nvme-sndk-vs-temperature-stats1
Display temperature-related statistics
Usage
nvme [<global-options>]
sndk
vs-temperature-stats
<device>
Overview
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. 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). A command-line flag always overrides the file.
Examples
• Displays the temperature stats for the device:
# nvme sndk vs-temperature-stats /dev/nvme0
Nvme
Part of the nvme-user suite.
