2.1.1 Functional Description

ILM analysis inquiries let you analyze the following items:

o The MSU consumption rates of z/OS workloads

o WLM's soft capping activity

o Defined Group Capacity MSU consumption

o The estimated MSU consumption of non-z/OS workloads

The graph produced when analyzing z/OS workloads plots MSU
consumption rate, MSU four-hour rolling average, and the
defined capacity for each PR/SM controlled LP present in the
data.  When defined group capacity analysis is specified two
additional reports are generated, separately charting the
summarized MSU consumption rate and four-hour rolling average
of each capacity group.

The report produced when analyzing z/OS workloads contains
the same metrics displayed in the graph with the addition of
a soft-capping percentage for the LP and a threshold
indicator. This field will indicate if the soft-capping
percentage exceeded the user-specified soft-capping
threshold.

You also have the option to activate threshold alerting. This
produces a ServicePlus Service Desk alert when the
soft-capping threshold has been exceeded.

For more information on using the ServicePlus Service Desk
alert facility, see section 4.9 of the CA MICS Resource
Management Planning, Installation, Operation, and Maintenance
Guide.

MSU consumption rate analysis of non-z/OS workloads at the
DETAIL timespan calculates the MSU consumption rate and the
MSU four-hour rolling average of the non-z/OS workload as if
the same workload were running under z/OS.  At higher
timespans, the ability to calculate the MSU four-hour rolling
average is lost; therefore, these elements are dropped from
the report.

The ILM analysis queries use data from the CPU Activity
File (HARCPU). The range of data that can be reported from a
particular CA MICS database depends on the timespans that
were defined for this file and the number of cycles defined
in each timespan. If you are not familiar with the generation
options for the database unit containing the MVS HAR
Information Area, contact your CA MICS administrator for
assistance.
