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.
