Managing Ethernet MicroLAN Switches

Timer Statistics

You can use the Timer Statistics windows to gather statistical information concerning the repeater channels on your Ethernet MicroLAN Module and its boards and/or ports over a user-set time period. Statistics are displayed both numerically and graphically, using color-coded, dynamic bar charts. These bar charts display the elapsed, average, and peak values for percent load, percent collisions, and percent errors at the repeater, board, or port level. The values are color-coded as follows:

¥Green (Elapsed) Ð Indicates the level of activity during the last time interval.

¥Blue (Average) Ð Indicates the average levels of activity over all timer intervals since the window was invoked.

¥Magenta (Peak) Ð Indicates the peak level of activity over all time intervals since the window was invoked.

The displayed statistics will automatically update using the time interval you have set; allowable time intervals range from one second to 23 hours/59 minutes/59 seconds. You can also refresh the statistics accumulated in the Timer Statistics window at any time by clicking the Clear button. This will only reset the counters at the Timer Statistics window; the statistical counts maintained by the device are not affected. The time under the Clear button will also update, indicating the last time that the Timer Statistics window was cleared.

NOTE

The time interval set in the Timer Statistics window functions independently from the polling interval you have set for the monitored device via the Device Management page of the Options window.
