Raspberry exporter

Export Raspberry Pi metrics in Prometheus node_exporter's textfile format.

It can also be used with other ARM SOCs to simply export the CPU temperature.

Dependencies

• Prometheus (obviously)
• Node Exporter with textfile collector

Install

• copy raspberry_exporter to /usr/local/bin.
• copy prometheus-raspberry-exporter.service to /etc/systemd/system
• enable and start prometheus-raspberry-exporter

For example you can deploy using git:

cd /opt
sudo git clone https://github.com/prontog/prometheus-raspberry-exporter
cd prometheus-raspberry-exporter
sudo ln -s /opt/prometheus-raspberry-exporter/prometheus-raspberry-exporter.service /etc/systemd/system
sudo ln -s /opt/prometheus-raspberry-exporter/raspberry_exporter /usr/local/bin
sudo systemctl enable prometheus-raspberry-exporter
sudo systemctl start prometheus-raspberry-exporter

Configure your node exporter

Make sure your node exporter uses textfile in --collectors.enabled and add the following parameter: --collector.textfile.directory=/var/lib/node_exporter
