=====================
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
