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.
