Enterasys Networks 6000, Matrix E7 manual Viewing Total, Delta, and Accumulated Statistics

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 option buttons located at the bottom of each 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.

The statistics windows use the polling interval you have set for the monitored device via

TIP the Device Management page of the Options window. See your Element Manager User’s Guide for more information on setting the Chassis Manager polling interval.

To choose Total, Delta, or Accum:

1.Click on the Total option 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 option 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 option 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.

NOTE

If you reset your device, you must first close, then re-open the Statistics window to refresh peak values.
