nvme-telemetry-log(1) ===================== NAME ---- nvme-telemetry-log - Retrieves a Telemetry Host-Initiated log page from an NVMe device SYNOPSIS -------- [verse] 'nvme telemetry-log' [--output-file= | -O ] [--host-generate= | -g ] [--output-format= | -o ] [--verbose | -v] DESCRIPTION ----------- Retrieves an Telemetry Host-Initiated log page from an NVMe device and provides the returned structure. The 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 :: --output-file=:: File name to which raw binary data will be saved to. -g :: --host-generate=:: 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 :: --data-area=:: 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 :: --output-format=:: 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.
