Accessing Realtime Performance Statistics 451

Generally, the scope is an aggregate object, which means that it is made up of sub-objects. (The exception is when a scope is a set of ports.) When you see performance data for the aggregate object, you are seeing the sum of the data of the sub-objects. For example, a WX consists of ports. Performance data for a WX is the sum of per-port performance data values.

7To change the level of detail, click the button next to Select Detail (the button text depends on what scope you selected), and select a level of detail from the list. (For more information, see “To see details for performance data” on page 452.)

If you make changes in the network plan that affect the object membership list (for example, you add a WX to a Mobility Domain and deploy it), the current monitoring session does not update this change. Stop the session, and restart performance monitoring for the scope.

For more information about viewing performance data, see “Viewing Performance Data” on page 451. For more information about exporting data, see “Exporting Performance Data” on page 455.

Viewing Performance When looking at performance data in the Statistics tab, you can see the Data data in absolute or delta values.

Delta (rate of change) values are calculated with the following equation:

value at end of polling interval - value at beginning of polling interval time difference (in seconds)
