NAME
       nvme-pred-lat-event-agg-log - Send Predictable Latency Event Aggregate
       Log Page	request, returns result	and log

SYNOPSIS
       nvme pred-lat-event-agg-log <device>
			       [--log-entries=<log_entries> | -e <log_entries>]
			       [--rae |	-r] [--raw-binary | -b]
			       [--output-format=<fmt> |	-o <fmt>] [--verbose | -v]

DESCRIPTION
       Retrieves the NVMe Predictable Latency Event Aggregate 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 Event Aggregate Log	Page
       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
       -e <log_entries>, --log-entries=<log_entries>
	   Retrieve the	Predictable Latency Event Aggregate Log	pending
	   entries. 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 5.14.1.11. The	maximum	number of log
	   entries supported is	2044 for the device.

       -r, --rae
	   Retain an Asynchronous Event.

       -b, --raw-binary
	   Print the raw Predictable Latency Event Aggregate 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.

EXAMPLES
       •   Print the Predictable Latency Event Aggregate Log page in a human
	   readable format:

	       # nvme pred-lat-event-agg-log /dev/nvme0

       •   Print the raw Predictable Latency Event Aggregate log to a file:

	       # nvme pred-lat-event-agg-log /dev/nvme0	--raw-binary > pred_lat_agg_log.raw

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