RE: % CPU Usage Monitoring

Hi

I am not sure if anybody answered on this question yet. I use the
following to pull the CPU information, if that will be of any help:

exec sql SELECT AVERAGE_CPU_UTILIZATION into :pCPUAVG
from TABLE(QSYS2.SYSTEM_STATUS('YES')) x;

Check the link for more info:
https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_74/rzajq/rzajqudf
sysstatus.htm

In the beginning I also struggled to compare the values with the
DSPSYSSTS, but I came to trust the values retrieved with this SQL.

Hope it helps.

Pieter

Subject: Reg: % CPU Usage Monitoring

Hi All,

I am trying to monitor the CPU usage maximum utilization and minimum
utilization when performing a process in iSeries. For this, i am storing
the SYSSTS details into an outfile for every 1 second using the API
QWCRSSTS - Format SSTS0200 - % processing unit used (Position from 33 to
36) as CPU usage.

Some times it seems to be correct when i compare the value manually by
checking the DSPSYSSTS command. But some time the API is providing the CPU
usage more than 80% but when i look into DSPSYSSTS it will still showing
CPU used only 20%.

Am i not looking into the right place for CPU usage?

Regards,
Surender K
