Prometheus Raspberry Pi Exporter

Export Raspberry Pi metrics in Prometheus node-exporter's textfile format.

To visualizate it you can use preconfigured Grafana dashboard.

Also you can use prepared Alert rules for Prometheus.

Install

sudo curl -o /usr/local/bin/rpi_exporter https://raw.githubusercontent.com/urpylka/prometheus-raspberry-exporter/master/rpi_exporter
sudo curl -o /etc/systemd/system/rpi_exporter.service https://raw.githubusercontent.com/urpylka/prometheus-raspberry-exporter/master/rpi_exporter.service
sudo chmod +x /usr/local/bin/rpi_exporter
sudo systemctl enable rpi_exporter
sudo systemctl start rpi_exporter

To run node-exporter use:

docker run -d -p 9100:9100 --pid="host" --name=node_exporter -v "/:/host:ro,rslave" --restart=unless-stopped prom/node-exporter --path.rootfs=/host --collector.textfile.directory=/host/var/lib/node_exporter/textfile_collector

To uninstall use:

sudo systemctl stop rpi_exporter
sudo systemctl disable rpi_exporter
sudo rm /etc/systemd/system/rpi_exporter.service
sudo rm /usr/local/bin/rpi_exporter

Configure your node-exporter

1. Make sure your node-exporter uses textfile in --collectors.enabled
2. Add the following parameter --collector.textfile.directory=/var/lib/node_exporter
