From the looks of it you've a really loaded system, your memory is nearly exhausted. And you're CPU is heavily loaded.

What are you running on this server?

Re: Problem Performance

Steven E. Protter — Tue, 09 Nov 2004 10:56:07 GMT

swapinfo -tam

vmstat 1 30

Are we paging.

More advanced perf data collection attached.

If you are paging into swap, its memory buy time.

The good news is you don't seem to be waiting on disk io. That may be because there is too much stuff running on the box to have time to do a lot of disk io

Answering Nelson's question can give us all information that can be useful in giving you further assistance.

For paging:

vmstat -S 5 20

Look at SI and SO columns...

Rule of thumb for performance - Check Memory first, then disk, then CPU...

Your disks and CPU may be loaded because of memory pressure - fix the memory - and your CPU and disks may be fine.

Decrease the size of your buffer cache may help - what is it set to? DBC_MAX_PCT and DBC_MIN_PCT...

More memory may be your solution...

Hi Jairo,

Openview tools can be both memory and CPU extensive. I suggest you buy little bit more memory and some CPUs. Try installing latest Openview/NNM patches to see if they make any difference. More nodes/CIs you add and more maps you add/create, more will be memory and CPU usages.

This time we can't really ask you to go back to your developers. Can we? ;-). Openview is HP's tool. Even before installing Networker, you system looked busy. Stop running some unnecessary processes such as sendmail, prm, httpd etc., if you don't need them.
