Accessing Realtime Performance Statistics 455
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.

Viewing Performance
Data
When looking at performance data in the Statistics tab, you can see the
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)
For example, if the number of octets in is 11,101,288 at the beginning of
the polling period, the number of octets in is 11,146,904 at the end of
the polling period, and the time difference is 60 seconds, the delta value
is 760.267.
To change how you view data values, select Absolute to see absolute
values or Deltas to see rate-of-change values.
Using the Statistics tab, you can see performance data in different
formats:
■
Current data — When the Statistics tab appears in the main 3WXM
window, you see the current data in the Current tab. For more
information, see “Viewing Current Data” on page 456.

more information, see “Viewing Historical Data” on page 457.
