I’m going to cheat a little today and pretty much just post you what the NetWorx site says as is does a great job of explaining exactly what the software does.
"NetWorx is a simple and free, yet powerful tool that helps you objectively evaluate your bandwidth situation. You can use it to collect bandwidth usage data and measure the speed of your Internet or any other network connection. NetWorx can help you identify possible sources of network problems, ensure that you do not exceed the bandwidth limits specified by your ISP, or track down suspicious network activity characteristic of Trojan horses and hacker attacks.
"The program allows you to monitor all your network connections or a specific network connection (such as Ethernet or PPP) only. The software also features a system of highly customizable visual and sound alerts. You can set it up to alert you when the network connection is down or when some suspicious activity, such as unusually heavy data flow, occurs. It can also automatically disconnect all dialup connections and shut down the system.
"The incoming and outgoing traffic is represented on a line chart and logged to a file, so that you can always view statistics about your daily, weekly and monthly bandwidth usage and dialup duration. The reports can be exported to a variety of formats, such as HTML, MS Word and Excel, for further analysis."
The only problem is that this doesn’t track across multiple computers, just on single computers. To track multiple computers you’d need to see if your router does that or if that feature can be added to your router.
