Previous Topic: RMFMSU – Daily CPC MSU Use with Stacked LPARsNext Topic: Uses


Overview

The RMFMSU query shows the average MSU usage for the Central Processing Complex (CPC) at an hourly or RMF interval level, with the individual LPAR usage broken out in each vertical bar. All LPAR MSU usage is accounted for with the exception of LPARs that have only specialty engines, such as Coupling Facility LPARs with ICF engines only or Linux LPARs with IFL engines only. If an LPAR uses at least one general-purpose CP engine, it contributes to the chart. Two MSU utilization data extracts are provided One extract generates daily charts for each CPC, and another extract generates a single chart for each CPC showing multiple days of activity if multiple HARLPC file cycles are input.

The example shows the daily chart for an IBM z10 2097-712 CPC, with the average MSU usage for each 15-minute RMF interval,
