How to measure waiting time in run queue?

Hello guys,

I am doing a performance analysis on one of our psystem. Most of time I am using Nmon analyser to do my trend graph. But I can't find any help with it. We are interesting in the time spend by tasks in Aix run queue.

After looking the Aix documentation, I am pessimist to find any straight metric in order to measure that time.

So I need your help Smilie

Regards

Tech infos : Aix 6.1.6 on Power7
