Free Program to take netflow

[Dennis Burgess via NANOG <nanog () nanog org>]

I am looking for a free program to take netflow and output what the top traffic ASes to and from my AS are.   Something 
that we can look at every once in a while, and/or spin up and get data then shutdown..  Just have two ports need 
netflow from currently.

Thanks in advance.
