nvme-smart-log — Send NVMe SMART log page request, returns result and log


nvme smart-log <device> [--namespace-id=<nsid> | -n <nsid>]
                        [--raw-binary | -b]
                        [--output-format=<fmt> | -o <fmt>]


Retrieves the NVMe SMART log page from an NVMe device and provides the retuned 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 smart 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.


-n <nsid>, --namespace-id=<nsid>

Retrieve the SMART log for the given nsid. This is optional and its success may depend on the device’s capabilities to provide this log on a per-namespace basis (see the NVMe Identify Controller for this capability). The default nsid to use is 0xffffffff for the device global SMART log.

-b, --raw-binary

Print the raw SMART log buffer to stdout.
