NVME-SNDK-VS-TEMP(1)

NAME
nvme-sndk-vs-temperature-stats - Display temperature-related statistics

SYNOPSIS

nvme [<global-options>] sndk 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 Sandisk 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.

--timeout=<ms>
    Set the timeout for the command in milliseconds.

-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). A command-line flag always overrides the file.

EXAMPLES

    • Displays the temperature stats for the device:

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