Expose raspberry PI metrics using Grafana and Prometheus:

Visualise your Raspberry PI metrics. Very easy installation - requires single command. Supports multiple Raspberries.

This project contains Ansible playbook which installs four services on Raspberry:

• Node exporter - exposes Raspberry metrics
• rpi_exporter - exposes CPU temperature as Prometheus metric
• Prometheus - collects and stores metrics
• Grafana - metrics visualization

• Raspberry PI with ARMv7/ARM x64 processor (Tested on Raspberry Pi 3 Model B+)
• Ubuntu Server installed on Raspberry (like Ubuntu Server 20.04 LTS)
• open port 22 on raspberry (SSH)
• open port 3000 on raspberry (Grafana)

Ansible is required for installation.

If you don't have Ansible installed, see Ansible installation.

Checkout project.

Edit file ansible/hosts and set Raspberry IP address in main-raspberry group.

If you have more than one Raspberry PI, configure additional Raspberry PI addresses in additional-raspberries group.

Here is the example:

The "main" Raspberry will have all 4 services installed (Prometheus, Node exporter, rpi_exporter and Grafana), and the "additional Raspberries" will have Node exporter and rpi_exporter service installed.

The main Raspberry will collect metrics from all additional Raspberries (if configured), so they must be accessible from the main Raspberry.

Run Ansible playbook with password authentication:

    cd ansible/
    ansible-playbook raspberry.yml -i hosts -u pi -D -k -K

Or run Ansible playbook with SSH keys authentication:

    cd ansible/
    ansible-playbook raspberry.yml -i hosts -u pi -D

• Go to Grafana URL http://raspberry:3000/
• login with admin/admin
• Click on "Raspberry metrics" dashboard:

• If you have more than one Raspberry configured, you can select another Raspberry using instance dropdown:
