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>]
[−−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

# nvme telemetry−log /dev/nvme0 −−output−file=telemetry_log.bin
