Enterasys Networks MicroMMAC-T manual Viewing Elapsed, Average, and Peak Activity Levels

Token Ring Statistics

Using these radio buttons, you can choose whether to view the statistics gathered since the MicroMMAC-T was last restarted or (if you are monitoring port-level statistics) since the station was first inserted (Total), during the last polling interval (Delta), or accumulated from zero at a user-defined point (Cumulative). You set the interval to update information (from 1 second to 23 hours, 59 minutes, 59 seconds) by using the clock symbol at the bottom of the window (See Setting the Statistics Poll Interval, below, for details on using the clock symbol).

To choose Total, Delta, or Cumulative:

•Click on the Total radio button. After the completion of the current polling cycle plus one complete polling cycle, the screen will display the sum of statistics processed since the MicroMMAC-T was last restarted or (if you are monitoring port-level statistics) since the station was first inserted. These totals are read from the device and updated at each subsequent polling interval.

•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 are refreshed after each polling cycle.

•Click on the Cumulative radio button. After the completion of the current polling cycle, the screen will display the count of statistics processed during the last polling interval, and then will accumulate statistics with each polling cycle thereafter until another display option is chosen.

Viewing Elapsed, Average, and Peak Activity Levels

Timer Statistics windows measure activity levels for different network events on a color-coded strip chart. An example of this chart is shown in Figure 3-2.

The activity states and their colors are:

•Elapsed (Green) — Indicates the level of activity during the last time interval.

•Average (Blue) — Indicates the average level of activity over all time intervals since the window was invoked.
