We are currently trialling Netflow Tracker and allowing our clients to view this information via a web-based portal.

Netflow Tracker takes information (Netflow Version 9) from our clients connections and stores them in a database for 7 days.

A graphical user interface then displays this information to our clients. Each client can only access their own connections. This real time monitoring of NetFlow allows clients to have the detailed information necessary to identify, isolate and troubleshoot network performance issues. It takes the raw numbers that make up the Netflow data generated from a routers interface and converts them to easy to read/interpret charts for analysis.

It answers such questions as

• Exactly what makes up my network traffic?

• Who are the users?

• What applications are they using?

• Who and what are consuming the bandwidth?

• Are there worms and viruses in my network, where are they, where did they come from, and where are they going?
