The `in_unix` Input plugin enables Fluentd to retrieve records from the Unix Domain Socket. The wire protocol is the same as [in\_forward](https://docs.fluentd.org/0.12/input/forward), but the transport layer is different.

## Example Configuration

`in_unix` is included in Fluentd's core. No additional installation process is required.

```
<source>
  @type unix
  path /path/to/socket.sock
</source>
```

Please see the [Config File](https://docs.fluentd.org/0.12/configuration/config-file) article for the basic structure and syntax of the configuration file.

## Parameters

### type (required)

The value must be `unix`.

### path (required)

The path to your Unix Domain Socket.

### backlog

The backlog of Unix Domain Socket. The default is `1024`.

#### log\_level option

The `log_level` option allows the user to set different levels of logging for each plugin. The supported log levels are: `fatal`, `error`, `warn`, `info`, `debug`, and `trace`.

Please see the [logging article](https://docs.fluentd.org/0.12/deployment/logging) for further details.
