How To Use the Statistics Screens To Analyze Router Operation

How To Manage the Statistics ScreensHow To Manage the StatisticsScreens

The statistics displayed on any of the statistics screens are cumulative values gathered since the router last booted. You can reset the values to zero at any time, by using a command on the individual statistics screen (see below) or by using the Network Control Language (NCL) Interpreter’s Reset command. (Refer to page 7-21.)

All statistics are dynamic and are updated periodically. The update period is configurable using the Screen Refresh Rate parameter in the Configuration Editor. The default rate is three seconds.

At the bottom of a statistics screen is the prompt:

PRESS: ’r’ for reset, Down, Up, <- to exit

You have the following choices:

To reset a displayed value to zero, use the [v] or [^] key to position the pointer on the line containing the value to be reset, then press [R]. Resetting a value also resets all other values displayed on the same horizontal line. (Values displayed on the same horizontal line refer to the same circuit, circuit group, or network interface.)

Occasionally a screen may display a number prefixed with an asterisk (for example, *234345677). The asterisk indicates that the number is too large to display, and that the number’s most significant digits are truncated. This is when you may wish to reset the value.

To exit a statistics screen at any time, press the [<] key. The console then returns to the Statistics Screen menu. (Refer to figure 6-2.)

For an example of each statistics screen type, along with a description of each statistics data category, refer to the Operator’s Reference.
