start_http_server with make_asgi_app?

[mecampbellsoup]

Hi guys,

Quick question and hopefully not a dumb one but, nevertheless:

start_http_server only works with make_wsgi_app - is there anything preventing one from doing something similar with make_asgi_app instead?

An alternative is to install prometheus-async which has its own start_http_server.

We have a FastAPI + uvicorn (ASGI) application and are looking to expose some Prometheus metrics for export.

from fastapi import FastAPI
import prometheus_client

app = FastAPI()
metrics_app = prometheus_client.make_asgi_app()
app.mount("/metrics", metrics_app)
