NAME
       nvme-predictable-lat-log	- Send Predictable 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>] [--verbose | -v]

DESCRIPTION
       Retrieves the NVMe Predictable 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	Predictable latency per	NVM set	log structure
       may be returned in one of several 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	Predictable 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 Predictable latency per NVM set log buffer to stdout.

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

       -v, --verbose
	   Increase the	information detail in the output.

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

	       # nvme predictable-lat-log /dev/nvme0

       •   Print the raw Predictable 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.
