You can adjust the transparency level of the output window or move Netmeter into the system tray. You can also adjust the colors of the graph if you like, the default colors have a nice contrast though.

The most important feature of Netmeter is however not information about the current network traffic but the statistics that it accumulates over time. In short, it displays totals for the day, week and month as well as projected figures for the same periods.

It also displays the peak upload and download which is the maximum amount of bandwidth that your connection was capable of. This can be used to analyze the download and upload limit of your connection. Helpful if your provider sold you a 16 Mbit connection but you only get speeds of 2 Mbit. Just make sure you use to download and upload data from a server that is capable of sending data in your maximum speeds. You could alternatively just keep it running in the background to check on the stats in regular intervals.

Netmeter has an alert function that warns you when you reach a defined amount of gigabytes during a day, week or month. This is probably the best feature for users with limited bandwidth accounts making sure that you do not have to pay additional fees to your provider because you went over your bandwidth limit.

Best of all it is free to use and does not use many resources. Available only for Microsoft Windows.
