.SH "DESCRIPTION"
.sp
For the NVMe device given, send a Vendor Unique WDC vs\-nand\-stats command and output the NAND statistics\&. The \-\-output\-format option will format the output as specified\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0)\&.
.sp
This will only work on WDC devices supporting this feature\&. Results for any other device are undefined\&.
.sp
On success it returns the NAND statistics, error code otherwise\&.
.SH "OPTIONS"
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR, or
\fIjson\fR\&. Only one output format can be used at a time\&. Default is normal\&.
