MSSQL Server: Page Life Expectancy (PLE)

Distribution	Official part of Checkmk
License	GPLv2
Supported Agents	Windows

This check monitors the page life expectancy on MSSQL Server. It is possible to configure lower thresholds for PLE using the ruleset "MSSQL Page Life Expectancy". By default, the check returns a WARN state if the PLE falls below 350 seconds, and a CRIT state if it falls below 300 seconds.

The prerequisite for this check is that the mssql.vbs agent plugin is installed on the host. Please refer to the online documentation for installation instructions.

Item

The MSSQL object and instance name (as defined in the view "sys.dm_os_performance_counters"), separated by a space. If no instance name is defined by MSSQL, the object name is used on its own.

Discovery

One service is created for each available PLE counter.
