enabled. For a full description of available options please refer to the collectd.conf(5) manual page.
