value is updated till the time the component's performance rises or drops below the set threshold level.
Once the performance value rises or drops below the threshold, a new record is posted in the Alarms
History table and a new graph is generated as, and when P9000 Performance Advisor retrieves the
latest performance value.
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
component and metric combination. It is disabled if you choose multiple components and metrics.
The Dispatch Threshold value acts like a watermark and helps you to identify the maximum threshold
limit that was set and the current performance value of the component. Appropriate legends are
displayed to differentiate the component current value from the Dispatch Threshold value. In the above
image, the green line signifies the Dispatch Threshold value. After the performance graphs are plotted,
use the following chart options in the Chart Work Area. In addition, resize and rearrange the chart
windows in the Chart Work Area. For more information on using the chart options, see “Plotting
charts” on page 264.
