check_proc --metric=CPU - alternatives?

[Sebastian Ries]

Hi

I have the following Problem:

We have some Processes which are running but are idle for some time
(maybe some weeks) and the get used by a user.
While a single Process is used is should have a cpu usage varying
between 10 and 50%.
We have the problem that sometimes a process gets stuck and then is
running at 100% cpu usage.
=> this is what we want to check via Nagios.

I tried to use check_procs like:
./check_procs -w 80 -c 90 --metric=CPU --command=qemu-system-x86
but this did noch catch the processes.

After some testing and searching on the internet I found out that this
is depending on how ps calculates the cpu usage:
It devides the cputime by the runtime of the process, giving the average
cup usage over the whole process time -> which does not really help :-(

Does anyone know of an alternative check which gives me the cpu usage
actual of a process (or maybe the average over the last minute)?

Regards
Sebastian Ries
