|
|
<div><p>This topic contains step-by-step instructions to view graph history
|
|
through <span class="keyword">iSeries™ Navigator</span>.</p>
|
|
<div class="section">Graph history is included in <span class="keyword">iSeries Navigator</span>.
|
|
To view the graph history of the data that you are monitoring with Collection
|
|
Services, do these steps:</div>
|
|
<ol><li><span>Follow the <span class="keyword">iSeries Navigator</span> online
|
|
help for starting Collection Services on either a single system or on a system
|
|
group.</span></li>
|
|
<li><span>From the <span class="uicontrol">Start Collection Services - General</span> page,
|
|
select <span class="uicontrol">Start IBM Performance Management for eServer <span class="keyword">iSeries</span></span> if
|
|
needed.</span></li>
|
|
<li><span>Make changes to the other values for the collection retention period.</span></li>
|
|
<li><span>Click <span class="uicontrol">OK</span>.</span></li>
|
|
<li><span>You can view the graph history by right-clicking either a system
|
|
monitor or a Collection Services object and selecting <span class="uicontrol">Graph History</span>.</span></li>
|
|
<li><span>Click <span class="uicontrol">Refresh</span> to see the graphical view.</span></li>
|
|
</ol>
|
|
<div class="section"><div class="tip"><span class="tiptitle">Tip:</span> <img src="./delta.gif" alt="Start of change" />If the graph history data is missing,
|
|
you can re-create it. To re-create the graph history data, right-click on
|
|
the object in <span class="keyword">iSeries Navigator</span> and
|
|
choose <span class="uicontrol">Create Graph History Data</span>.<img src="./deltaend.gif" alt="End of change" /></div>
|
|
<p>Once you
|
|
have launched a graph history, a window displays a series of graphed collection
|
|
points. These collection points on the graph line are identified by three
|
|
different graphics that correspond to the three levels of data that are available:</p>
|
|
<ul><li>A square collection point represents data that includes both the detailed
|
|
information and properties information.</li>
|
|
<li>A triangular collection point represents summarized data that contains
|
|
detailed information.</li>
|
|
<li>A circular collection point represents data that contains no detailed
|
|
information or properties information.</li>
|
|
</ul>
|
|
</div>
|
|
<div class="section"><img src="./delta.gif" alt="Start of change" />The system adds data from the active collection object
|
|
(*PFR attribute) to the *PFRDTL and *PFRHST collection objects when the following
|
|
occurs:<ul><li>If the collection object properties is set to add graph data and summary
|
|
data when cycled, the collection is cycled.</li>
|
|
<li>If the already cycled object is selected and the menu option to summarize
|
|
the data is selected.</li>
|
|
<li>If a system monitor is running, then data is added to the *PFRDTL object
|
|
only, as the system monitor is running.</li>
|
|
</ul>
