+==============================

+NAME
+----
+nvme-pred-lat-event-agg-log - Send Predictable Latency Event Aggregate Log
+Page request, returns result and log
+
+SYNOPSIS
+--------
+[verse]
+'nvme pred-lat-event-agg-log' <device> [--log-entries=<log_entries> | -e <log_entries>]
+			[--rae | -r] [--raw-binary | -b]
+			[--output-format=<fmt> | -o <fmt>]
+
+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 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
+-------
+-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 Predectible Latency Event Aggregate 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 Predictable Latency Event Aggregate Log page in a human readable format:
++
+------------
+# nvme pred-lat-event-agg-log /dev/nvme0
+------------
++
+
+* Print the raw Predectible 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.
