Displaying performance information on links

You can configure links between devices to display bandwidth or other performance information from poll policies.

1. Back up and edit the following file: $NMGUI_HOME/profile/etc/tnm/topoviz.properties.
2. Update the following properties:

   topoviz.link.labels.perfs.enabled

   Set this property to true to display performance information on the link labels. The default is false.

   topoviz.link.labels.policy

   Set this property to the name of an appropriate poll policy for which to display metrics. For example, snmpInBandwidth, snmpOutBandwidth, or sysUpTime. The default is an empty string, which means no poll policy is selected. If no poll policy is selected and performance information is enabled, then the bandwidth from the most recent discovery is displayed.

   topoviz.link.labels.policy.aggregator

   Set this property to the desired aggregator. Allowed values are: MAX, SUM, MIN, AVERAGE. The default is MAX.

   topoviz.link.labels.decimal.scale

   Set this property to the required number of digits after the decimal point. This value must be a positive integer. The default is 3.

   topoviz.link.labels.speed.unit

   Set this property to bits to display the speed in bits per second, or bytes to display the speed in bytes per second.

3. Save and close the file.
