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
