Thanks, and sorry that nobody took a look at the PR! Could you rebase it on top of the latest main, where the docs files now live under docs/... instead of content/docs/...?

About the metrics: would be nice to add some unit suffixes, where applicable. For example, for fan speed (_rpm?) and temperature metrics (_celsius I guess?), and I guess power would be in Watts, etc. See also https://prometheus.io/docs/practices/naming/
