NVME-LOG-PHY-RX-(1) NVMe Manual NVME-LOG-PHY-RX-(1)

# [NAME](#NAME)

nvme-log-phy-rx-eom - Retrieves a Physical Interface Receiver Eye Opening Measurement log page from an NVMe device

# [SYNOPSIS](#SYNOPSIS)

```
nvme [<global-options>] log phy-rx-eom <device> [--lsp=<field> | -s <field>]


                        [--controller=<id> | -c <id>]
```

# [DESCRIPTION](#DESCRIPTION)

Retrieves a Physical Interface Receiver Eye Opening Measurement 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 it returns 0, error code otherwise.

# [OPTIONS](#OPTIONS)

-s &lt;field&gt;, --lsp=&lt;field&gt;

The log specified field configuring the controller’s action to take during processing of the command and the measurement quality.

-c &lt;id&gt;, --controller=&lt;id&gt;

Controller ID of the controller associated with the PCIe port to be measured.

# [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)

•Start a best quality measurement and retrieve the log page header

```
# nvme log phy-rx-eom /dev/nvme0 --lsp=10
```

•Retrieve a finished best quality measurement on controller with ID 3

```
# nvme log phy-rx-eom /dev/nvme0 --lsp=2 --controller=3
```
