Python agent and FastAPI web framework

Read about the requirements and tips for integrating our Python agent with an app that uses the FastAPI web framework. To return to the general install instructions, go to Install the Python agent.

Automatic initialization with admin script

If you start your app with python app.py and use our Python agent version 5.22.0.151 or higher, you can use the recommended admin script integration method.

Here's an example using the admin script method:

NEW_RELIC_CONFIG_FILE=path/to/newrelic.ini newrelic-admin run-program [web server] path_to_app

Python agent API

You can use the Python agent API to monitor any ASGI server or framework. To do this, mark the ASGI application entry point and set the transaction names.

Event loop diagnostic support

Our Python agent supports asyncio event loop diagnostics. For more information, see Python event loop diagnostics. cs).
