Hello,
does anybody on this list know of a free/open source tool that collects NetFlow AS aggregation records from a number of routers and produces traffic graphs per AS that show how much traffic came in from or went out to a given AS, and over which link (-> multiple upstreams/peering links)?
I'm asking because I've made something like that on a whim for Monzoon Networks to help with BGP traffic engineering, and would be happy to polish it up a bit and then release it, but if the solution is already out there (and better than what I've come up with ;), I wouldn't bother.
Cheers,
Manuel

In my old ISP days, I used JFFNMS for this (http://www.jffnms.org/)
It was very easy to configure and besides its stupid name, that thingy was quite useful. Time has gone by (4 years or so) and it might have become more useful since then.
As usual, YMMV
Cheers, Viktor

Hello! I am using nfsen from sourceforge.

Hello again,
thanks all for your feedback - I've had a look at NfSen and JFFNMS, but couldn't figure out whether they'd do what I wanted without actually installing/configuring them.
Anyway - here are some screenshots; if there's any interest, let me know. What Stan said is probably true - most of those NetFlow tools are quite focused on the respective author's specific task, and this is no exception. ;)

Have a nice evening!

Hey Manuel,
that's a nice statistic there. Which tool did you use to generate the output?

Hello Gunther (and everyone else who asked),
that's a nice statistic there. Which tool did you use to generate the output?
As I indicated in my first message in this thread, it's something that I wrote for Monzoon. It works with two small Perl scripts, RRDtool (what else ;) and some PHP for the web interface. Since there does seem to be some interest in this after all, I'll clean it up a bit and make it available for downloading. I'll let you know on this list when it's ready.
Cheers,
Manuel

Time to make good on my promise - here it is:
https://neon1.net/as-stats/as-stats-v1.tar.gz
Instructions on installing/using it can be found in the README file inside the archive. If anyone's using it (or at least attempting to ;), please let me know.
And for those who don't know what I'm talking about: the screenshots I posted on this list a few weeks ago can be found here:

Hi Manuel
With which tool did you made these graphs ? They look interesting to me.
Best regards
Matthias

last time I checked it a couple of years ago, there were no good open-source tools for Netflow analysis. Every available tool was too much oriented on the author's specific task, and they were not flexible or scalable enough.
There are few commercial and not-too-much-expensive tools of decent quality though.
Please say hi to Monzoon guys if anyone remembers me there :)
cheers, stan
