Hello,
One question I'm often asked is if there is software that can monitor the activity of a residential DSL/Cable broadband connection, where most setups involve home Cable/DSL routers. While its relatively simple enough to come up with a script to ping the gateway every so often, parse the logs, and then produce a summary output, I'd like to know if there's something else more fancy available already.
Basically, what I'm asked most often is just a program that gives "proof" that their broadband connection was unavailable at some point in time (since the user complaints of intermittent/erratic connections often fall on deaf ears). I was thinking of something in the likes of MRTG, but I doubt there are many cheap DSL/Cable routers that have MRTG/SNMP support.
If not... Hmm, I'm wondering how feasible it would be to track Internet usage using a Mac or PC behind one of these routers and maybe write an app to do it.
