Statistics
3-6 RMON Statistics
To choose Total , Delta , or Accum :
1. Click on the Total radio button; after the completion of the current polling cycle
plus one complete polling cycle, the screen will display the total count of
statistics processed since the entry was created or since the device was last
initialized, whichever is most recent. These totals are updated after each
polling cycle.
2. Click on the Delta radio button; after the completion of the current polling
cycle plus two more polling cycles, the screen will display the count of
statistics processed during the last polling interval. These counts will be
refreshed after each polling cycle.
3. Click on the Accum radio button; after the completion of the current polling
cycle plus two more polling cycles, the screen will display a fresh cumulative
count of statistics. Note that making this selection does
not clear device
counters; you can still re-select Total for the total count since the device was
last initialized.
Note that switching the statistics displays among Total , Delta , and Accum does
not effect the displayed peak values, as peak values are always Delta values.
To temporarily freeze the statistics display, select the Freeze Stats option; in this
mode, statistics will continue to be collected, but the display will not update. To
resume normal updates, click again to de-select the freeze option.
Printing Statistics
The Print button located at the bottom of the Statistics window allows you to
print the current snapshot of statistical data. When you select Print , a standard
Windows print window like the sample shown in Figure 3-2 will appear.
