NVME-TELEMETRY-LOG(1) NVMe Manual NVME-TELEMETRY-LOG(1) 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 NVME Part of the nvme-user suite NVMe 10/31/2024 NVME-TELEMETRY-LOG(1)
