[ceph-users] Nautilus Health Metrics

All; I turned on device health metrics in one of our Nautilus clusters. Unfortunately, it doesn't seem to be collecting any information. When I do "ceph device get-health-metrics <device>, I get the following; { "20200821-223626": { "dev": "/dev/sdc", "error": "smartctl failed", "nvme_smart_health_information_add_log_error": "nvme returned an error: sudo: exit status: 1", "nvme_smart_health_information_add_log_error_code": -22, "nvme_vendor": "samsung_ssd_860_evo_4tb", "smartctl_error_code": -22, "smartctl_output": "smartctl returned an error (1): stderr:\nsudo: exit status: 1\nstdout:\n" } } The cluster is Nautilus 14.2.16 (updated from 14.2.11 just after turning on health metrics). Smartctl is release 7.0 dated 2018-12-30 at 14:47:55 UTC. Thoughts? Thank you, Dominic L. Hilsbos, MBA Director - Information Technology Perform Air International Inc.
