Is there a way to log python print statements in gunicorn?
With my Procfile like this:
web: gunicorn app:app
--bind "$HOST:$PORT"
--debug --error-logfile "-"
--enable-stdio-inheritance
--reload
--log-level "debug"
is it in any way possible to get python print statements to be logged to stdout / bash? I am using the bottle framework here as well, if that affects anything.

The debug flag doesn't apply to gunicorn. It actually fails if you try to run it:gunicorn: error: unrecognized arguments: --debug

It turns out the print statements were actually getting through, but with delay.
The gunicorn docs for --enable-stdio-inheritance note to set the PYTHONUNBUFFERED, which I thought I had, but it seems with wrong syntax.
I solved it using a .env file with my foreman setup to set the variable like this:
PYTHONUNBUFFERED=TRUE

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 info
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.

In python 3, adding flush=True in each print statement works for my flask/gunicorn app.
E.g.
gunicorn --bind 0.0.0.0:8080 server --log-level debug
No particular flags are required.

The debug flag doesn't apply to gunicorn. It actually fails if you try to run it:
