Intermapper probe for Comtrend DSL modem

I wanted to keep track of the Signal to Noise Ratio (SNR) for my DSL modem. I was losing connections overnight, and wanted to prove to my ISP that this was happening.

Intermapper now monitors and plots the SNR continually, so it's easy to see dips in the signal quality, and the times they occur. This helped my ISP figure out what was happening.

The Probe

This probe demonstrates a detailed InterMapper command-line probe, using the IMDC Python interpreter.

This probe connects to a Comtrend DSL modem's web interface, and retrieves its SNR values and uptime values. This has been tested with a Comtrend AR-5381U modem. Here's the Status Window:
