nvme intel lat-stats <device> [--write | -w] [--raw-binary | -b]
For the NVMe device given, retrieves intel vendor specific latency statistics and provides the result and 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 structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout.
- -b, --raw-binary
Print the raw buffer to stdout. Structure is not parsed by program. This overrides the vendor specific and human readable options.
- -w, --write
Get write statistics. Read statistics are returned by default.
