Fritz!Control

Fritz!Control allows you to monitor your FRITZ!Box devices, provided they export their signal data to /proc/avalanche. Basically, this does the same as the JavaScript code in the Web interface, but much better. It will provide you with a history so that you can see how high a carrier has gotten since you started monitoring. It also colors the bars relative to the delta to the maximum value, so you can easily spot where carriers are not stable. The tool has built in cursor functionality, so you can move over any carrier with your mouse and it will show the exact value in the status bar.
