Cyber Bandwidth Monitor: Keep track of your bandwidth usage
Cyber Bandwidth Monitor does pretty much exactly what you'd expect it to do, and more. This little WIndows utility tracks your upload and download speeds over time and plots your network activity on a little graph. The utility grabs data once per second, but you can adjust the settings so that it refreshes more frequently. You can also tweak a ton of display settings, ranging from the font and window size to the graph scale.
In addition to real-time information, the program also logs all of your activity over time and can send you daily, weekly, or monthly updates. Cyber Bandwidth Monitor also has a few other useful features, like built in Ping and Traceroute utilities.
