Exploring this GREAT tool, thanks for the work you put into it!

I've an RPI 4 set to use Ookla speedtest and one RPI 4 set to use speedtest-cli.

The speedtest-cli logs look like this: 2020-06-19 10:35:02,332 test_network INFO:Testing Internet speed... 2020-06-19 10:35:32,835 test_network INFO:Successful speedtest. 2020-06-19 10:40:01,742 test_network INFO:Testing interface if-w 2020-06-19 10:40:13,083 test_network INFO:Successful iperf3 test. 2020-06-19 10:40:22,452 test_network INFO:Testing name resolution... 2020-06-19 10:40:22,508 test_network INFO:Internal DNS ok. 2020-06-19 10:40:22,560 test_network INFO:External DNS ok.

But the Ookla speedtest logs look like this: 2020-06-19 10:40:02,228 test_network INFO:Testing interface if-wlan 2020-06-19 10:40:02,229 test_network INFO:Testing interface if-wlan 2020-06-19 10:40:02,362 test_network INFO:iperf3 test failed. 2020-06-19 10:40:02,371 test_network INFO:iperf3 test failed. 2020-06-19 10:40:02,659 test_network INFO:Testing name resolution... 2020-06-19 10:40:02,669 test_network INFO:Testing name resolution... 2020-06-19 10:40:02,717 test_network INFO:Internal DNS ok. 2020-06-19 10:40:02,725 test_network INFO:Internal DNS ok. 2020-06-19 10:40:02,773 test_network INFO:External DNS ok. 2020-06-19 10:40:02,780 test_network INFO:External DNS ok.

The double log lines are just one symptom, the other is that the Internet testing for speedtest-cli are fairly smooth from point to point, but the Ookla graphs are very spiky, essentially every other test 'fails' with zero speed.

I installed the project step by step from the Wiki and updated the OS as suggested. Might there have been a new library introduced or???

Please post the output of the following two commands (run them on the RPi that is using the Ookla Speedtest CLI): sudo runuser -l pi -c "crontab -l" sudo runuser -l root -c "crontab -l"

Thanks, Chris

Silly me, added them twice. I've removed the lines from 'root's crontab and expect to see better results. Thanks for your quick response and resolution. Very much appreciated and I have been looking for exactly this function on my home network for a LONG time.
