mi-router-4-exporter

Reads Google Fit from the API and exports it in a Prometheus format.

How does it work?

• It fetches the data from the Google Fit API ...
• ... parses it ...
• ... and exposes it in a format that Prometheus can consume.

How to run it?

1. Get a Google application (see here; https://developers.google.com/fit/rest/v1/get-started)
2. Set its redirect URL to https://localhost
3. Clone the repo and cd there
4. Create the .env file in the root folderet the CLIENT_ID, CLIENT_SECRET and REDIRECT_URL from the Google app
5. Run npm install
6. Run node authorize.js and follow the instructions.
7. You are authorized now, you should have the ./tokens/tokens.js file with authhorization tokens.
8. Build the container:

docker build -t fit-exporter .

3. Run the container (for configuration, see below):

docker run -it \
    -d --name=fit-exporter \
    -e PASSWORD=<insert your admin password here> \
    -p 3031:3031 \
    --label com.centurylinklabs.watchtower.enable=false \ # so it won't be restarter by Watchtower if it's running
    --restart unless-stopped \ # so it would start together with the system
    -v $(pwd)/tokens:/usr/src/app/tokens
    fit-exporter

4. Open http://localhost:3031/metrics in browser, it should display metrics.
5. If there were errors, check out the container logs.
