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.
