How to trace python exception of running service on VDS server?

Question

Python

I rented a mini-server, launched a telegram bot on it as a service, so that it would restart automatically if it crashes.
He fell down the first night and didn't get up. How can I see on the server what error caused it to stop working?
In the terminal, of course, there is nothing. the script is running as a service.

Answer 1

Use some kind of process manager, such as supervisord, which will keep logs and restart the fallen one.

Answer 2

so that it restarts automatically if it crashes

systemd and should have taken care of this if the appropriate setting is in the unit-config.

Answer 3
