I think I remember seeing your e-mail to the list. My own cflowd setup
is pretty simple. Had 2 routers feeding one data collector. At the
moment, I'm not even collecting cflowd data.
Not only that, but our routers were nearly all ethernet, except for one DS3
to Holmdel, so I've very little experience with serial lines and netflow.
Sometimes I'm able to help people on the list by making informed guesses,
but I try to stop myself from making uninformed guesses to the list.
(My Dad's advice was "Better to let people think you are dumb than to
open your mouth and prove it to them").
So, I hope someone else on the list has a bit more relevant experience and
a smidge of free time to try to help you out with your question. Sorry
I can't be of better service to you.
You want to run 2 instances of cflowd on the same server? Going to
need a ton of shared memory and disk space and bandwidth to make that
work, assuming traffic is going to be heavy. As long as you make the
config files such that the streams don't cross each other, seems like it
should work. But remember Egon Spengler's advice: Crossing the
streams would be bad.
Editorializing a bit --- It isn't obvious to me: Why do you want
separate collectors? You might get more attention from the list if
you can convince people its an interesting problem that they might want
to pursue for their own purposes.
