I had to roll an upstream version of the smartmon tools because everything with redhat 7/8 was too old to support the json option. -- Paul Mezzanini Sr Systems Administrator / Engineer, Research Computing Information & Technology Services Finance & Administration Rochester Institute of Technology o:(585) 475-3245 | pfmeec(a)rit.edu CONFIDENTIALITY NOTE: The information transmitted, including attachments, is intended only for the person(s) or entity to which it is addressed and may contain confidential and/or privileged material.

The disk is SAS HDD, why those keywords with "nvme_" prefix? Is the same keywords used for all types of disk? Where can I see the command line options for running smartctl? Thanks!
