* Description:
-*
-* This plugin checks the number of currently running processes and
-* generates WARNING or CRITICAL states if the process count is outside
-* the specified threshold ranges. The process count can be filtered by
-* process owner, parent process PID, current state (e.g., 'Z'), or may
-* be the total number of running processes

+* 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.
