Viewing information about the current background
performance monitor session
Before performing this task make sure that the background 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 in the View Current Background
Performance Monitor dialog.
1. In the Array Management Window (AMW), click the Performance tab.
2. Click the Launch background performance monitor link.
The View Current Background Performance Monitor dialog is displayed.
3. Hold the pointer over the Stop link.
A tooltip displays the time background performance monitoring was started, the length of time background performance monitoring
has been in progress, and the sampling interval.
NOTE: For an accurate elapsed time, do not use the Synchronize RAID controller module Clocks option while using
Performance Monitor. If you do, it is possible for the elapsed time to be negative.
Viewing current background performance monitor data
A background performance monitor graph plots a single performance metric over time for up to five objects. The x-axis of the graph
represents time. The y-axis of the graph represents the metric value. The metric value is displayed in thousands (K), when the value
exceeds 99,999, starting with 100 K until the number reaches 9999 K, then the value is displayed in millions (M). For amounts greater than
9999 K but less than 100 M, the value is displayed in tenths—for example, 12.3 M.
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.
