Viewing performance graphs for resources
XP Performance Advisor logs a new record in the Alarms History table when either of the following
conditions are met:
• The performance of a resource rises beyond the set threshold limit.
• The performance of a resource drops below the set threshold limit.
The current value of the resource is displayed under Value in the Alarms History table. Click the
corresponding link to view the performance value when the resource crossed the threshold level or
dropped below the threshold level. For a resource that has crossed the threshold limit, the performance
graph includes the following:
• Performance value when the resource crossed or dropped below the threshold level.
• Includes data collected 1 hour prior to the resource crossing or dropping below the threshold level.
• Continues to show data collected upto 1 hour after the resource crossed or dropped below the
threshold level (if performance data is available).
For a resource that has dropped below the threshold limit, the performance graph includes the
following:
• Performance value when the resource dropped below the threshold level.
• Includes data collected 1 hour prior to the resource dropping below the threshold level.
• Continues to show data collected upto 1 hour after the resource dropped below the threshold level
(if performance data is available).
The data available shows the progress trend of the resource. The performance value displayed under
Value is in sync with the time displayed under Time Updated. It implies that XP Performance Advisor
retrieves the performance value for the time displayed under Time Updated. The performance value
is updated till the time the resource'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 XP Performance Advisor retrieves the latest
performance value.
