+NAME
+----
+nvme-telemetry-log - Retrieves a Telemetry Host-Initiated log page from an NVMe device
+
+SYNOPSIS
+--------
+[verse]
+'nvme telemetry-log' <device> [--output-file=<file> | -O <file>]
+ [--host-generate=<gen> | -g <gen>]
+ [--output-format=<fmt> | -o <fmt>] [--verbose | -v]
+
+DESCRIPTION
+-----------
+Retrieves an Telemetry Host-Initiated 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 log structure will be in raw binary format _only_ with
+--output-file option which is mandatory.
+
+OPTIONS
+-------
+-O <file>::
+--output-file=<file>::
+ File name to which raw binary data will be saved to.
+
+-g <gen>::
+--host-generate=<gen>::
+ If set to 1, controller shall capture the Telemetry Host-Initiated data
+ representing the internal state of the controller at the time the
+ associated Get Log Page command is processed.
+ If cleated to 0, controller shall _not_ update this data.
+
+-d <da>::
+--data-area=<da>::
+ Retrieves the specific data area requested. Valid inputs are 1,2,3,4. If
+ this option is not specified, the default value is 3, since data area
+ 4 may not be supported.
+
+-o <fmt>::
+--output-format=<fmt>::
+ Set the reporting format to 'normal', 'json' or 'binary'. Only one
+ output format can be used at a time.
+
+-v::
+--verbose::
+ Increase the information detail in the output.
+
+EXAMPLES
+--------
+* Retrieve Telemetry Host-Initiated data to telemetry_log.bin
