Monitoring Cisco Netflow Data

Netflow is a great feature of Cisco IOS that allows you a view into the traffic that flows over your Cisco network devices, what that traffic is, where it came from and where it is going.

We wanted to make good use of this information and so we started looking for a way for Opsview to monitor it.

With a little configuration of IOS and some open source magic we achieved just that. Now our Opsview servers are keeping tabs on the data moving across our Cisco devices.

So true to our open source way of life we published our setup as part of the Opsview documentation.
