nvme-predictable-lat-log - Send Predictable latency per NVM set log page request, returns result and log
nvme predictable-lat-log <device> [--nvmset-id=<nvmset_id> | -i <nvmset_id>]
[--raw-binary | -b]
[--output-format=<fmt> | -o <fmt>]
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.
-i <nvmset_id>, --nvmset-id=<nvmset_id>
-b, --raw-binary
-o <format>, --output-format=<format>
# nvme predictable-lat-log /dev/nvme0
# 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.
