.SH "NAME"
nvme-micron-smart-add-log \- Retrieves NAND statistics (2200 model drives) or Extended SMART information (OCP complaint models) of given micron device
.SH "SYNOPSIS"
.sp
.nf
\fInvme micron vs\-smart\-add\-log\fR <device> \-f <json|normal>
.fi
.SH "DESCRIPTION"
.sp
This command prints NAND information (Total bytes written, Bad block count and Erase failures etc) for the given micron device if its of 2200 model controller\&. For OCP complaint controllers this command print extended SMART health data along with NAND information (if available)
.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
The \fI\-f\fR option controls the displayed output data format based on the option value\&. If the option value is \fIjson\fR (which is enabled by default), output data is printed in JSON format\&. If option value is \fInormal\fR the output is displayed in non\-JSON format\&.
.sp
This will only work on Micron devices devices of model numbers 54XX and OCP complaint controllers\&. Support for new devices may be added subsequently\&.
