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

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 of the data points from the current background performance

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 will show that it is initializing.

Time, End Date, and End Time fields.

free space, otherwise the file will not load. 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. When the metric value exceeds 99,999, it appears in thousands
