2.9.2 Usage Guidelines

The WLM Goal Mode Service inquiries are a series of reports
that provide an overview of how service is being delivered
and identify potential delays to service delivery.  These
reports let you quickly determine if service objectives are
being met during the reporting intervals chosen and perform a
first-level problem analysis when objectives are not being
met.

The reports are grouped according to usage:

o  WLM Service Definition Entries

   This is a detailed listing of the WLM Service Definitions
   that were in effect during the reporting interval. A good
   understanding of the service definitions is required to
   properly interpret the other reports. They can help
   explain why a particular service objective is not being
   met.

o  Analysis of Service Delivered, by WLM Classes

   These reports provide a summary of delivered service by
   SYSPLEX, and optionally by LPAR. The reports contain data
   on SRM-based transaction service, resources consumed, and
   delays. They can be ordered by WLM Service Class and
   Period, WLM Report Class, WLM Importance, or WLM Workload
   group.

o  Analysis of Service Delivered by LPAR

   These reports provide a summary of service by LPAR,
   including processor usage in times and MSUs, together with
   all of the workloads contributing to the LPAR busy. This
   helps you understand and quantify those workloads that are
   driving the LPAR consumption, so you can plan for use of
   the Defined Capacity Limit function required to implement
   the sub-capacity licensing feature.  The reports are
   ordered by LPAR. The workload information can be
   summarized by WLM Service Class, WLM Report Class, WLM
   Importance, or WLM Workload group.

All of the reports provide support for special purpose
processors. In addition to tabular reports, CSVs can be
optionally produced for subsequent use by Q&R to create
charts, graphs, and reports on the users' workstation.

The following sections discuss new performance metrics that
were added to the CA MICS Performance Manager in support of
the WLM Goal MOde Service queries.
