Package: prometheus-disk-exporter
prometheus-disk-exporterA prometheus exporter for disk S.M.A.R.T. data and partition usageinformationFor security reasons, this script isnotsupposed to be ran with root
privileges. Instead, the only command which requires these privileges
(smartctl) is ran usingsudowithingetter.sh. For this reason
the installation step includes adding a sudoers configuration to run
this command without the need of a password for the specified user.installingThese steps assume that you are running with root privileges.Setup prometheus userNote: this step can be skipped if you already have a linux user

if all you are looking for is a SMART data exporter, i highly recommend their
implementationproxmox prometheus metrics,
for helping me figure out how to properly install the package
