hpvmapp using high % cpu

[Neville Lawrence]

We have a vmhost and two of the cpu's are being maxed out by hpvmapp. When doing a top the %WCPU is 197.69 and %CPU is 198.22. The other hpvmapp processes on that server are running at less than 10%. Is this normal and what is the best course of action to resolve this?

Thanks

Hi Neville,

Check it using
#sar -u 3 5
the above command will show the sar output 5 times in three second

If the high percentage is consistent, then it is not normal. You have to monitor the system and get some metrics.

sar â Mu 5 30
sar â q 5 30

Check with vmstat/top/glance also.

Also find out the 10 cpu users with PIDs (to see any unusual processes):
UNIX95= ps -e -o pcpu -o ruser -o args -o pid|sort -nr|grep -v %CPU|head -10

Regards.

Use glance and perf to get a usage summary report.

well I would first ask, what version of Integrity Virtual Machines you have.
Also, how are the VM's configured? And what are the VM OS's doing? have you looked on each VM OS to check what IT thinks is going on? i.e. are the VM OS's busy doing something heavy, ?
Use sar/top/glance on the Guest OS if it is HP-UX to see what the VM is doing.

Thanks for the replies. I have worked out what VM server is causing the issues. When doing a top, it appears that vxfsd is the process that is using the majority of the cpu, with little else going on. I have also checked on the other VM servers and they all appear to be ok, with vxfsd hardly using anty cpu usage. They are all running the same version of o/s 11.23.
