Viewing current background performance monitor data

1. In the Array Management Window (AMW), click the Performance tab.
2. Click the Launch background performance monitor link.
   The View Current option is available only when performance monitoring is in progress. You can tell that background performance monitoring is in progress by the presence of the In Progress icon next to the Stop link. The View Current Background Performance Monitor dialog is displayed.
3. In the Select metric drop-down list, select the performance data that you want to view.
   You can select only one metric at a time.
4. In the Select an object(s) list, select the objects for which you want to view performance data.
   You can select up to five objects to monitor on one graph. Use Ctrl-Click and Shift-Click to select multiple objects. Each object is plotted on a separate line on the graph.

   The resulting graph shows all the data points from the current background performance monitoring session.

   NOTE: If you do not see a line that you defined on the graph, it might be overlapping another line. If you perform the View Current option before the first sampling interval elapses (10 minutes), the graph shows that it is initializing.

    
5. (Optional) To change the time period plotted on the graph, make selections in the Start Date, Start Time, End Date, and End Time fields.
6. To close the dialog, click Close.
