Do you have 7.0+? That’s when JSON output was added for Ceph. Are your drives natively visible to the kernel, not hidden behind a RAID HBA?

Using 19.2.2, we notice under cluster/osds/'device health' on the dashboard, for all osds no matter the server:
Warning Smartctl has received an unknown argument (error code -22). You may be using an incompatible version of smartmontools. Version >= 7.0 of smartmontools is required to successfully retrieve data. That error code resolves to 'unknown attribute' in the smartctl docs. However, the same result occurs whether the drive is HGST, Seagate, or Western Digital.
"State of Health" is always "Stale"
"Life Expectancy" is always "n/a> 6 weeks"
Of course the 'diskprediction_local" module has been broken for over a year, as it requires a no-longer-distributed rev of a sub-package, but that shouldn't stop the smartctl command from normal operations.
Any ideas?
Thanks!
