Changing the counter values
The counter values displayed in the Performance page can be either raw counter values or Delta/Sec
values. A raw counter value is the total count for a counter since the MP Router was booted.
Delta/Sec values are calculated as follows:
(y2 - y1) / (t2 - t1)
where y1 and y2 are successive raw counter values, and t1 and t2 are the associated time stamps at
which the y1 and y2 values were obtained from the MP Router.
By default, Delta/Sec values are shown in the Counters tab opens.
Use the following procedure to change the counter values that are displayed:
1. From the Switch Explorer, click the Perf icon in the Switch View, or from the Switch Manager, click
Performance in the navigation bar.
2. Click the Counters tab.
3. Click Show Raw Counters or Show Delta/Sec Counters in the task bar to toggle between the two
displays.
The type of counter that is displayed is shown in the Counters tab.
