Note
This applies only to the process class optional reports: SYSTEM, SERVER,
SUBSYSTEM, TRANSIENT, PATHWAY, and OTHER. The rest of the optional reports
are described in Section 4: Using GPA Information
.
When you specify the summary option, you receive the Process Distribution Analysis
for the class. When you specify the detail option, you receive all five sections. The
optional report enables you to perform several more detailed analyses than the
standard report does. With it you can:
• Identify programs or process names within a class that are consuming the
most resources.
• See how programs or process names within a class are distributed among the
processors in the system.
• Analyze programs or process names within a class in terms of their
processing profile, which includes: CPU utilization, queue length, messages
sent, and messages received.
GPA Standard Report
The following information describes in detail each of the entries in each of the sections
of the GPA Standard Report.

report section that are discussed below are identified in the text by numbers in
parentheses and by corresponding boldface numbers in the figures.

four subsections:

The purpose and contents of each of these subsections follow.
