ES47 - strange cpu usage

[BG Jeong]

Hi all.
Our system is ES47.
When I monitor system resource using vmstat,
sys part is so high.

Do anyone know this case?

I'll attach a log file.

Thanks in advance.

Can you please post output of top and see which process is taking most of CPU.

What do you mean by "sys" part in the output?

[Vladimir Fabecic]

Hello BG
Can you supply more informations, such as what kind of application is this machine used for, is this machine in cluster, how many RAM do have, any swapping.
Looks like you may have heavy I/O utilization.

[Ivan Ferreira]

The system is not paging so the high sys is not caused by this activiy.

Use collect to identify the top processes and the disk activity, is this a stand alone host or part of a cluster?

This could be caused by a poor written application.

[BG Jeong]

sorry lately appling.

ES47 + smartarray 5402a
2 internal disk mirror
Oracle and Java base web appliction

Top monitoring output just display cpu%.
it's ok.

attach top and collect outputs.

That seems wrong.
No obvious user task to tie the system time to.
Has it always been like this?
When did you first notice?
What changed?
The system has only been runing for a month, but if it was mine, then I would first take a 'therapeutic reboot' and see if the problem goes away, only to start worrying if it comes back again.

If I wanted to know what was going on, then I'd go aske the kernel where it is spending its time. Use kprofile or dcpi.

Just 2 cpus, one in each RAD huh?
8GB is not much, but enough it seems.

Whuich Unix version.
Recent hardware suggest 5.1B-x

7 LAN's huh?
My guess at this time is that the network has a configuration error.
Maybe TCP, but more likely sysconfigtab : inet or maybe ipc.


hth,
Hein.
