How to export metrics on a different port about prometheus-fastapi-instrumentator

[trallnag]

If you want to do that don't use the provided expose method. Just instrument the API and expose the metrics endpoint yourself for example like this:

from prometheus_client import start_http_server

start_http_server(8000)

Hi @VMAtm, I can't reproduce your issue. Here is the example I tried: https://github.com/trallnag/prometheus-fastapi-instrumentator/tree/example-different-port/devel/examples/metrics-diff-port-uvicorn

Hi, sorry for bringing this old issue up.
Is there any example of start_http_server on a dedicated port?
I'm using FastAPI with uvicorn, and I want to export the metrics on a different port. I call start_http_server, but I never get any answer from that endpoint.
Is there any complete example of how this can be done?

Thanks 👍

So default port will also work alongwith this port?

Not 100 % sure what you mean, but I would say yes 😄

I'll check on my side, thank you for the fast example!
