💅 NVME-SOLIDIGM-LATE(1) — the nvme manual, bestie edition ✨

okay so this is a page from the NVMe Manual, and honestly? it's a whole vibe. sit down, grab a strawberry 🍓, and let's get into it.

✨ NAME ✨

nvme-solidigm-latency-tracking-log — turn the Latency tracking Log on, or go grab it. that's the whole job, bestie 🎀

🌸 SYNOPSIS 🌸

nvme [<global-options>] solidigm latency-tracking-log <device>
                        [--enable | -e]
                        [--disable | -d]
                        [--read | -r]
                        [--write | -w]
                        [--type <value> | -t <value>]

look at her. iconic structure. main character energy fr fr 👑

💖 DESCRIPTION 💖

so what does it actually do? it enables, disables, or retrieves the Solidigm latency tracking log for whatever NVMe device you point it at. and this log? it's giving detailed information about I/O latencies. very demure, very data. ✨

the <device> parameter is mandatory — no cap, you literally cannot skip it. it can be either:

  • the NVMe character device (ex: /dev/nvme0), or
  • a namespace block device (ex: /dev/nvme0n1)

pick your fighter, both slay 🫶

🦋 OPTIONS 🦋

  • -e, --enable — enables latency tracking before you retrieve the log. turn it on first, bestie.
  • -d, --disable — disables latency tracking after you retrieve the log. clean up after yourself 💅
  • -r, --read — pulls the read latency statistics. also the default if you specify neither --read nor --write — so if you're indecisive, the universe (and this tool) picks read for you.
  • -w, --write — pulls the write latency statistics instead. writer girlies rise 🌈
  • -t <value>, --type <value> — specify which log type to retrieve. the valid values depend on what your device's capabilities are — so like, check with your device first, iykyk.

👑 GLOBAL OPTIONS 👑

these ones live at the top-level nvme command, and they're available to this subcommand too. the nepo babies of the option world, we love them:

  • --dry-run — prints the command that would be executed, but doesn't actually execute it. a dress rehearsal, basically. no commitment, just vibes 🎀
  • --no-ioctl-probing — disables probing for 64-bit IOCTL support.
  • --no-retries — disables retry logic on transient errors. one shot, no second chances 💀
  • -o <fmt>, --output-format=<fmt> — sets the reporting format to normal, tabular, 'json, or binary. only one output format may be used at a time — don't be greedy.
  • --output-format-version=<version> — selects the output format version. version 1 uses the original field naming, while version 2 (default) gives you more consistent and script-friendly field names. other versions? straight-up rejected. not on the list, not invited 🙈
  • --quiet — suppresses informational messages. errors are still reported, and --quiet cancels any --verbose for the library log level. quiet girl era, but the errors still get to speak.
  • --set-options=<key=value>[,<key=value>...] — sets libnvme library options for this invocation. the supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
  • --timeout=<ms> — sets the timeout for the command, in milliseconds. infinite or -1 waits without a time limit (0xffffffff). patience is a virtue, allegedly ⭐
  • -v, --verbose — increases the level of detail in the output. you can specify it multiple times to crank the verbosity even higher. louder. LOUDER. 🔥
also, tiny detail that matters: these options can be set as machine-wide defaults in nvme-cli.conf(5), and a command-line flag always overrides the file. CLI stays the main character 💜

🌈 EXAMPLES 🌈

enable latency tracking and retrieve the read latency log — the classic combo:

# nvme solidigm latency-tracking-log /dev/nvme0 --enable --read

retrieve the write latency log in JSON format — for the script girlies:

# nvme solidigm latency-tracking-log /dev/nvme0 --write -o json

disable latency tracking after retrieving the log — tidy queen behavior:

# nvme solidigm latency-tracking-log /dev/nvme0 --disable

specify a log type when retrieving latency statistics:

# nvme solidigm latency-tracking-log /dev/nvme0 --type 1 --read
