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 customisable 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 dial-up 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 dial-up duration. The reports can be exported to a variety of formats, such as HTML, MS Word and Excel, for further analysis.
