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 1,2,3,4. If this option is not specified, the default value is 3, since
data area 4 may not be supported.
EXAMPLES¶
•Retrieve Telemetry Host-Initiated data to
telemetry_log.bin
# nvme telemetry-log /dev/nvme0 --output-file=telemetry_log.bin
