nfsen-ng looks great, thanks for pointing it out! I plan on releasing a backend (and home-made frontend) for nfsen that can be used to generate graphs for traffic engineering. For example, by having a list of "interesting" prefixes in your network you can see (as a rrd graph) how much traffic flows to that prefix on specific devices and interfaces. So you can have a better idea how to balance traffic when some links reach congestion. The same thing can be done with AS information, and you can get a "Top AS" per interface.
There is some cleanup and some documenting I need to do and I'll release it on github. It worked quite well for ~10 years in the company I work for, but now they're using paid tools from Arbor. I will let the mailing list know when it's released.
