HP StorageWorks XP Performance Advisor Software v4.6 User and Troubleshooting Guide (T1789-96094, June 2010)

The performance graph also displays the Dispatch Threshold value that is the threshold value for which
an alarm was configured to be dispatched. The Dispatch Threshold value is displayed for only one
resource and metric combination. It is disabled if you choose multiple resources and metrics. The
Dispatch Threshold value acts like a watermark and helps you know the maximum threshold limit that
was set and the current performance value of the resource. Appropriate legends are displayed to
differentiate the resource current value from the Dispatch Threshold value. In the above figure, the
green line signifies the Dispatch Threshold value. After the performance graphs are plotted, you can
use the following chart options in the Chart Work Area. In addition, you can also resize and rearrange
the chart windows in the Chart Work Area. For more information on using the chart options, see
“Plotting charts” on page 213.
