IIRC, you can look at zIIP-eligible time (CPUZIETM). If it is a high value, you are not only losing the benefit of running on an additional uncapped specialty processor, you are potentially wasting money if then running on a GP at a time that drives the system to a new 4HRA on software costs!
I justified the purchase of zIIP solely on this basis when I was able to demonstrate a ROI in five months due to eliminating the potential increase in costs attributed to running on a GP during the setting of a new peak four hour rolling average. YMMV Props to Al Sherkow and his LCS software to be able to prove my assertions.

If a zIIP becomes heavier used, delays for the zIIP begin to show up. It is at 30% utilization when you have 1 zIIP, 60% utilization when you have 2 zIIP. It the zIIP becomes heavier loaded and delays are growing, the CP is asked to assist the zIIP. The is also reported in RMF.
