SYNOPSIS
nvme

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.
