NetFlow Viewer

[jkaftan]

I am looking for a free NetFlow viewer to track the traffic on two edge routers. Does anybody have a good freeby?

ManageEngine has a nice tool for this. The free version allows you to monitor two interfaces. However, since you have to monitor both ingress and egress interfaces to get good stats, that probably only takes care of one router.

I have installed that one and I am playing with it. I just want to view the ingress and egress of my serial port on two seperate routers. Is there a way to make that work?

It seems to want to show me stats for two ports.

Netflow only monitors in one direction per interface. So, in order to get both ingress and egress on an interface, you need to monitor all the interfaces that contribute to, or accept traffic from, that interface. If you only have two relevant interfaces on a particular router then you can monitor them using the free version of that tool. You won't be able to monitor ingress and egress stats for two different routers unless they've changed the number of monitorable interfaces in the free tool.

I was able to get my desired affect by doing an "ip route-cache flow" on both of my interfaces. Then I went into License Management and selected "unmanage" for my inside interfaces. The result is that I see just the in and out of my WAN interfaces on both routers. Hopefully I will be able to get by with the free version with this setup.
