The RMFZAC query charts the hourly actual zAAP engine use, and zAAP engine eligible use for both the Central Processing Complex (CPC) and the z/OS LPARs using the shared engine pools of a CPC. Only PR/SM managed z/OS LPARs are charted. Non-z/OS LPARs and z/OS LPARs managed by VM are excluded from analysis because the data containing zAAP engine demand is not available.
The example shows the CPC level chart (top) for an IBM z10 2097-712 CPC, and one of the individual LPAR charts for an LPAR defined to that CPC.
The CPC level chart shows total zAAP engine demand, with the actual use and eligible demand stacked. The horizontal reference line in the CPC level chart shows the number of physical zAAP engines in the CPC shared engine pool.
The LPAR level chart shows zAAP engine use and zAAP engine demand as separate vertical bars for each hour of the day. The horizontal reference line in the LPAR level chart shows the number of logical zAAP engines assigned to the LPAR. One LPAR level chart is produced for each LPAR that executed zAAP eligible work.
