[checkproc cpuabove]
requires=1.48
inihelp=<<EOT
Check for processes using more than a specified CPU utilisation. To make this work as intended you need to specify some
warning/critical criteria eg -w 50 for warning when a process uses more than 50% CPU. You probably also want to remove 
all processes with low CPU from the results. Do this using something like -exc _AvgCPU=@0:5 (which will exclude processes that have CPU utilisation between 0 and 5%)
ARG1  The processname to look for. Use % for wildcards.
   The process name typically only includes the actual file name minus its suffix eg firefox, svchost
   If there are multiple instances eg svchost, then some versions of Windows have them named all the same while others
   such as Windows 2008 Server, have them numbered eg svchost#1, svchost#2, svchost#3. To get all svchost processes you
   need to set ARG1 to svchost%
   To view all processes set ARG1 to "%" and the full process list will be included in the plugin output.

Note:  Use --nodatamode and/or NODATAEXIT settings to control what happens if no matching process is found.
