​
Setup

Start AppSignal and define your Starlette application. Then use the StarletteInstrumentor to instrument your Starlette application: 
# app.py
from starlette.applications import Starlette
from opentelemetry.instrumentation.starlette import StarletteInstrumentor

import appsignal
appsignal.start()

# ... your application's code goes here ...

app = Starlette(
  # ...
)

StarletteInstrumentor().instrument_app(app)
