I want to track/monitor/log our home broadband usage, specifically I want to track where the quota is being used e.g. sites, services. I can get usage meters from our ISP (Internode) but these only show an aggregate of how much we've used.
I've looked at tools like bandwidthd and cacti and have installed bandwidth to see what it can show me.
Is there anything I can install onto my linux server that watch and log what we use when?
A squid proxy can be useful for this, but obviously only for http/https traffic, and proxying isn't without its problems. Otherwise, 'netflow' is a useful keyword to use when googling. Of course all of this relies on either your linux server being the router (or in a position to intercept all traffic), or your router supporting the export of netflow data to your server for processing.
