I wanted to monitor my ISP’s service over time and could not find any available simple tool for that. The usual system monitoring tools are usually displaying averages, not min\/max values. So I used WD40 (speedtest-cli<\/a>) and duct tape (cron<\/a>) to make my own.<\/p>\n\n\n\n

You need to have a cron daemon set up and speedtest-cli<\/code> installed.<\/p>\n\n\n\n

Then prepare an empty csv file with a header like this (don’t forget a trailing newline!) and store it in a path of your choice:<\/p>\n\n\n\n

Server ID,Sponsor,Server Name,Timestamp,Distance,Ping,Download,Upload,Share,IP Address\n<\/code><\/pre>\n\n\n\n
Set up a cronjob at an interval of your choice (don’t be a dick) to run a speed test and log the results to the csv file:<\/p>\n\n\n\n
@hourly speedtest --csv >> \/home\/user\/path\/to\/speedtest.csv<\/code><\/pre>\n\n\n\n
If you have a fast connection you might spot slow test servers that would badly bias your results, so exclude them using the --exclude<\/code> option if necessary.<\/p>\n\n\n\n
That’s all, you get a nice log of internet ping, upload and download speeds, ready to be visualized in your software of choice (like the best spreadsheet software in existence<\/a>). I will have to complain to my ISP for that drop since mid December for sure:<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
And now that I have written this, I realise that for plotting I could also just use a min\/max function for a moving time window in Grafana<\/a> I guess? The speedtests would still be triggered and provide nice bursts of usage. Anyone got pointers on how to do that?<\/p>\n","protected":false},"excerpt":{"rendered":"
