Overview

The RMFEHH query shows the peak hour of dispatch, over the past 32 days, for each engine type (CP, zIIP, zAAP, IFL, ICF) in the shared LPAR engine pools. The query generates two dispatch charts for each engine type in each Central Processing Complex (CPC).

The example shows the two charts generated for the shared CP engine pool of an IBM z10 2097-712 CPC. The top chart shows the peak hour, per day percent utilization of the CP engine pool, with the breakdown of the various LPARs that use CP engines. The second chart shows the same information, minus the LPAR breakdown. The chart includes a reference line (right Y-axis) that shows the number of engines in the CP engine pool (12 engines in this example). The X-axis shows the date concatenated to the high use hour. In the example, the first vertical bar shows that the peak CP engine dispatch occurred on August 29th, 2010 (a Sunday) during hour 23: "2010-08-29-23"—when the utilization of the CP engine pool was about 43 percent.

A similar set of charts is created for each engine type, one where the vertical bars show individual LPAR percent utilization, and the other showing percent utilization plus the physical engine count for the engine type.
