Re: Netflow collector that can forward flows to another collector based on various metrics.

Speaking as the maintainer of samplicator, I'm not sure it's what Drew
is looking for.

Samplicator just sends copies of entire UDP packets.  It doesn't
understand NetFlow/IPFIX or whatever else those packets might contain.

If I understand correctly, drew wants to forward some of the
NetFlow/IPFIX flows, based on source/destination addresses *within those
flows*.  Samplicator cannot do that (by a long shot).

pmacct sounds like a good suggestion.

(I used to have a Lisp program that could also do this, and adding an
API would have been trivial... but the program has been decommissioned
recently after >20 years of service.  Also I never got around to
cleaning that up so that I could distribute the source. :-)
