Viewing Trending Information for Performance
The management server can display trending information in its charts. For example, you can
configure Performance Manager to display trending information for the next week. This information
can give you an indication of an element's future performance based on past performance.
Keep in mind the following:
• An element's performance can drastically change in the future. Keep in mind that the data trends
are just assumptions and should not be treated as fact.
• Trending requires at least two sets of data gathered within the frequency specified.
To view trending information:
1. Access Performance Manager as described in ”Accessing Performance Manager” on
page 394.
2. Click the element whose performance you want to see.
3. Under the Monitoring tab in the lower-left pane, select the element again. In some instances, you
may need to select an element's port, such as a switch.
4. In the lower-left pane on the Monitoring tab, click a performance-monitoring option.
The performance monitoring options listed in this figure vary according to the type of element.
The monitoring buttons in the figure are for a switch.
5. Click the Edit Chart Property ( ) button in the lower pane.
6. In the Performance Graph Editing Dialog window, enter a number in the Trend box.
The number corresponds to the number of frequency intervals for which the trending information
will be provided. For example, if you enter 5 in the Trend box, the chart provides trending
information for five frequency intervals, such as five weeks if weeks was selected from the
Frequency menu. If the frequency is set to All, the trend interval is an hour.
7. Click OK.
The trending information is displayed in the chart.
