NAME¶
nvme-telemetry-log - Retrieves a Telemetry Host-Initiated log page from an NVMe device
SYNOPSIS¶
nvme telemetry-log <device> [--output-file=<file> | -o <file>]
[--host-generate=<gen> | -g <gen>]
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. If this option is not specified, the default value is 3, since that
will always give the user all three data areas.
EXAMPLES¶
•Retrieve Telemetry Host-Initiated data to
telemetry_log.bin
# nvme telemetry-log /dev/nvme0 --output-file=telemetry_log.bin
