rpi_exporter

A lightweight Prometheus exporter for Raspberry Pi hardware metrics.

Currently supports the following metrics from the VideoCore System-on-Chip:

• Component power states
• Clock rates
• Temperatures
• Voltages
• Turbo mode

rpi_exporter is written in Go, has no dependencies and does not rely on vcgencmd to query hardware stats. It interfaces directly with the VideoCore device so that metric-collection is as lightweight and fast as possible.
