Automated docker speedtest analyser tool with included web interface to monitor your internet speed connection over time. Setup at home on your NAS (Synology, QNAP tested) and the container runs hourly speedtests. The speedtest results are displayed in an webinterface as line graph(s) over the day.
Not the most elegant means, but I hacked this together to get averages for my own setup and figured it was worth sharing.
Feel free to adapt, change or dismiss as you see fit :)
