Is there a way to log python print statements in gunicorn?

Question

With my Procfile like this:

web: gunicorn app:app \\
    --bind \"$HOST:$PORT\" \\
    --debug --error-logfile \"-\" \\
    --enable-stdio-inheritance \\
    --r         


        

Answer 1

Please try below command:

gunicorn --workers 3 --bind 127.0.0.1:5000 --error-logfile /var/log/gunicorn/error.log --access-logfile /var/log/gunicorn/access.log --capture-output --log-level debug

It did work for me.

Please specify log-level to debug(default info)http://docs.gunicorn.org/en/stable/settings.html#loglevel,

Also, specify capture-output flag (default false)http://docs.gunicorn.org/en/stable/settings.html#capture-output.

You should be able to watch logs in error log file.
