Does this mean cpu is almost fully occupied by the process?
This is running check_mk monitoring software on one of the SuSE enterprise linux 11 sp4. Recently, found that the system cpu utilization is always stay at higher level, and a "top" command shown that %us and %sy are still reasonable. However, a check_mk process -cmc always occupied 95+%. Does this means that cmc is always "preoccupied" with such as high percentage of CPU utilization?
Thanks in advance.

I would suggest that you post a text document in the future. Some people won't view someone else's Document. They can have Macros and bugs that can be used to infect a system.
cmc is using nearly all of 1 cpu and 2.5G of your 16G ram. If you think this is abnormal, you might want to investigate. %sy is relatively high, so I would suggest lsof & iotop as an investigative starting point.

Hi Noci,
To clarify, this is a vm, with 1 virtual processor.

You mean cmc is a VM? I would run top inside that VM to see what it's doing then.

Hi Duncan,
I mean this is a SuSE Linux VM.

To be clear: the snapshot of top is not from inside the VM, right?

Hi Duncan,
No, top is typed inside the vm.

You can try to check if
strace -p cmcpid
or
ltrace -p cmcpid
show where it is busy with.... (you can stop strace/ltrace with ctrl-c).
if both show nothing then the program is looping without calling any systemservice or library calls.
