The graphs are generated from nfsen and allow you to see (for instance) the
traffic for a specific network prefix for a interface on one netflow source.
It also allows you to see (as pie charts) the ratio between different
prefixes over a period of 5 minutes or a selectable period. Also, there are
graphs based on source and destination AS (per interface), with the
possibility of seeing the ratio between ASes (as a pie chart).
It's been under development and testing at the ISP I work for, for about 6
months, but I have to do some code cleanups before I can release it. Also,
the module doesn't support profiles with channels, or a non-standard plugin
topology. Another important issue is if my employers will allow me to
release this module as open source, because it was developed with the time
and resources of the company I work for... We'll wait and see. :)

Hi Adrian,
Is this plugin for nfsen and are the graphs for example pie-charts (in a
earlier thread you mention it) and other "nice to have" ways to
presentate the stats you can get when using nfsen's "Statistics
timeslot" output? Making reports for these stats in different graphs is
something i would love to have.
For a detailed analysis you need to zoomin from your netwerk, to 1
source and finally to a specific interface or even source/destination
IP. Combining these sources to create graphs would be awsome.
If you need someone to test, i would be glad to help.
Best regards,
Koen
