Grafana provisioned for CarConnectivity Software

This image provisions Grafana with the following:

• Datasource to connect to PostgreSQL database with data from the car (Works with CarConnectivity-plugin-database)
• Datasource to obtain live data from the vehicle through CarConnectivity WebUI (Works with CarConnectivity-plugin-webui)
• Dashboards visualizing the data

More information

More information can be found on Github: https://github.com/tillsteinbach/CarConnectivity-grafana/

Requirements

• Docker 20.10.10 or later (if you are new to Docker, see Installing Docker and Docker Compose or for Raspberry Pi), docker-compose needs to be at least version 1.27.0 (you can check with docker compose --version)
• A Machine that's always on, so VWsFriend can continually fetch data
• External internet access, to talk to the servers

How to start

• Clone or download the files docker-compose.yml and .env
• To create myconfig.env copy .env file and make changes according to your needs
• create your carconnectivity.json configuration file as described in the CarConnectivity repository. The minimal viable configuration for carconenctivity with grafana is:

{
    "carConnectivity": {
        "log_level": "error", // set the global log level, you can set individual log levels in the connectors and plugins
        "connectors": [
            {
                // Definition for your connector
                ...
            }
        ],
        "plugins": [
            {
                "type": "webui",
                "config": {
                    "username": "admin",
                    "password": "secret",
                }
            },{
                "type": "database",
                "config":{
                    "db_url": "postgresql://admin:secret@postgresdbbackend:5432/carconnectivity"
                }
            }
        ]
    }
}

Webui username and password must match the values in your .env file. db_url must match your database configuration in the .env file.

• Start the stack using your configuration.

docker compose --env-file ./myconfig.env up

• Open a browser to use the webinterface on http://IP-ADDRESS:4000
• Open a browser to use grafana on http://IP-ADDRESS:3000 with the user and password you selected
