Re: [ITM62] Internal CPU Utilization Situations

Most questions like this end up as PMRs,  In that case L3 references the 
logic and sometimes works with development to provide an exact answer.

If the comparison is against something like topas L3 can usually give a 
complete answer. If it is another product, usually the other company also 
needs to get involved to compare logics.

I do know that as of ITM 630, the CPU measurement logic was changed 
significantly to increase accuracy. Don't know details... sorry.

Hi List,
I want to elaborate the scenario.
As per SLA if CPU utilization is more than 70% for a sustained period of 
15 mintues then it is a breach. So which CPU attribute will help me to 
acheive this? Can anyone guide me on this?
 
Agent OS -- AIX
ITM -- 6.2.3 FP3
Report -- custom cognos report 
 
Regards
Sebastian

Thanks Jared.
 
I'm using 6.23 FP3 and have to generate CPU reports for SLA (>70%). CPU 
Busy (percent) is breaching most of the times and we did a comparison with 
optim . Optim shows 40% when CPU Busy is 70% in ITM. So I want to know for 
SLA reports which attribute is best? What is the purpose of following 
attributes?
 
Avg CPU Busy 5
CPU Usage
 
Regards
Sebastian

I find that on AIX, it is best to use either the AIX Premium agent, or 
Unix OS Agent 6.2.3 FP2+ and monitoring Entitlement metrics, over standard 
Unix CPU metrics.  We have situations that monitor the Entitlement Used 
Pct, and Phys Busy Pct attributes of the AIX Premium agent. 

The AIX metrics were introduced into the Unix OS Agent at 6.2.3 FP1, but I 
found too many issues at that level, and wouldn't recommend it.

Hi,
 
I'm facing almost same issues in CPU utilization (AIX ). Which is the 
correct attrribute to analyze CPU utilization?
Polling interval is 5 mints and  I used CPU Busy (percent) attribute. But 
when I compare with optim / topaz reports,  ITM is showing higher values 
(almost double).
There are multiple attributes available with the agent. Which one to use , 
I'm confused . Can anyone help me? 
 
Avg CPU Busy 1
Avg CPU Busy 5
Avg CPU Busy 15
CPU Busy (Percent)
CPU Usage

I am running ITM 6.2 FP2 using some of the built-in CPU situations for the 
SMP CPU attribute group on AIX boxes.  When I go to the System Information 
and System Details screen in TEPS, CPU ultization does not always seem to 
reflect the same things that the sar command and topas command show when 
they are run on the same box.  The internal CPU Situation using the 
Average CPU Busy Attribute Item also occasionally fires when other 
indicators on the box do not reflect high CPU utilization. 
 
Has anyone else noticed this?
Does anyone know the behind the scenes commands used by TEPS to determine 
CPU utilization?
 
Thanks.
