NVME-WDC-VS-TEMPE(1)

💖 nvme-wdc-vs-temperature-stats(1) — the NVME-WDC-VS-TEMPE girlies' edition 💖

okay so bestie, welcome to the NVME-WDC-VS-TEMPE(1) page from the NVMe manual 🎀 — yes that's the whole vibe, let's get into it ✨

---

🌡️ NAME 🌡️

nvme-wdc-vs-temperature-stats — literally just "Display temperature-related statistics". That's it. That's the whole gig 💅

---

🦋 SYNOPSIS 🦋

nvme [<global-options>] wdc vs-temperature-stats <device>

---

✨ DESCRIPTION ✨

So for the NVMe device you hand it, it displays temperature statistics. Simple slay 🫶

The <device> parameter is mandatory — it's an NVMe character device, like /dev/nvme0 for example 🎀

⚠️ ngl this will only work on WDC devices that actually support this feature. Results for any other device are undefined — like, we don't know what happens, and you don't wanna find out bestie 😭

Expected status and 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. periodt 👑

👑 OPTIONS 👑

🌈 GLOBAL OPTIONS 🌈

These options are defined at the top-level nvme command and are available to this subcommand — so yes, they're shared, we love a communal vibe 🫶

• --dry-run — Print the command that would be executed, but do not actually execute it. All the fakes, none of the commitment 🙈
• --no-ioctl-probing — Disable probing for 64-bit IOCTL support.
• --no-retries — Disable retry logic on transient errors. One shot, no takebacks 💀
• -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 — CLI stays main character energy 👑

💜 EXAMPLES 💜

• Displays the temperature stats for the device:

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