CPU usage in top

Lorenzo Facello — Fri, 13 Jun 2003 05:59:32 GMT

Hi All,
when I view top, some processes use a large part of cpu(130%-140%), but I try to verify at the same time with Glance and this processes were normally up with a acceptable cpu usage.
So, It's possible that top "lie".
I hope in yours suggestions.
Thanks.

Hello!

Does your top really write 130-140%
or that's what you understand.
You have few CPUs or one?
If only one you will be probably need to
patch you top.

You can try comparing the CPU usage using Glance.

make sure you have the latest top cumulative patch installed.

like for hpux11.0

Dont use the WCPU line in top (weighted cpu) - use the CPU line - which cant go over 100%.

Also, you may need a top patch;

PHCO_25204 1.0 top(1) cumulative patch.

This is the 11i version, probably a slightly different number for 11.0

Hi,
if you are using the version 11.11 of HPUX is probably known problem.

Try getting the latest top pathes.

HTH,
