Hi Guys,

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
