I don't know about SMF and capping, but when our processor is capped we know about it big time. We have a z/10 P01 Uniprocessor and when capping kicks in it cuts our CPU busy in half and things come to a standstill. We use RMF III CPC reports to watch how close we are getting to being capped. We found some documentation on how to build a RMF III User report which has 'Time Until Capping'. We usually know capping is getting close because we have been running the processor close to or at 100% busy for some length of time before capping kicks in.

It's been about four years since we went from underpowered to having plenty and I was frying other fish. How can I determine from SMF when we were being capped by WLM. I have the cap set at 16 MSU. We are preparing to run some large conversions and the money people want some assurance that lifting the cap will help enough to justify the expense. I have MXG and still run the daily PDB stuff. I just haven't needed to look at it for some time.
