After waiting if something came up, I have zipped everything together and made a small howto.(borrowed and adjusted).

Using ADSL Log you are able to note how much traffic there has been on your internetconnection. This can bee seen in various graphical ways (have a look at my traffic for an example, or click at the left hand side on the module "ADSL Log").
It's nice to know how much internet traffic you have.
I have borrowed most of this from Bali, there is a download version available there also (version 1.0) , but it's not the same one you see in action on that website. My addjustments have made my version almost the same as the one that you see in action there.

It's easy adjustable to monitor the traffic on a specific networkinterface card.

It needs linux as operating system.
