Gunicorn instrumentation with statsd_host

[christian-2]

I would like to configure--statsd-host for Gunicorn instrumentation in tiangolo/uvicorn-gunicorn-fastapi:python3.7-alpine3.8. So far, I have not had success e.g. with echo "statsd_host = 'localhost:9125'" >> /gunicorn_conf.py in /apps/prestart.sh. Is there a better way to try this and is is possible at all?

You can probably pass it in GUNICORN_CMD_ARGS: https://github.com/tiangolo/uvicorn-gunicorn-fastapi-docker#gunicorn_cmd_args

Thanks for you response. I am now employing GUNICORN_CMD_ARGS="--statsd-host=localhost:9125 --statsd-prefix=service.app --log-level=debug". Gunicon logs this at startup:

logger_class: gunicorn.glogging.Logger
statsd_host: ('localhost', 9125)
statsd_prefix: service.app

So this looks good, also because it suggests that no custom logger is in play and interferes (benoitc/gunicorn#1187, benoitc/gunicorn#1405). But Gunicorn instrumentation is still not working e.g. in the sense that tcpdump does not reveal any traffic on port 9125. I am wondering what else I could be missing.

Hmm, I'm not really sure, I haven't used that. Maybe it would be best to first try with Gunicorn alone with a small independent app (say with Flask) and see how that works.

Then try with Gunicorn and Uvicorn.

And then try again inside Docker.
