Check manual page of ps.perf
August 29. 2015
State and Count of Processes (with additional performance data)
Supported Agents: Linux
Distribution: official part of Check_MK
This check does exactly the same as ps, but in addition
outputs performance data. Please refer to the manpage of ps for more details.
Note: If you want to use ps.perf on Windows systems then you need to install
the plugin psperf.bat into the plugins directory of you Windows agent.
Do not use wmicchecks.bat. This is obsolete.
In all cases the number of matching running processes found on the target
system is sent. If the agent supports it, also the virtual prozess size (VSZ)
and the resident size (RSS) in kB is send as well as the percentage of CPU
used by the matching processes.
If more than one process is matching, the values are added. The actual memory
usage of all processes together might be significantly smaller than the computed
size since they might (and most propably do) share memory.
ps.perf supports inventory in exactly the same way as ps, just
that the variable inventory_processes_perf is used instead of
