It is possible to make supervisor logs to be in JSON format?

[Gelembjuk]

I have the app where the supervisor is used. It is the docker container. My app managed by the supervisor outputs logs in JSON format. But when i view logs of that container i also see logs of the supervisor itself and it is not JSON.

Can i control format of supervisor logs?

Now i have something like this

# docker run ftp-engine:2402

2024-02-05 08:34:22,992 INFO supervisord started with pid 19

any ay to change logs of supervisor to be same format as my app format?
