CA MICS Hardware and SCP Analyzer (RMF) Queries › WLM Service Class and Report Class Analysis › RMFRPT – z/OS Report Class Analysis by SYSPLEX, CPCID, and SYSID › Overview

Overview

The RMFRPT query displays resource usage, performance indicators, summary sampled state percentages, and detailed execution delay state information for each Workload Manager (WLM) Report Class or Report Class Period. This information is provided by the following three data extract CSV’s at the z/OS LPAR (SYSID), Central Processing Complex (CPC), and SYSPLEX levels:

• Report Class by SYSPLEX
• Report Class by SYSPLEX CPCUID
• Report Class by SYSPLEX CPCUID SYSID

Each data extract generates the following four chart views:

1. CPU and PI
2. Sampling Summary
3. Exec Delay States Group 1
4. Exec Delay States Group 2

Refer to the RMFSRV – z/OS Service Class Analysis by SYSPLEX, CPCID, and SYSID query description for information about each of these chart views. The chart views and individual chart content for the RMFSRV and this RMFRPT queries are almost identical. The only difference is in the title area and relates to the type of the charted Report Classes.

WLM Report Classes can be homogeneous or heterogeneous. Homogeneous Report Classes are defined to include workloads from a single Service Class. Heterogeneous Report Classes are defined to include workloads that span two or more Service Classes.

For both homogeneous and heterogeneous Report Classes, the title area of each chart shows the SYSPLEX name, Report Class Name, Relative Importance, Goal Type, and Report Class period charted. For homogeneous Report Classes, all of these fields will be populated.

For heterogeneous Report Classes, the Relative Importance and Goal Type values will be blank and the Report Class Period value will show a value of 1 (one). This is because heterogeneous Report Classes include workload information drawn from multiple Service Classes that could have different importance levels, goal types, and periods.

Both chart samples shown previously are charts generated from the data extract Report Class by SYSPLEX CPCUID.

The first chart shows an example of a homogeneous Report Class, Report Class RCHORJBO. As you can see, all values in the chart title area are populated.

The second chart sample above shows an example of a heterogeneous Report Class, Report Class DISCRET. You can see that the Relative Importance and Goal Type are blank, the period reported is 1, and the Performance Index is missing.
