BWMeter is a powerful application designed for measuring your bandwidth speed and creating statistics and logs. The application is quite complex, so it is recommended that you know your way around your network settings.

Once you've started it, the application will run in the background. Basically, this application accurately measures your traffic in real-time and displays it in two graphs: one graph will display your LAN traffic while the other will display Internet traffic. Besides, the program will create hourly, daily, weekly, monthly and yearly detailed statistics regarding all traffic. You can manually add/remove IPs from your local network, including entire IP classes.

In order to get only the data you're interested in, you can set various filters (destination, protocol, port, scheduler, etc.) and you can even control your traffic. This means that you can stop the traffic in case your download/upload speed limit exceeds certain peaks. There's also a stopwatch included for traffic monitoring.

Besides monitoring local traffic, you can use the application to monitor traffic on remote machines. Statistics can be exported and imported in CSV format. A very useful option is the possibility to set alerts when the traffic reaches certain peaks. You can set the program to play sounds, display a message, send an email or even shut down the computer.
