I’ve been having problems with a flaky DSL connection from CenturyLink. My modem would frequently ‘retrain,’ that is, disconnect and reconnect the DSL session. This is rather annoying, and since I use VoIP for most phone calls when I’m at home, very irritating.
I wanted a method to log the modem’s statistics and see if I could find any correlation with the drops. One of the unfortunate realities with consumer level equipment is the lack of standard monitoring capabilities. Most enterprise level equipment support SNMP, which allows various software programs to request information.
