=== Unix input plugin

include::{include_path}/plugin_header.asciidoc[]

==== Description

Read events over a UNIX socket.

Like `stdin` and `file` inputs, each event is assumed to be one line of text.

Can either accept connections from clients or connect to a server,
depending on `mode`.

&nbsp;

[id="plugins-{type}s-{plugin}-data_timeout"]
===== `data_timeout` 

  * Value type is <<number,number>>
  * Default value is `-1`

The 'read' timeout in seconds. If a particular connection is idle for
more than this timeout period, we will assume it is dead and close it.

If you never want to timeout, use -1.

[id="plugins-{type}s-{plugin}-force_unlink"]
===== `force_unlink` 

  * Value type is <<boolean,boolean>>
  * Default value is `false`

Remove socket file in case of EADDRINUSE failure

[id="plugins-{type}s-{plugin}-mode"]
===== `mode` 

  * Value can be any of: `server`, `client`
  * Default value is `"server"`

Mode to operate in. `server` listens for client connections,
`client` connects to a server.

[id="plugins-{type}s-{plugin}-path"]
===== `path` 

  * This is a required setting.
  * Value type is <<string,string>>
  * There is no default value for this setting.

When mode is `server`, the path to listen on.
When mode is `client`, the path to connect to.

[id="plugins-{type}s-{plugin}-socket_not_present_retry_interval_seconds"]
===== `socket_not_present_retry_interval_seconds` 

  * This is a required setting.
  * Value type is <<number,number>>
  * Default value is `5`

Amount of time in seconds to wait if the socket file is not present, before retrying.
Only positive values are allowed.

This setting is only used if `mode` is `client`.
