Have you used flow-tools?
http://www.splintered.net/sw/

You can configure it to filter on pretty much any parameter that's
contained
in the flow-export packets.  Then you send it to the report tool that's
included
in the flow-tools suite, after which you can put it through a perl
script or 
a graphing tool or whatever in near real-time.

            I know there is a way to do this, but what is the absolute
Defacto best method of tracking flows from Cisco/Juniper routers? I know
there is some freeware available such as cflowd but we really need
something that will alert us to trouble before it becomes a problem. We
don't mind buying an appliance to do this, and it doesn't have to be
freeware software, we just want something that will work.

Thanks,
