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

DITT support status

0 = unsupported

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.

+
+
+
+
