MSSQL Server: Page Life Expectancy (PLE)
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
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.
One service is created for each available PLE counter.
