<h1 class="topictitle1">Performance Tools reports</h1>
|
||
|
|
<div><p>Performance Tools reports provide information on data that has
|
||
|
|
been collected over time. Use these reports to get additional information
|
||
|
|
about the performance and use of system resources.</p>
|
||
|
|
<p>The Performance Tools reports provide an easy way for you to look at your
|
||
|
|
collected data and isolate performance problems. After you have collected
|
||
|
|
performance data over time, you can print the reports to see how and where
|
||
|
|
system resources are being used. The reports can direct you to specific application
|
||
|
|
programs, users, or inefficient workloads that are causing slower overall
|
||
|
|
response times.</p>
|
||
|
|
<p>Collection Services provides data for most of the Performance Tools reports
|
||
|
|
with the exception of the Transaction, Lock, and Trace reports. You must use
|
||
|
|
the <span class="cmdname">Start Performance Trace (STRPFRTRC)</span> and <span class="cmdname">End
|
||
|
|
Performance Trace (ENDPFRTRC)</span> commands to collect the trace information
|
||
|
|
for those three reports.</p>
|
||
|
|
<p>The following list describes each report, gives a brief overview as to
|
||
|
|
why you would use a particular report, and links to samples of each report.
|
||
|
|
In addition, each report is discussed in detail in the Performance Tools book.</p>
