how to enable prometheus custom metrics for Django backend process (realtime kafka consumer) and access web endpoint

Question

I have django app for kafka consumer which consumed realtime events and I have added custom prometheus metrics to track consumed events but when my app is running i don't see custom metrics at the web endpoint /metrics. I am getting 504 gateway timeout error because my consumer is running in the background and no response gets send out. I tried with Django health check but its the same issue.

I tried running my consumer using Django custom management command, but then web endpoint didn't work.

So is there a way to run consumer app in background and exposed prometheus metrics and access web endpoint
