.SH "NAME"
nvme-endurance-event-agg-log \- Send NVMe Endurance log page request, returns result and log
.SH "SYNOPSIS"
.sp

\fInvme endurance\-event\-agg\-log\fR <device> [\-\-log\-entries=<log_entries> | \-e <log_entries>]

.SH "DESCRIPTION"
.sp
Retrieves the NVMe Endurance Event Aggregate log page from an NVMe device and provides the returned structure\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
.sp
On success, the returned endurance event agg 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, the raw buffer may be printed to stdout for another program to parse, or reported in json format\&.
.SH "OPTIONS"
.PP
\-e <log_entries>, \-\-log\-entries=<log_entries>
.RS 4
Retrieve the Endurance Group Event Aggregate Log pending entries\&. This argument is mandatory and its success may depend on the device\(cqs statistics to provide this log For More details see NVM Express 1\&.4 Spec\&. Section 5\&.14\&.1\&.15\&. The maximum number of log entries supported is 2044 for the device\&.
.RE
.PP
\-r, \-\-rae
.RS 4
Retain an Asynchronous Event\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fIjson\fR
or
\fIbinary\fR\&. Only one output format can be used at a time\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the information detail in the output\&.

.ie n \{\

Print the raw Endurance log to a file:
.sp
.if n \{\

.nf
# nvme endurance\-event\-agg\-log /dev/nvme0 \-\-output=binary > endurance_event_agg_log\&.raw

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