Query real time network throughput

[ps.swt]

I'm looking for a possibility to monitor at least the real time network-throughput (up/down) to a backend-database or to query it somehow. Is it possible to query the Traffic Graph, to log its data to a backend database or to use a package-addon for this task?

With BandwidthD i already log all details to a PostgreSQL database, how this can be accomplished for the real time network throughput?

Best regards

will probably needs some tweaking to get it to work
