2.7.2.2 Storage Used by Workload Types-Bar Chart

GRAPHIC RESULTS

This graphic analysis provides a vertical bar chart of total
storage frames used by various defined workloads.

ANALYSIS GUIDELINES

Total storage includes both central and expanded frames.
This chart can help you understand what workloads are your
major consumers of storage frames.  It can also help you
determine if storage usage by a competing workload appears
correlated with a period when other measurements reported
during that same period were degraded.

You can analyze memory use further using the Real Storage
Management analysis reports described in Section 2.2. Virtual
storage allocation patterns can have an effect upon processor
storage usage.  These can be analyzed using the Virtual
Storage Management analysis reports found in Section 2.5.
Each of these chapters can help you understand and manage
memory use by particular workloads.

SPECIAL CONSIDERATIONS

If you do not provide a workload description, each
performance group or service class (for a system operating
in "goal mode") will be treated as a separate workload.  This
may provide so many unique categories that your analysis may
prove difficult.  You will probably find analysis and
reporting more meaningful if you describe workloads.
