Viewing Trunk Utilization

You can view the number of active channels per trunk over time in the Web interface's Trunk Utilization page. The page displays a graph, where the x-axis indicates the time (hh:mm:ss) and the y-axis the number of active trunk channels.

The Trunk Utilization page is applicable only to the Gateway application.
To view the graph, your device must be connected to and configured with trunks.
To view the graph, you must first disable the SBC application.
If you navigate to a different page, the data displayed on the graph and all its settings are cleared.
To view the number of active trunk channels:
1. Open the Trunk Utilization page (Monitor menu > Monitor tab > Performance Monitoring folder > Trunk Utilization).

2. From the 'Trunk' drop-down list, select the trunk for which you want to view active channels.
3. For more graph functionality, see the following table:

Zoom slide ruler and buttons

Increases or reduces the trunk utilization display resolution concerning time. The Zoom In button increases the time resolution; the Zoom Out button decreases it.

The minimum resolution is about 30 seconds; the maximum resolution is about an hour.
