argus and Netflow

[Riccardo Veraldi]

dear Carter,
thanks for your reply.

The problem is that we have 3x 10Gbps links and it's kind of impossible 
to monitor that huge amount of traffic
with argus directly.
So we are doing it with netflow and netflow analyzer.
But in this way I am unable to run my custom perl scripts which analyze 
argus data, and tell me if someone is probably
doing peer to peer or other nasty things.
can I collect netflow data, save it in argus format and analyze it with 
my scripts ?

thank you

Riccardo
