<div><p>To effectively monitor system performance, you must decide which
|
||
|
|
aspects of system performance you want to monitor. Management Central offers
|
||
|
|
a variety of performance measurements, known as <span class="uicontrol">metrics</span>,
|
||
|
|
to help you pinpoint different aspects of system performance.</p>
|
||
|
|
<div class="section"><p>The <span class="uicontrol">Metrics</span> page in the <span class="uicontrol">New
|
||
|
|
Monitor</span> window allows you to view and change the metrics that
|
||
|
|
you want to monitor. To access this page, select <span class="uicontrol">Monitors</span>,
|
||
|
|
right-click <span class="uicontrol">System</span>, and then select <span class="uicontrol">New
|
||
|
|
Monitor</span>. Fill in the required fields, and then click the <span class="uicontrol">Metrics</span> tab.</p>
|
||
|
|
<p>When
|
||
|
|
you configure a monitor, you can use any metric, a group of metrics, or all
|
||
|
|
the metrics from the list to be included in your monitor. Metric types you
|
||
|
|
can use in your monitor include the following:</p>
