NAME

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

SYNOPSIS

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

DESCRIPTION

       Retrieves the NVMe SMART 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 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.

OPTIONS

       -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.

       -o <format>, --output-format=<format>
           Set the reporting format to normal, json, or binary. Only one output format can be
           used at a time.

EXAMPLES

       •   Print the SMART log page in a human readable format:

               # nvme smart-log /dev/nvme0

       •   Print the raw SMART log to a file:

               # nvme smart-log /dev/nvme0 --raw-binary > smart_log.raw

           It is probably a bad idea to not redirect stdout when using this mode.
