# nvme-wdc-vs-temperature-stats(1)

Display temperature-related statistics

## NAME

nvme-wdc-vs-temperature-stats - Display temperature-related statistics

## SYNOPSIS

```
nvme [<global-options>] 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.

## OPTIONS

## GLOBAL OPTIONS

The following options are defined at the top-level nvme command and are available to this subcommand:

- \--dry-run

  Print the command that would be executed, but do not actually execute it.

- \--no-ioctl-probing

  Disable probing for 64-bit IOCTL support.

- \--no-retries

  Disable retry logic on transient errors.

- \-o \<fmt\>, --output-format=\<fmt\>

  Set the reporting format to *normal*, *tabular, 'json*, or *binary*. Only one output format may be used at a time.

- \--output-format-version=\<version\>

  Select the output format version. Version *1* uses the original field naming, while version *2* (default) provides more consistent and script-friendly field names. Other versions are rejected.

- \--quiet

  Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.

- \--set-options=\<key=value\>\[,\<key=value\>...\]

  Set libnvme library options for this invocation. Supported keys are *force-4k*, *mi-probe-enabled*, *test-base-dir* and *test-sysfs-dir*.

- \--timeout=\<ms\>

  Set the timeout for the command in milliseconds. *infinite* or *-1* waits without a time limit (0xffffffff).

- \-v, --verbose

  Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in [nvme-cli.conf(5)](/nvme-cli.conf/5.md). A command-line flag always overrides the file.

## EXAMPLES

• Displays the temperature stats for the device:

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

## NVME

Part of the nvme-user suite.
