How to use Django logging with gunicorn

Question

I have a Django 1.6 site running with gunicorn, managed by supervisor. During tests and runserver I have logging on the console, but with gunicorn the statements don\'t show up

Answer 1

First, in your supervisor config for the gunicorn script, be sure to define

stdout_logfile=/path/to/logfile.log
redirect_stderr=true

That will make stdout and stderr go to the same file.
Now, on your gunicorn script, be sure to call the process with the following argument

gunicorn YourWSGIModule:app --log-level=critical

Answer 2

In /etc/supervisor/conf.d/your-app.confyou should set log paths:

stdout_logfile=/var/log/your-app.log
stderr_logfile=/var/log/your-app.log

Answer 3

I got a response on GitHub:

Since you have passed disable_existing_loggers the Gunicorn loggers are disabled when Django loads your logging configuration. If you are setting this because you want to disable some default Django logging configuration, make sure you add back the gunicorn loggers, gunicorn.error and gunicorn.access with whatever handlers you want.
