The trending information is displayed in the chart.
NOTE: If there is not enough data to display, Performance Manager does not display the chart.
For example, if you selected the weekly option from Frequency drop-down combo box menu and
you only have two days of data, a chart is not displayed regardless of the value in the Trend field.
Performance Manager does not display a chart if there is not enough data and the trending
number is ignored.
Removing Performance Data from a Graph
To remove multiple data from a performance graph:
1. Access Performance Manager as described in ” Accessing Performance Manager ” on
page 538.
2. In Performance Manager, click the graph you want to modify in the bottom-right pane.
3. Click the Edit Chart Property ( ) button in the lower pane.
4. In the Performance Graphic Editing Dialog window, click the button corresponding with the
data you want to remove from the graph.
5. When you are asked if you want to remove the data, click Yes.
6. Click OK.
7. Click the button in the lower pane.
Setting a Custom Period
You can format the graph to provide data within a custom time period. This feature can be
extremely useful for pinpointing performance changes. For example, assumed you changed the
firmware of a switch two weeks ago and you want to compare the performance of that switch
before and after you changed its firmware. You could create a graph that provides performance
data two weeks before you changed the firmware. You could then create another graph that
provides performance data two weeks after you changed the firmware.
IMPORTANT: If you change the date in the field to a date that does not exist in a month, the
software automatically calculates the date to the next month. For example, if you enter
2003/11/31, the software assumes the date is 2003/12/01.
To set a custom period:
1. Access Performance Manager as described in ” Accessing Performance Manager ” on
page 538.
2. Click the element for which you want to see its performance.
