Monitoring virtual circuits

The Virtual Circuits report shows the top virtual circuits by volume and their average throughput. Virtual circuit traffic inbound into your LANLocal area network is reported separately from outbound traffic.

You can choose show the entire circuit traffic by adding in a category to represent the remaining virtual circuitlogical definitions that partition a a physical network circuit and used to determine what traffic passes through it and how much traffic on your network; the cumulative stack on the throughput chart represents all the virtual circuit traffic through the appliance. This will help you understand the significance of the top virtual circuits relative to the whole.

In addition to showing the data as a stacked cumulative display, you can choose to display the data as a line chart with a common zero baselineused by monitors and performance reports to establish a standard by which sunsequent performance can be measured. You can optionally show the top three applications for each of the top virtual circuits.

This report answers questions such as:

  • What are the top virtual circuits in my network?
  • How much bandwidth does my virtual circuit for the New York branch typically consume?
  • I reserved 200 Kbps for this virtual circuit; is that amount of bandwidth really needed or is it to little?
  • Do each of my branches (partitioned by virtual circuit) have the same top applications?
  • What are the top apps per virtual circuit?
  • What are the top internal and external hosts per virtual client?

Drill into the applications for a specific virtual circuit by clicking on the virtual circuit name in the charts or the tables below the charts. The applications graph will be shown filtered for the specified virtual circuit.

Average bandwidth is calculated as the total bits observed in the charting interval divided by the number of seconds in that interval. E.g. For a chart with an hour of data, the intervals are five minutes.
