<h1 class="topictitle1">Collect system performance data</h1>
|
||
|
|
<div><p>Collection Services regularly collects information about system
|
||
|
|
performance. Often, analyzing performance data begins with this information.</p>
|
||
|
|
<div class="section"><p>Collecting data is an important step toward improving performance.
|
||
|
|
When you collect performance data, you gather information about your server
|
||
|
|
that can be used to understand response times and throughput. It is a way
|
||
|
|
to capture the performance status of the server, or set of servers, involved
|
||
|
|
in getting your work done. The collection of data provides a context, or a
|
||
|
|
starting point, for any comparisons and analysis that can be done later. When
|
||
|
|
you use your first data collections, you have a benchmark for future improvements
|
||
|
|
and a start on improving your performance today. You can use the performance
|
||
|
|
data you collect to make adjustments, improve response times, and help your
|
||
|
|
systems achieve peak performance. Performance problem analysis often begins
|
||
|
|
with the simple question: "What changed?" Performance data helps you answer
|
||
|
|
that question.</p>
|
||
|
|
<p>You can use Collection Services to collect performance
|
||
|
|
data, create performance files with the <span class="cmdname">Create Performance Data (CRTPFRDTA)</span> command,
|
||
|
|
convert them to current release with <span class="cmdname">Convert Performance Data (CVTPFRDTA)</span> command
|
||
|
|
or through the Performance Tools plugin in <span class="keyword">iSeries™ Navigator</span>,
|
||
|
|
and then create reports or create your own queries by using the information
|
||
|
|
in the performance database files.</p>
|
||
|
|
<p>For more information about performance
|
||
|
|
data, see the following:</p>
|
||
|
|
<dl><dt class="dlterm">Collection Services</dt>
|
||
|
|
<dd>See how to collect performance data for analysis and how to customize
|
||
|
|
your collections.</dd>

||
|
|
<dt class="dlterm">Performance database files</dt>
|
||
|
|
<dd>Find an overview of the performance database files that are available
|
||
|
|
to you and see detailed field data for each performance database file.</dd>
|
||
|
|
</dl>
|
||
|
|
<p>In addition, you can use either the Performance Management
|
||
|
|
APIs or the performance collection CL commands to start, end, and cycle collections,
|
||
|
|
as well as to change and retrieve system parameters for the data collected.</p>
