Is there a way how to add metrics that are not dependent on request/response? about prometheus-fastapi-instrumentator HOT 2 CLOSED

Hi @trallnag , thanks a lot for reaching back that quickly!

I'll try to think of decoupling the problem from request/response workflow and see if any of the attempts would work.

The documentation for background task is available from here: https://fastapi.tiangolo.com/tutorial/background-tasks/ Let me know if I could provide you with some other use case.

Hey @lpravda, it sounds like this is not something that can be covered by this project. As you have pointed out it is really only usable for request/response workflows where the response represents the "end" of the task you are interested to instrument. So in your case I'd probably do the instrumentation myself either completely uncoupled from the FastAPI endpoint or extract path info from the request and use that info in combination with custom instrumentation

I wonder if there are other options / existing libraries available for this. But I cannot think of any. Maybe in the future OpenTelemetry initiative will this easy and many different small packages redundant.

Can you post an example or a link that shows using BackgroundTask? It is new to me
