nvme-intel-lat-stats — Send NVMe Identify Controller, return result and structure


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.


· Get the read statistics
