LPAR level charts

The LPAR level charts use standard HARLPC file data elements to derive the dispatch variables:

Left Y-axis

ENGDISPT – Total CP Engine Dispatch (Set to LPCTODTM – Total CP Processors Dispatch Time / 3600)

ENGDISPE – Effective CP Engine Dispatch (Set to LPCTOEDT – Total CP Proc. Effective Dispatch Time / 3600)

The vertical bars, for the LPAR level charts, show the total and effective dispatch of the logical CP processors assigned to the LPAR. The total and effective dispatch times are divided by 3600 to convert from seconds of dispatch to hours of dispatch. Because one engine can be dispatched a maximum of one hour, per hour, this conversion allows the dispatch of the engine pool to be represented as logical engine dispatch hour equivalents. For example, three logical CP engines could, at full utilization, provide three hours of dispatch time in one hour.

Right Y-axis

LPCAVCPU - Avg Number of Active CP Processors

This horizontal reference line, for the LPAR level charts, show the average number of logical CP processors assigned to the LPAR. The actual dispatch engine equivalents, charted with the vertical bars, can reach, but should never exceed this line. IBM features like the Intelligent Resource Director (IRD) can activate and deactivate logical processors at the LPAR level—so this line may not reflect a constant value over the entire day.
