Run Speed Test Regularly and Chart Results

My ISP (comcast) is *perfect* and of course they never have network slow-downs when everyone starts streaming Netflix at 9 pm. So, yeah, I'd like to be able to optionally configure the speed test to run every hour and have the chart over a period of a few days or weeks so I can confirm what I already know...which is that the current infrastructure is fine when hardly anyone is using it but does downhill rapidly when everyone comes home and starts streaming. So, to summarize, I would like to be able to configure the speed test to run more often than once a day and then I would like those results to be kept for say 1 month so I can see hourly historical trends. Cool - thanks.
