Accessing Realtime Performance Statistics 453
To reset counters in the current view For absolute values, you can
reset the counters in the current view by clicking Reset Counters In
View. Resetting counters applies to the current view only. The
performance data continues to be collected. The view shows when you
reset the counters.
To show the original counter values For absolute values, you can
see the original counter values by clicking Show Original Counters. If
you click Show Original Counters, the performance data values that
were displayed since view reset are replaced with the current original
counters.
Viewing Historical Data
To see historical performance data in a graph, click the History tab.
Graphing starts when you click the tab and is based on the polling
interval you selected.
To see details for historical data You can see historical data for the
objects in the scope you selected. For example, if you selected a Mobility
Domain as the scope, you can see historical data for the Mobility Domain,
WX switches in the Mobility Domain, or WX ports.
To see the objects available in the scope, click the button next to Select
Detail (the button text depends on what scope you selected), and select
the object whose historical data you want to see.
To hide the list of objects that you can graph, click Hide Object
Selector. This allows you to see the graph in the full width of the
Statistics tab in the View panel.
The following figure shows the historical data in delta values for the 10
minutes between 19:10:06 and 19:20:06. If the polling interval is 60
seconds, the graph is refreshed every 60 seconds, but the Time axis
always spans 30 minutes.
