.SH "NAME"
nvme-self-test-log \- Retrieve the log information initiated by device\-self\-test and display it
.SH "SYNOPSIS"
.sp
.nf
\fInvme self\-test\fR\-log <device> [\-\-log\-entries=<entries> | \-e <entries>]
                        [\-\-output\-format=<fmt> | \-o <fmt>] [\-\-verbose | \-v]
.fi
.SH "DESCRIPTION"
.sp
Retrieves the log pages from an NVMe device corresponding to the requested self\-test by the user and provides 20\-most recent result 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 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 or the json format\&.
.sp
By default the log is printed out in the normal readable format\&.
.SH "OPTION"
.PP
\-e <entries>, \-\-log\-entries=<entries>
.RS 4
Specifies how many DST log entries the program should request from the device\&. This must be at least one, and shouldn\(cqt exceed the 20 entries\&. Defaults to 20 DST log entries\&.
.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\&.
