NAME
       nvme-predictable-lat-log - Send Predectible latency per NVM set log page request, returns result and log


SYNOPSIS
       nvme predictable-lat-log <device> [--nvmset-id=<nvmset_id> | -i <nvmset_id>]
                               [--raw-binary | -b]
                               [--output-format=<fmt> | -o <fmt>]


DESCRIPTION
       Retrieves the NVMe Predectible latency per NVM set log page from an NVMe device and provides the returned
       structure.

       The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a
       namespace block device (ex: /dev/nvme0n1).

       On success, the returned Predectible latency per NVM set log structure may be returned in one ofseveral
       ways depending on the option flags; the structure may parsed by the program and printed in a readable
       format or the raw buffer may be printed to stdout for another program to parse.


OPTIONS
       -i <nvmset_id>, --nvmset-id=<nvmset_id>
           Retrieve the Predectible latency per NVM set log for the given nvmset id. This argument is mandatory
           and its success may depend on the device’s statistics to provide this log For More details see NVM
           Express 1.4 Spec. Section 5.14.1.10. The default nvmset id to use is 1 for the device.

       -b, --raw-binary
           Print the raw Predectible latency per NVM set log buffer to stdout.

       -o <format>, --output-format=<format>
           Set the reporting format to normal, json, or binary. Only one output format can be used at a time.


EXAMPLES
       •   Print the Predectible latency per NVM set log page in a human readable format:

               # nvme predictable-lat-log /dev/nvme0

       •   Print the raw Predectible latency per NVM set log to a file:

               # nvme predictable-lat-log /dev/nvme0 --raw-binary > nvmset_log.raw

           It is probably a bad idea to not redirect stdout when using this mode.
