Incorrect CPU Util on AIX 5.3 SMT enabled

I have an AIX 5.3 machine that is SMT enabled.  According to Performance Assurance, the CPU Utilization is 100% but, the system admins say that it is only around 30-40%.

Does anyone have any thoughts on how to go about resolving the incorrect reporting in Analyze?

Since this is a Performance Assurance question, this thread will be moved to the BMC Developer Network > Service Assurance > Capacity Management > Capacity Planning community.

Re: Incorrect CPU Util on AIX 5.3 SMT enabled

Hi,

 

is it display the total of all your cpu utilization on AIX? or just display 100%.

Is it possible to patch the agent or upgrade it to 7.4.10 + patch? since the patch for perform is always updated by BMC.

but I think you need to try in development machine first

 

Regards,

Re: Incorrect CPU Util on AIX 5.3 SMT enabled

Hi, remember when you are working with BPA 7.X and you are trying to do a Capacity/Performance Analysis on AIX especially with SMT enabled let's say you are setting your Virtual CPU's to '2' therefore the logical cpu's will be 4, BPA especially before 7.4 it would think there would be 4 CPU's but you have set your lpar to 0.8 with 2 virtual cpus, therefore 4 logical cpu's big prob's because you would need to calculate manually, but i still would like to see some more help from bmc they really need to understand the new technology involved in AIX 5.X especially with AIX 6 now out.... we will see what happens .... hope this helps take care mike.
