NVME-WDC-GET-LATE(1)
π NVME-WDC-GET-LATENCY-MONITOR-LOG π
okay bestie, so this one lives in the NVMe manual β it's nvme-wdc-get-latency-monitor-log, and it's here to Display latency monitor log page data in human readable format. yes, the whole vibe is "make the numbers make sense" β¨
πΈ SYNOPSIS πΈ
nvme [<global-options>] wdc get-latency-monitor-log <device>
that's it. that's the whole incantation. πͺ
π¦ DESCRIPTION π¦
So for the NVMe device you hand it, it prints out latency monitor log page data. that's the job. she's straightforward. π
The <device> parameter is mandatory and it's gotta be an NVMe character device (ex: /dev/nvme0). no device, no log. sorry bestie, them's the rules π
β¨ real talk though: this will only work on WDC devices</> that actually support this log page. Results for any other device are undefined β like, we're not saying your random drive will explode, but we're also not saying it won't. don't come for me. π
On success it returns 0, and an error code otherwise. slay π
π OPTIONS π
β¨ GLOBAL OPTIONS β¨
these are defined up at the top-level nvme command, but they're available to this subcommand too β like the cool older siblings that still let you sit with them π«Ά
--dry-runβ prints the command it would execute, but doesn't actually execute it. it's giving "manifesting without committing". π--no-ioctl-probingβ disables probing for 64-bit IOCTL support. sometimes you just know, y'know? π--no-retriesβ turns off retry logic on transient errors. one shot, one opportunity. π₯-o <fmt>,--output-format=<fmt>β sets the reporting format tonormal,tabular,json, orbinary. only one output format at a time, okurrr? don't be greedy. π--output-format-version=<version>β picks the output format version. Version1uses the original field naming, while version2(the default) gives you more consistent and script-friendly field names. any other version gets rejected, no cap. π«--quietβ suppresses informational messages. errors are still reported, and--quietalso cancels any--verbosefor the library log level. she's quiet but she's still watching. π€«--set-options=<key=value>[,<key=value>...]β sets libnvme library options for this one invocation. supported keys areforce-4k,mi-probe-enabled,test-base-dirandtest-sysfs-dir. mix and match, comma-separate, go off. π--timeout=<ms>β sets the timeout for the command in milliseconds.infiniteor-1waits with no time limit at all (0xffffffff). patience is a virtue fr fr β³-v,--verboseβ increases how much detail you get. you can stack it multiple times to get even more verbose. lore drop after lore drop. π
π‘ btw these options can also be set as machine-wide defaults in nvme-cli.conf(5). a command-line flag always overrides the file, so the CLI stays main character. π
π EXAMPLES π
- Displays the get latency monitor log for the device:
# nvme wdc get-latency-monitor-log /dev/nvme0
look at her go. iconic. π§
