NVME-PREDICTABLE-L(1) NVMe Manual NVME-PREDICTABLE-L(1) NAME nvme-predictable-lat-log - Send Predictable latency per NVM set log page request, returns result and log SYNOPSIS nvme predictable-lat-log <device> [--nvmset-id=<nvmset_id> | -i <nvmset_id>] [--raw-binary | -b] [--output-format=<fmt> | -o <fmt>] [--verbose | -v] DESCRIPTION Retrieves the NVMe Predictable latency per NVM set 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 Predictable latency per NVM set log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse. OPTIONS -i <nvmset_id>, --nvmset-id=<nvmset_id> Retrieve the Predictable latency per NVM set log for the given nvmset id. This argument is mandatory and its success may depend on the de- vice's statistics to provide this log For More details see NVM Express 1.4 Spec. Section 5.14.1.10. The default nvmset id to use is 1 for the device. -b, --raw-binary Print the raw Predictable latency per NVM set log buffer to stdout. -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 * Print the Predictable latency per NVM set log page in a human readable format: # nvme predictable-lat-log /dev/nvme0 * Print the raw Predictable latency per NVM set log to a file: # nvme predictable-lat-log /dev/nvme0 --raw-binary > nvmset_log.raw It is probably a bad idea to not redirect stdout when using this mode. NVME Part of the nvme-user suite NVMe 10/31/2024 NVME-PREDICTABLE-L(1)
