<div><p>After you have collected performance data, learn how to display
|

the data using the most appropriate tool for your purposes.</p>
|
|
<div class="section"><p>Displaying performance data helps you analyze your system's performance
|
|
more accurately. Performance data can be displayed in many different ways;
|
|
however, you may find a certain performance application more appropriate in
|
|
some situations. Most applications display data collected with either Collection
|
|
Services or from a performance trace. The best way to access that data depends
|
|
on whether you are attempting to resolve a performance problem, are monitoring
|
|
your system performance to plan for future growth, or are identifying trends.</p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Display near real-time performance data</h4><p>Use the
|
|
following tools to display current or very recent performance information:</p>
|
|
<dl><dt class="dlterm"><span class="keyword">i5/OS™</span> commands</dt>
|
|
<dd>There are many commands in the base operating system that will let you
|
|
view current information about specific areas of system performance.</dd>
|
|
<dt class="dlterm">Performance Tools plug-in</dt>
|
|
<dd>The Performance Tools licensed program includes a plug-in for <span class="keyword">iSeries™ Navigator</span> that displays
|
|
performance data from Collection Services collection objects. You can also
|
|
view detailed information about the jobs on the system and print Performance
|
|
Tools reports.</dd>
|
|
<dt class="dlterm">System and Job monitor</dt>
|
|
<dd>These monitors display performance data for many system elements. Monitor
|
|
data is based on the collection objects, and will display data as it is collected,
|
|
according to the collection interval in Collection Services.</dd>

<div class="section"><h4 class="sectiontitle">Display historical performance data</h4><p>Use the following

<dd>PM <span class="keyword">iSeries</span> automates

clear reports to help you manage system resources and capacity.</dd>
|

<dt class="dlterm">Graph history</dt>
|
|
<dd>Graph history provides a graphical display of up to a week's worth of
|
|
performance data depending on the retention period in Collection Services.
|
|
With PM <span class="keyword">iSeries</span>,
|

Graph History can display much longer periods of data collection.</dd>
