The RMFMCL query shows the average MSU usage of LPARs at the RMF interval level. All LPARs are accounted for with the exception of LPARs that exclusively use 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, a chart is produced. The query generates two separate data extracts. One for LPARs that have defined capacity limits, and the other for LPARs with no defined capacity limits. One of the uncapped LPARs for each CPC is the ‘PHYSICAL’ LPAR that captures PR/SM overhead.
The top example shows the average MSU usage chart for an LPAR (PRSMLPNM=’CA31’) running on an IBM z10 2097-712 CPC. The RMF intervals records were generated at 15-minute intervals and the LPAR has a defined capacity limit of 455 MSUs. The second example shows the average MSU usage chart for another LPAR (PRSMLPNM=’CA13’) on the same CPC. The RMF intervals records were also generated at 15-minute intervals. This second LPAR has no defined capacity limit.
