Looking for a tool to perform internet/broadband speed testing in an automated/scheduled fashion for as long as I want, and be able to view a graph of the speed history. The speed test should be similar to what speedtest.net does, just with ability to do it at user-specified intervals and times (hourly, every two hours, daily, etc.) and log/graph the results. Seems basic enough but having trouble locating a good tool.
Have tried the 3 tools below but all have issues:
(download speed measurement way off)
(expensive just to add the unlimited scheduling function)
(trial allows only one speed test, which did not work, doesn't let me try again without paying. Also has bizarre interface)
