+NAME
+----
+nvme-smart-log - Send NVMe SMART log page request, returns result and log
+
+SYNOPSIS
+--------
+[verse]
+'nvme smart-log' <device> [--namespace-id=<nsid> | -n <nsid>]
+ [--raw-binary | -b]
+ [--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+Retrieves the NVMe SMART log page from an NVMe device and provides the 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).
+
+On success, the returned smart 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 may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+ Retrieve the SMART log for the given nsid. This is optional
+ and its success may depend on the device's capabilities to
+ provide this log on a per-namespace basis (see the NVMe Identify
+ Controller for this capability). The default nsid to use is
+ 0xffffffff for the device global SMART log.
+
+-b::
+--raw-binary::
+ Print the raw SMART log buffer to stdout.
+
+-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
+--------
+* Print the SMART log page in a human readable format:
++
+------------
+# nvme smart-log /dev/nvme0
+------------
++
+
+* Print the raw SMART log to a file:
++
+------------
+# nvme smart-log /dev/nvme0 --raw-binary > smart_log.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.
