This smells like a munin or smokeping plugin (or some other sort of monitoring) gathering data for graphing. I have wanted something like this to graph bandwidth, latency, packet loss over time. If we could come up with a lighter weight way of doing this (or using a speedtest.net type service) that would be nice to have. I recently went from having a comcast cable modem where the bottleneck was in the modem, to a centurylink gig fiber where my bandwidth depends on what the neighbors are doing, which makes tuning SQM difficult... Thus my desire to start monitoring things. -- Matt Taggart matt@lackof.org
