Netflow has always been a topic of interest to me. It allows Cisco devices to track exactly how your network bandwidth is used. For example, using NetFlow allows me to see the applications (ports) using my Internet connection, how much bandwidth they are consuming, the source and destination IP addresses that are consuming the most traffic, and so on. Handy information!

Anyhow, Solarwinds has just released a new (free) tool that allows you to chart and graph all this information. This is definitely a plug for their enterprise Orion software which lets you manage bunches of devices...but hey, a free tool is still a free tool :).
