nvme-telemetry-log − Retrieves a Telemetry Host−Initiated log page from an NVMe device
nvme
telemetry−log <device>
[−−output−file=<file> | −o
<file>]
[−−host−generate=<gen> | −g
<gen>]
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.
−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.
