RMON Statistics 4-5
Statistics
The percentages displayed to the right of the numerical values for these fields
indicate what percentage of all packets transmitted on the network segment were
of the noted size. Unless the network segment has experienced a significant
number of runts and/or giants (which are not counted in this group), these
percentages will add up to 100. The pie chart in the center of the window provides
a graphical view of the percentage breakdown; colors in the pie chart correspond
to colors in the percentage display boxes. Values listed to the right of the pie chart
indicate peak delta values recorded since the statistics screen was launched, and
the date and time they occurred.
Viewing Total, Delta, and Accumulated Statistics
By using the Total, Delta, and Accum radio buttons located at the bottom of the
Statistics window, you can choose whether to view the total statistics count (since
the last time the device was initialized), the statistics count during the last polling
interval, or a fresh accumulation of statistics begun when the Accum button was
selected.
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.
TIP
The statistics windows use the polling interval you have set for the monitored device via
the Device Properties window. See your Installing and Using guide for more
information on setting the polling interval.
NOTE
If you reset your device, you must first close, then re-open the Statistics window to refresh
peak values.
