Prometheus smart exporter
From wikinotes
smartctl HDD info exposed to prometheus.
Unfortunately, it depends on systemd.
NOTE:
Don't use this, use a cron job to dump metrics for node_exporter
WARNING:
This is safer than smartctl_exporter.
A helper that runs as root runs smartctl, and the exporter runs as a non-privileged user.
Unfortunately it depends on systemd for some fancy background processing.
I think this could be simplified and made more portable by dumping to files.
I may write my own exporter.
