Can I send metrics to existing web server, instead of starting separate server (start_http_server)

[29swastik]

I've a python file running KafkaConsumer in infinite loop, there I want to increment prometheus counter whenever there is a failure while processing the consumed kafka message.

Here I don't want run start_http_server because I already have one fastapi server running and I want to send my counter metric to that fastapi server instead of running separate start_http_server, how can I do that?

It seems that some prometheus exporters exists for Starlette based apps (such as FastAPI) like https://github.com/stephenhillier/starlette_exporter

But I'm also wondering if the official prometheus python client could provide an exporter instead of starting a distinct http server 🙏
