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.

Expected status and description :-
Statistic | Description
The current composite temperature | device temperature
Warning Composite TEMPerature threshold | temp of overheating
Critical Composite TEMPerature threshold | temp of critical overheating
Device Initiated Thermal Throttling support status | 0 = unsupported, 1 = supported
Host Controlled Thermal Management support | 0 = unsupported, 1 = supported
Thermal Management Temperature 1 (Light throttle) | temp to start light throttle
Thermal Management Temperature 1 Transition Counter | # times switched into light throttle
Thermal Management Temperature 1 Total Time | # seconds spent in light throttle
Thermal Management Temperature 2 (Heavy throttle) | temp to start heavy throttle
Thermal Management Temperature 2 Transition Counter | # times switched into heavy throttle
Thermal Management Temperature 2 Total Time | # seconds spent in heavy throttle
Thermal Shutdown Threshold | temp of device shutdown

On success it returns 0, error code otherwise.

EXAMPLES

    • Displays the temperature stats for the device:

        # nvme wdc vs-temperature-stats /dev/nvme0
