Django integration on settings.py

[GeniusWiki]

My app is django+gunicorn+gevent. In gunicorn, it runs 9 processes.

I insert stackimpact.start() in settings.py. My app can start and data is coming as well. However, when I run command line, say, ./manage.py migrate, it stuck there can not exit. If I use keyboard ctrl-c to terminate, the error stack is:

^CException ignored in: <module 'threading' from '/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/threading.py'>

    t.join()

KeyboardInterrupt

As this migration is on our CI pipeline, we cannot manually to terminate it. How can I avoid that? What is the correct way use stackimpact with django?
