Tracking bandwidth usage
I run a small little webhosting company that's starting to grow and I have a question regarding tracking the bandwidth usage of customers.
I basically need to track bandwidth generated from: email and web traffic.
Does anybody know how I would go about doing this? Are there apps that will sniff the traffic from my main router and read the headers, etc to track/log bandwidth? Can MRTG be used in some fashion?
Essentially I have: dedicated servers, shared virtual servers, and I have multiple email servers.
I'm using a Microsoft environment (windows server 2003, IIS, etc)
thanks in advance
