NVME-LOG-SMART(1) NVMe Manual NVME-LOG-SMART(1)

# [NAME](#NAME)

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

# [SYNOPSIS](#SYNOPSIS)

```
nvme [<global-options>] log smart <device>


                        [--namespace-id=<nsid> | -n <nsid>]


                        [--raw-binary | -b]
```

# [DESCRIPTION](#DESCRIPTION)

Retrieves the NVMe SMART log page from an NVMe device and provides the returned structure.

The &lt;device&gt; 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](#OPTIONS)

-n &lt;nsid&gt;, --namespace-id=&lt;nsid&gt;

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.

# [GLOBAL OPTIONS](#GLOBAL_OPTIONS)

The following options are defined at the top-level nvme command and are available to this subcommand:

--dry-run

Print the command that would be executed, but do not actually execute it.

--no-ioctl-probing

Disable probing for 64-bit IOCTL support.

--no-retries

Disable retry logic on transient errors.

-o &lt;fmt&gt;, --output-format=&lt;fmt&gt;

Set the reporting format to *normal*, *tabular, 'json*, or *binary*. Only one output format may be used at a time.

--output-format-version=&lt;version&gt;

Select the output format version. Version *1* uses the original field naming, while version *2* (default) provides more consistent and script-friendly field names.

--timeout=&lt;ms&gt;

Set the timeout for the command in milliseconds.

-v, --verbose

Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in [nvme-cli.conf(5)](/man/os/nvme-cli/nvme-cli.conf.5). A command-line flag always overrides the file.

# [EXAMPLES](#EXAMPLES)

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

```
# nvme log smart /dev/nvme0
```

•Print the raw SMART log to a file:

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

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