Balena Application plugin for Grafana

Introduction

The Balena Application plugin for Grafana allows to display device information and manage services using Balena Supervisor API.

Requirements

• Grafana 8.5+, Grafana 9.0+ is required.

Getting Started

The Balena application is under development and not included in the Grafana Marketplace yet. It can be installed manually from our private repository or downloaded directly from the GitHub repository:

grafana-cli --repo https://volkovlabs.io/plugins plugins install volkovlabs-balena-app

balenaCloud

Our custom Grafana build with the Balena Application plugin can be deployed directly to balenaCloud:

We recommend to add it to your docker-compose.yml together with NGINX reverse proxy (example configuration in the repository):

version: '2.1'

services:
  grafana:
    image: ghcr.io/volkovlabs/balena-app:latest
    network_mode: host
    restart: always
    labels:
      io.balena.features.supervisor-api: '1'
    volumes:
      - grafana-data:/var/lib/grafana

  nginx:
    build:
      context: ./nginx
      dockerfile: Dockerfile
    network_mode: host
    restart: always
    depends_on:
      - grafana

volumes:
  grafana-data:

Default Grafana username and password is admin/admin.

You can learn more about balena Labels in the Documentation.

Features

• Allows to display device, release information and service logs using Balena Supervisor API.
• Provides Services Panel to start, stop, restart Containers.
• Allows to filter Logs using Regex pattern.
• Requires Confirmation to restart all Services and reboot the device.

Balena Supervisor

The balena Supervisor is balena's agent that runs on devices. Its main role is to ensure your app is running, and keep communications with the balenaCloud API server.

The Supervisor has its own set of APIs providing means for services to communicate and execute some special actions that affect the host OS or the services itself.

Provisioning

Grafana supports managing data sources by adding one or more YAML config files in the provisioning/datasources folder.

Example of provisioning the Balena Supervisor Data Source.

datasources:
  - name: API
    type: volkovlabs-balenasupervisor-datasource
    uid: P9E471951A1B4106C
    jsonData:
      url: ${BALENA_SUPERVISOR_ADDRESS}
    secureJsonData:
      apiKey: ${BALENA_SUPERVISOR_API_KEY}
