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.
