Comparing st06 cpu utilization with TF_CPU_ALL cpu utilization entries

[Former Member]

Hi All,

Need your inputs on the following senario.

I have a jco program that invokes FILL_SNAPSHOT_DATA to read data from TF_CPU_ALL.

Is it valid to compare st06 24 hours data with the data from TF_CPU_ALL.

I read that st06 transaction gets it data from SAPOSCOL.

Not sure if the source for SAPOSCOL and TF_CPU_ALL is the same.

The data does not match, that is the problem.

Thanks

Hello,

In ST06, you see what percentage of a single CPU is being

used by each process. Therefore, in your case, for SAPOSCOL you see

values as high for a single CPU. While your system has

multiple CPUs and the top command at the OS level is showing you the

overview of the whole system and what percentage of all CPUs does each

process consumes.

The os values are more accurate in terms of performance.

TF_CPU_ALL would be more accurate

Hi John,

Thanks for confirming the details.

I also came across SAP Note 431495 which states "Hourly values for ST06 history are incorrect". I am not sure if this is still valid as it is dated 2003.

Thanks
