The RMF CPU report should show this information (for each CEC) both at the 
aggregate level and broken out by LPAR.

You might also look at the RMF Spreadsheet Reporter. More info here :
http://www-03.ibm.com/systems/z/os/zos/features/rmf/ 
and
http://publibz.boulder.ibm.com/epubs/pdf/erb2ug01.pdf

One way to "aggregate" multiple CECs is to total all processors and "normalize" 
to 100% for the "manglers"

It is part of my duties to show to management z/OS performance daily and 
monthly based on SMF RMF records.

CPU% utilization averages, memory usage, MSU, I/O rates, transaction rates, 
etc. are usually easy to present and explain. You get Averages, 90th 
percentile, absolute maximum/minimum, etc. as measurement criterias.

My problem is: I wish to show that our machines are heavily loaded or maximum 
loaded. 

My problem is that the different LPARs have their absolute maximum CPU% 
utilization at different hourly and 30 minute intervals. So LPAR 1 has 100% CPU 
utilization at 09:00, but LPAR 2 has 95% CPU utilization at say 13:00. If I 
combine these values for the day, they're sometimes over 100% which is 
undesirable or difficult to explain.

Sometimes I see those max CPU% drifts very far far away from the usual average 
CPU% utilization on one or more LPARs at a given interval, but not always at 
the same time.

Question: how do you performance guys and gals present those maximums? Or how 
do you prove that machines are heavily used? Do you use averages of those 
maximum CPU% utilization or what do you use? Do you combine all the LPARs and 
then work out the max? Any trending or statistical analysis methods to consider?

I'm using RMF and a commercial product (no SAS) to process those SMF RMF 
records daily and monthly. z/OS v1.13.
