+.SH "DESCRIPTION"
+.sp
+For the NVMe device given, sends an identify controller command and provides the result and 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
+This will only work on WDC devices supporting this feature\&. Results for any other device are undefined\&.
+.sp
+On success, the structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout\&.
+.sp
+If having the program decode the output for readability, this version will decode WDC vendor unique portions of the structure\&.
+.SH "OPTIONS"
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw buffer to stdout\&. Structure is not parsed by program\&. This overrides the vendor specific and human readable options\&.
+.RE
+.PP
+\-v, \-\-vendor\-specific
+.RS 4
+In addition to parsing known fields, this option will dump the vendor specific region of the structure in hex with ascii interpretation\&.
+.RE
+.PP
+\-H, \-\-human\-readable
+.RS 4
+This option will parse and format many of the bit fields into human\-readable formats\&.

+NAME
+----
+nvme-wdc-id-ctrl - Send NVMe Identify Controller, return result and structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme wdc id-ctrl' <device> [-v | --vendor-specific] [-b | --raw-binary]
+ [-o <fmt> | --output-format=<fmt>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an identify controller command and
+provides the result and returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+This will only work on WDC devices supporting this feature.
+Results for any other device are undefined.
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+If having the program decode the output for readability, this version
+will decode WDC vendor unique portions of the structure.
+
+OPTIONS
+-------
+-b::
+--raw-binary::
+ Print the raw buffer to stdout. Structure is not parsed by
+ program. This overrides the vendor specific and human readable options.
+
+-v::
+--vendor-specific::
+ In addition to parsing known fields, this option will dump
+ the vendor specific region of the structure in hex with ascii
+ interpretation.
+
+-H::
+--human-readable::
+ This option will parse and format many of the bit fields
+ into human-readable formats.
+
+-o <format>::
+--output-format=<format>::
+ Set the reporting format to 'normal', 'json', or
+ 'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:

+nvme-wdc-smart-log-add - Send NVMe WDC smart-log-add Vendor Unique Command, return result
+
+SYNOPSIS
+--------
+[verse]
+'nvme wdc smart-log-add' <device> [--interval=<NUM>, -i <NUM>] [--output-format=<normal|json> -o <normal|json>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, send a Vendor Unique WDC smart-log-add command and
+provide the additional smart log. The --interval option will return performance
+statistics from the specified reporting interval.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0).
+
+This will only work on WDC devices supporting this feature.
+Results for any other device are undefined.
+
+On success it returns 0, error code otherwise.
+
+OPTIONS
+-------
+-i <NUM>::
+--interval=<NUM>::
+ Return the statistics from specific interval, defaults to 14

+|Number of host read commands received during the reporting period.
+
+|*Host Read Blocks*
+|Number of 512-byte blocks requested during the reporting period.
+
+|*Average Read Size*
+|Average Read size is calculated using (Host Read Blocks/Host Read Commands).
+
+|*Host Read Cache Hit Commands*
+|Number of host read commands that serviced entirely from the on-board read
+cache during the reporting period. No access to the NAND flash memory was required.
+This count is only updated if the entire command was serviced from the cache memory.
+
+|*Host Read Cache Hit Percentage*
+|Percentage of host read commands satisfied from the cache.
+
+|*Host Read Cache Hit Blocks*
+|Number of 512-byte blocks of data that have been returned for Host Read Cache Hit
+Commands during the reporting period. This count is only updated with the blocks
+returned for host read commands that were serviced entirely from cache memory.
+
+|*Average Read Cache Hit Size*
+|Average size of read commands satisfied from the cache.
+
+|*Host Read Commands Stalled*
+|Number of host read commands that were stalled due to a lack of resources within
+the SSD during the reporting period (NAND flash command queue full, low cache page count,
+cache page contention, etc.). Commands are not considered stalled if the only reason for
+the delay was waiting for the data to be physically read from the NAND flash. It is normal
+to expect this count to equal zero on heavily utilized systems.
+
+|*Host Read Commands Stalled Percentage*
+|Percentage of read commands that were stalled. If the figure is consistently high,
+then consideration should be given to spreading the data across multiple SSDs.
+
+|*Host Write Commands*
+|Number of host write commands received during the reporting period.
+
+|*Host Write Blocks*
+|Number of 512-byte blocks written during the reporting period.
+
+|*Average Write Size*
+|Average Write size calculated using (Host Write Blocks/Host Write Commands).
+
+|*Host Write Odd Start Commands*
+|Number of host write commands that started on a non-aligned boundary during
+the reporting period. The size of the boundary alignment is normally 4K; therefore
+this returns the number of commands that started on a non-4K aligned boundary.
+The SSD requires slightly more time to process non-aligned write commands than it
+does to process aligned write commands.
+
+|*Host Write Odd Start Commands Percentage*
+|Percentage of host write commands that started on a non-aligned boundary. If this
+figure is equal to or near 100%, and the NAND Read Before Write value is also high,
+then the user should investigate the possibility of offsetting the file system. For
+Microsoft Windows systems, the user can use Diskpart. For Unix-based operating systems,
+there is normally a method whereby file system partitions can be placed where required.
+
+|*Host Write Odd End Commands*
+|Number of host write commands that ended on a non-aligned boundary during the
+reporting period. The size of the boundary alignment is normally 4K; therefore this
+returns the number of commands that ended on a non-4K aligned boundary.
+
+|*Host Write Odd End Commands Percentage*
+|Percentage of host write commands that ended on a non-aligned boundary.
+
+|*Host Write Commands Stalled*
+|Number of host write commands that were stalled due to a lack of resources within the
+SSD during the reporting period. The most likely cause is that the write data was being
+received faster than it could be saved to the NAND flash memory. If there was a large
+volume of read commands being processed simultaneously, then other causes might include
+the NAND flash command queue being full, low cache page count, or cache page contention, etc.
+It is normal to expect this count to be non-zero on heavily utilized systems.
+
+|*Host Write Commands Stalled Percentage*
+|Percentage of write commands that were stalled. If the figure is consistently high, then
+consideration should be given to spreading the data across multiple SSDs.
+
+|*NAND Read Commands*
+|Number of read commands issued to the NAND devices during the reporting period.
+This figure will normally be much higher than the host read commands figure, as the data
+needed to satisfy a single host read command may be spread across several NAND flash devices.
+
+|*NAND Read Blocks*
+|Number of 512-byte blocks requested from NAND flash devices during the reporting period.
+This figure would normally be about the same as the host read blocks figure
+
+|*Average NAND Read Size*
+|Average size of NAND read commands.
+
+|*NAND Write Commands*
+|Number of write commands issued to the NAND devices during the reporting period.
+There is no real correlation between the number of host write commands issued and the
+number of NAND Write Commands.
+
+|*NAND Write Blocks*
+|Number of 512-byte blocks written to the NAND flash devices during the reporting period.
+This figure would normally be about the same as the host write blocks figure.
+
+|*Average NAND Write Size*
+|Average size of NAND write commands. This figure should never be greater than 128K, as
+this is the maximum size write that is ever issued to a NAND device.
+
+|*NAND Read Before Write*
+|This is the number of read before write operations that were required to process
+non-aligned host write commands during the reporting period. See Host Write Odd Start
+Commands and Host Write Odd End Commands. NAND Read Before Write operations have
+a detrimental effect on the overall performance of the device.
