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
