Getting started

To get the sample up and running you can follow these steps:

1. Clone the repository and install the dependencies

git clone autometrics-dev/gettingstarted-am-py

cd gettingstarted-am-py

pip install -r requirements.txt

2. Download the Autometrics CLI

If you're on macOS you can use Homebrew:

brew install autometrics-dev/tap/am

or you can grab the binaries directly from the GitHub release.

3. Start the application

python uvicorn main:app --reload

The application will start on a port 8080 by default and expose a metrics endpoint.

4. Start the Autometrics CLI and Explorer

Start the Autometrics CLI and point it to the endpoint it can scrape metrics from.

am start :8080

Autometrics CLI will download and run a Prometheus binary under the hood and start scraping metrics.

5. Preview the metrics in Autometrics Explorer

Autometrics CLI will also start a server with the Explorer available on localhost:6789. You can browse it and start exploring your sample app metrics! (You might need to ping the endpoints a few times to see the data reflected).

That's all!
