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.
