I have the following code
#!/usr/bin/python3.8 import subprocess import requests import datetime import urllib3 urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) print("============================================================="); now = datetime.datetime.now() print(now); # speedtest --single --json speedout = subprocess.run(['speedtest', '--single', '--json'], stdout=subprocess.PIPE).stdout.decode('utf-8'); print("speedtest output:"+speedout); now = datetime.datetime.now() print(now); print("============================================================="); When I run it manually, it generates the following log
============================================================= 2021-04-26 12:23:14.869085 speedtest output:{"download": 48332978.441761896, "upload": 21216098.81470209, "ping": 43.796, "server": {"url": "", "lat": "-17.7450", "lon": "-48.6250", "name": "Caldas Novas", "country": "Brazil", "cc": "BR", "sponsor": "Hot Caldas Internet", "id": "40200", "host": "hotcaldas.lampinc.com.br:8080", "d": 230.63111881620188, "latency": 43.796}, "timestamp": "2021-04-26T15:23:15.343030Z", "bytes_sent": 26738688, "bytes_received": 60631816, "share": null, "client": {"ip": "179.xxx.xxx.14", "lat": "-1xxx", "lon": "-4xxx", "isp": "Vivo", "isprating": "3.7", "rating": "0", "ispdlavg": "0", "ispulavg": "0", "loggedin": "0", "country": "BR"}} 2021-04-26 12:23:39.011183 ============================================================= But when I place it on crontab (under my account) to run hourly:
0 * * * * /myscripts/monitors/speedtest.py >> /mylogs/speedtest.log 2>&1 it generates the following log

What could be happening?
Update. I added flush=True to all prints. It worked once but is failing again. Now the error msg changed
============================================================= 2021-04-26 16:00:01.943727 ERROR: Unable to connect to servers to test latency. speedtest output: 2021-04-26 16:00:03.616226 ============================================================= 1 Answer
I had the same problem before. I set cron to execute every 15 minutes and every task at xx:00 and xx:30 failed. Maybe speedtest has internal server problem.
So a solution to this problem is to avoid specific time. Please try something like this.
5 * * * * /myscripts/monitors/speedtest.py >> /mylogs/speedtest.log 2>&1
