NetFlow Tracker

Per-AS data

If your router uses BGP to route traffic it will provide source and destination origin or peer AS numbers in its NetFlow data. NetFlow Tracker creates optimised bi-directional charts for each AS just as it does for each interface. An AS chart is only available for a single device as otherwise there is a high chance that some or all traffic will be accounted for multiple times by multiple routers. You can use the Filter Editor to create a report or chart based upon an AS and data from multiple routers.

To view the ASs routed by a given router, click the ASs link in the navigation menu at the top of the interface report:

The AS list is similar to the interfaces list, but does not show percentage utilization.

Working with Charts

Charts are one of the most useful ways of working with data in NetFlow Tracker. A chart lets you quickly pick out an area of interest to examine in further detail.

A chart displays the elements that contributed most to the overall total traffic or packet rate over the charted time range. By default, at most ten elements are charted but this can be configured in the Report Settings page.

Viewing earlier or later data

You can easily look at earlier or later data by using the forward and back buttons above the chart:

Note that when you open a device or interface chart from the device or interface lists it will automatically to keep up to date, but using the forward or back buttons will prevent this from happening.

Changing the displayed chart

All charts have several views, only one of which is displayed at a time. You can change which one is displayed using the tabs above the chart:

In this case, the utilization chart is displayed and the corresponding tab is raised.

The chart legend

Each charted element has a corresponding row in the legend below the chart. The legend may also have a row for other elements that were not big enough to be charted separately. Depending on the type of chart, some elements in the legend may be underlined; this indicates that more information is available by hovering the mouse over the text.
