NAME

6       nvme-smart-log - Send NVMe SMART log page request, returns result and
7       log
8

SYNOPSIS

10       nvme smart-log <device> [--namespace-id=<nsid> | -n <nsid>]
11                               [--raw-binary | -b]
12                               [--output-format=<fmt> | -o <fmt>]
13

DESCRIPTION

15       Retrieves the NVMe SMART log page from an NVMe device and provides the
16       returned structure.
17
18       The <device> parameter is mandatory and may be either the NVMe
19       character device (ex: /dev/nvme0), or a namespace block device (ex:
20       /dev/nvme0n1).
21
22       On success, the returned smart log structure may be returned in one of
23       several ways depending on the option flags; the structure may parsed by
24       the program and printed in a readable format or the raw buffer may be
25       printed to stdout for another program to parse.
26

OPTIONS

28       -n <nsid>, --namespace-id=<nsid>
29           Retrieve the SMART log for the given nsid. This is optional and its
30           success may depend on the device’s capabilities to provide this log
31           on a per-namespace basis (see the NVMe Identify Controller for this
32           capability). The default nsid to use is 0xffffffff for the device
33           global SMART log.
34
35       -b, --raw-binary
36           Print the raw SMART log buffer to stdout.
37
38       -o <format>, --output-format=<format>
39           Set the reporting format to normal, json, or binary. Only one
40           output format can be used at a time.
41

EXAMPLES

43       ·   Print the SMART log page in a human readable format:
44
45               # nvme smart-log /dev/nvme0
46
47       ·   Print the raw SMART log to a file:
48
49               # nvme smart-log /dev/nvme0 --raw-binary > smart_log.raw
50
51           It is probably a bad idea to not redirect stdout when using this
52           mode.
