OSX SMC Exporter

A prometheus exporter for the OSX SMC (System Management Controller) sensors for fan speed and CPU temperature.

The heavy lifting required to extract the relevant sensor readings is handled by the smcFanControl CLI. This application just parses the output and exposes it as prometheus metrics.

Notes

• The binary smc cli is checked into this repo. The version of the cli is based on this PR
• The server uses Graal native image to create a single executable (that includes the smc command) that you can just run.
