|

* This file contains the check_procs plugin

* Checks all processes and generates WARNING or CRITICAL states if the specified
|
||||
* metric is outside the required threshold ranges. The metric defaults to number
|
||||
* of processes. Search filters can be applied to limit the processes to check.
