Run sudo nvme smart-log /dev/nvme0 to print the drive's SMART health data.

01Command

Command

$ sudo nvme smart-log /dev/nvme0

02What it does

nvme-cli talks directly to the NVMe device and reports percentage-used, available spare, temperature and error counters, which let you predict wear before a drive fails. There is no GUI for headless servers, so this check belongs in monitoring scripts.
