NVME-WDC-VS-TEMPE(1)		  NVMe Manual		  NVME-WDC-VS-TEMPE(1)

NAME
       nvme-wdc-vs-temperature-stats - Display temperature-related statistics

SYNOPSIS
       nvme wdc	vs-temperature-stats <device>

DESCRIPTION
       For the NVMe device given, displays temperature statistics.

       The <device> parameter is mandatory NVMe	character device (ex:
       /dev/nvme0).

       This will only work on WDC devices supporting this feature. Results for
       any other device	are undefined.
