April 15, 2025 - In this file, we import make_asgi_app from prometheus_client to create a Prometheus metrics app. We pass that registry to make_asgi_app() to create the metrics app. We mount that metrics app at the /metrics route using app.mount("/metrics", metrics_app). We start the server and navigate to localhost:8000/metrics. We should see the following response in our web browser. ... from fastapi import FastAPI, Request from prometheus_client import make_asgi_app, Counter app = FastAPI() index_counter = Counter('index_counter', 'Description of counter') metrics_app = make_asgi_app() app.mount("/metrics", metrics_app) @app.get("/") def index(): index_counter.inc() return "Hello, world!"

r/FastAPI on Reddit: FastAPI and Prometheus endpoint

December 16, 2022 -

Hi all,

I have a fastapi app which generates some custom prometheus metrics with the prometheus client library.

I can start a separate server with start_http_server method from the prometheus client, but i would like to have the /metrics endpoint be served on the same port as my fastapi app.

I cant seem to find an easy way to do this, i see a prometheus offers integration with ASGI but i cant figure out how to piece everything together. AAnyone here done this before?

You won't be able to start 2 servers/processes listening on the same port. First one to start, wins. The other will fail to bind as the port is already in use. What you could do though is start both on different ports, say 8080 and 8081 or something, then put nginx in front of it all and proxy through to which ever backend based on the requested path. As a bonus you can terminate TLS at the nginx level using a single cert etc etc too.

r/FastAPI on Reddit: Prometheus Middleware is out!

October 12, 2020 -

Today is pretty unusual day - my first Middleware for #FastApi (and, obviously, #starlette) is out. It deals with integration and customization metrics for #prometheus with, I hopefully, simple and intuitive way.

Working with #FastApi is delight and I hope this middleware will make life of couple of folks even easier :)

Will be happy with criticism and suggestions :)
