# unix
The `in_unix` Input plugin enables Fluentd to retrieve records from the Unix Domain Socket. The wire protocol is the same as [in\_forward](/0.12/input/forward.md), but the transport layer is different.
## Example Configuration
`in_unix` is included in Fluentd's core. No additional installation process is required.
```
@type unix
path /path/to/socket.sock
```
Please see the [Config File](/0.12/configuration/config-file.md) 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](/0.12/deployment/logging.md) for further details.
