As I’ve previously stated I’m no longer using Virgin Media but when I was I had written a script to scrape statistics from the cable modem and import them into collectd. Primarily I was recording the upstream/downstream line speed and the per channel signal figures, but they could easily be extended to do more if you wanted. Useful to see when Virgin increase your line speed, or see if your line quality has deteriorated. I’ve shoved the versions I had for the Super Hub v1 and v3 in GitHub in the hope they’ll be of use to someone. Note that I posted my SuperHub 3 back to Virgin yesterday so I no longer have any hardware that needs these scripts.
