I used to use SMF type70 records (PR/SM data) and compiled grafics (SAS, MXG) that show what each lpar used in each interval. Being 'flatlined' at the top of the box certainly showed that the machine was overloaded, despite the actual lpars still showing room. They could not get it because the physical processors were busy elsewhere. I had a separate grafic for ZIIPs, as they had a different 100% - they were much faster than our GCPs.
