Viewing Performance Data400
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 menu and you only have two days of
data, a chart is not displayed, regardless of the value in the Trend box. 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 394.
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 Graph Editing Dialog window, click the Delete ( ) 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, assume 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.
To set a custom period:
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 component, such as a port on a switch.
4. In the lower-left pane on the Monitoring tab, click a performance monitoring option.
The performance monitoring options vary according to the type of element.
5. Select Custom from the Period combo box in the lower pane.
The Performance Graph Editing Dialog window appears when you select the Custom option and
there are no previous custom settings.
6. In the Performance Graphic Editing Dialog window, select the Custom option near the lower-left
corner.
