Observability for your Supabase project, using Prometheus/Grafana, collecting ~200 metrics:
To run the collector locally using Docker Compose:
Create an .env file:
cp .env.example .env
Fill it out with your project details.
- 
To monitor a single project, fill out your
project refandservice role key, which you can find here. - 
Alternatively, to monitor multiple projects you'll need to create an access token here.
 
After that, simply start docker compose and you will be able to access Grafana:
docker compose up
Visit localhost:8000 and login with the credentials:
- Username: 
admin - Password: [the password in your 
.envfile] 
Deploy this service to a server which is always running to continuously collect metrics for your Supabase project.
You can run the collector on a free instance of Fly.io
Follow these steps:
- Make sure you have the Fly CLI installed, and you are logged in.
 - Run 
fly launch --copy-configto deploy the app to Fly. - Copy your 
.envfile to your Fly project:fly secrets import < .env - After a successful deployment, your app will be available at 
https://<your-app-name>.fly.dev 
The process for collecting metrics off read replicas is currently somewhat manual. The prometheus.target.yml.tpl file can be edited to include the RRs as an independent target.
As an example, if the identifier for your read replica is foobarbaz-us-east-1-abcdef, you would insert the following snippet:
  - job_name: supabase-foobarbaz-us-east-1-abcdef
    scheme: https
    metrics_path: "/customer/v1/privileged/metrics"
    basic_auth:
      username: service_role
      password: __SUPABASE_SERVICE_ROLE_KEY__
    static_configs:
      - targets: ["foobarbaz-us-east-1-abcdef.supabase.co"]
        labels:
          - supabase_project_ref: "foobarbaz-us-east-1-abcdef"
