.SH "DESCRIPTION"
.sp
For the NVMe device given, sends the Intel vendor unique device log request and saves the result to a file\&.
.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)\&. If using the character device, the namespace id parameter is mandatory\&.
.sp
This will only work on Intel devices supporting this feature which includes (but not limited to) all the Intel DC P3xxx family of controllers\&. Results for any other device are undefined\&.
.SH "OPTIONS"
.PP
\-l <NUM>, \-\-log=<NUM>
.RS 4
Log type: 0, 1, or 2 for nlog, event log, and assert log, respectively\&.
.RE
.PP
\-n <NUM>, \-\-namespace\-id=<NUM>
.RS 4
Namespace to use\&.
.RE
.PP
\-o <FILE>, \-\-output\-file=<FILE>
.RS 4
Output file; defaults to device name provided
.RE
.PP
\-r <NUM>, \-\-region=<NUM>
.RS 4
Select which core region to retrieve the log from\&. \-1 for all available, if supported by the device\&.
.RE
.PP
\-m <NUM>, \-\-nlognum=<NUM>
.RS 4
When used with
\fInlog\fR, this specifies which nlog to read\&. \-1 for all, if supported by the device\&.
