Traffic monitor

[balanga]

Any suggestions for a traffic monitoring program? (Ideally for WWAN)

It depends on what traffic you want to monitor.
For a bespoke and non-realtime solution, an IPS/IDS may be the way to go. Try hunter-nsm, which uses BRO/SNORT, with ELK.

There are many other competing platforms - suricata or so,

And for a real-time monitoring, you may want to rely on packaes like pftop,dnstop, etc.

I basically wanted something which would report usage between two dates... not really bothered about realtime usage.

This means you need to have something running that stores this information. That's something different from real-time information.

Any one of these will require setting up a central server and maintaining it.
