# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.fluentd.org/0.12/input/unix.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
