GPA Standard Report
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.
Example 3-1
through Example 3-15 show the sections of a typical report. The items
within each report section that are discussed below are identified in the text by numbers
in parentheses and by corresponding boldface numbers in the figures.
System Performance Summary
The System Performance Summary, as the name implies, is a concise presentation of
data designed to show quickly the overall system performance and to indicate the
system’s general health. The System Performance Summary consists of the following
four subsections:
•
Node Characteristics
•
Disk Volume Performance
•
Global Performance Indicators
•
System Performance Score
The purpose and contents of each of these subsections follow.
Node Characteristics
This subsection of the report (Example 3-1) gives general performance figures for the
node GPA has analyzed. For each line item in this subsection, the report shows a
measured value and, where it applies, the maximum value the GPA model expects.
