<div><p>Contains a description of the available options for managing

and displaying records of performance data.</p>
|
||
|
|
<p>Graph history displays data contained in the collection objects created
|
||
|
|
by Collection Services. Therefore, the type and amount of data available is
|
||
|
|
dependent on your Collection Services configuration.</p>
|
||
|
|
<p>The amount of data that is available to be graphed is determined by the
|
||
|
|
settings that you selected from the Collection Services properties, specifically
|
||
|
|
the collection retention period. Use <span class="keyword">iSeries™ Navigator</span> to
|
||
|
|
activate PM <span class="keyword">iSeries</span> over multiple
|
||
|
|
systems. When you activate PM <span class="keyword">iSeries</span>,
|
||
|
|
you can use the graph history function to see data that was collected days
|
||
|
|
ago, weeks ago, or months ago. You go beyond the realtime monitor capabilities,
|
||
|
|
and have access to summary or detailed data. Without PM <span class="keyword">iSeries</span> enabled,
|
||
|
|
the graph data field supports 1 to 7 days. With PM <span class="keyword">iSeries</span> enabled,
|
||
|
|
you define how long your management collection objects remain on the system:</p>
|
||
|
|
<ul><li><span><img src="./delta.gif" alt="Start of change" /><span class="uicontrol">Detailed data</span> (attribute type *PFR
|
||
|
|
in QMPGDATA.LIB or QPFRDATA.LIB)<img src="./deltaend.gif" alt="End of change" /></span><p>The length of time that management
|
||
|
|
collection objects remain in the file system before they are deleted. You
|
||
|
|
can select a specific time period in hours or days, or you can select <span class="uicontrol">Permanent</span>.
|
||
|
|
If you select <span class="uicontrol">Permanent</span>, the management collection
|
||
|
|
objects will not be automatically deleted.</p>
|
||
|
|
</li>
|
||
|

<li><span><img src="./delta.gif" alt="Start of change" /><span class="uicontrol">Graph data</span> (attribute type *PFRDTL
|
||
|
|
in QMGTC2.LIB)<img src="./deltaend.gif" alt="End of change" /></span> <p>The length of time that the details and properties
|
||
|
|
data that is shown in the Graph History window remains in the system before
|
||
|
|
it is deleted. If you do not start PM <span class="keyword">iSeries</span>,
|
||
|
|
you can specify one to seven days. If you do start PM <span class="keyword">iSeries</span>,
|
||
|
|
you can specify 1 to 30 days. The default is one hour.</p>
|
||
|

|
||
|
|
in QMGTC2.LIB)<img src="./deltaend.gif" alt="End of change" /></span> <p>The length of time that the data collection points
|
||
|
|
of a graph can be displayed in the Graph History window or remain in the system
|
||
|
|
before they are deleted. No details or properties data is available. You must
|
||
|
|
start PM <span class="keyword">iSeries</span> to enable
|
||
|
|
the summary data fields. The default is one month. <span><img src="./delta.gif" alt="Start of change" />The summary
|
||
|
|
data is summarized in one-hour intervals and does not support second- and
|
||
|
|
third-level details.<img src="./deltaend.gif" alt="End of change" /></span></p>

<li><img src="./delta.gif" alt="Start of change" /><span class="uicontrol">Graph history status</span><p>The Graph History
