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, but the transport layer is different.

It is included in Fluentd's core.

Example Configuration

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

Refer to the Configuration File article for the basic structure and syntax of the configuration file.

Parameters

@type (required)

The value must be unix.

path

type	default	version
string	/var/run/fluent/fluent.sock (see below)	0.14.0

The path to your Unix Domain Socket.

Fluentd will use the environment variable FLUENT_SOCKET if defined.

backlog

type	default	version
integer	1024	0.14.0

The backlog of Unix Domain Socket.

tag

type	default	version
string	nil	1.11.0

in_unix uses incoming event's tag by default. If the tag parameter is set, its value is used instead.
