Chapter 20 Performance Management and Historical Data

Viewing the Performance Manager Window

Note

When you choose Raw, the bar chart view is sometimes not available, and the
Summary Rule option is grayed out.

Step 7

Click Refresh Screen. The Refresh Screen button is grayed out when not available. The Refresh Screen
button is available for selection when Now is selected, or when any criteria has changed and you have
moved the cursor away from the changed value by clicking the Tab key or by using the mouse.

The performance information appears as a line chart by default. You can view performance information
as a Line Chart or as a Table Display by selecting the corresponding tab.

The performance information corresponds to the attributes’ value returned during the raw sampling
period. When a summary period other than raw is selected, the information appears according to the
summary rule.

Note

In some circumstances (possibly due to Cisco 12000/10720 Router Manager being shut down or
a heavy network load), polls can be missed. Performance Manager deals with this problem by
displaying missed polls in red. The missed poll value is replaced by the last valid value collected.
Performance Manager graphs and charts also indicate when an attribute started and stopped
being polled due to history storage criteria being added, edited or removed. Start and stop polling
events are shown in charts and tables. The start polling events point is shown in green, and the
stop polling events point is shown in red.

A polling events key is displayed for selection.
