Description

edit

Receive events using the Lumberjack protocol.

This input can be used to reliably and securely transport events between Logstash instances. To do so, use the lumberjack output plugin in the sending Logstash instance(s).

It can also be used to receive events from the deprecated logstash-forwarder tool that has been replaced by Filebeat.

Consider using the Beats input plugin instead. The Beats input implements the Lumberjack protocol v1 and v2.

Lumberjack Input Configuration Options

edit

This plugin supports the following configuration options plus the Common Options described later.

Setting	Input type	Required
`congestion_threshold`	number	No
`host`	string	No
`port`	number	Yes
`ssl_certificate`	a valid filesystem path	Yes
`ssl_key`	a valid filesystem path	Yes
`ssl_key_passphrase`	password	No

Also see Common Options for a list of options supported by all input plugins.

`congestion_threshold`

edit

Value type is number
Default value is 5

The number of seconds before we raise a timeout, this option is useful to control how much time to wait if something is blocking the pipeline.

`host`

edit

Value type is string
Default value is "0.0.0.0"

The IP address to listen on.

`port`

edit

This is a required setting.
Value type is number
There is no default value for this setting.

The port to listen on.

`ssl_certificate`

edit

This is a required setting.
Value type is path
There is no default value for this setting.

SSL certificate to use.

`ssl_key`

edit

This is a required setting.
Value type is path
There is no default value for this setting.

SSL key to use.

`ssl_key_passphrase`

edit

Value type is password
There is no default value for this setting.

SSL key passphrase to use.

Common Options

edit

The following configuration options are supported by all input plugins:

Setting	Input type	Required
`add_field`	hash	No
`codec`	codec	No
`enable_metric`	boolean	No
`id`	string	No
`tags`	array	No
`type`	string	No

Details

edit

`add_field`

edit

Value type is hash
Default value is {}

Add a field to an event

`codec`

edit

Value type is codec
Default value is "plain"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.

`enable_metric`

edit

Value type is boolean
Default value is true

Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.

`id`

edit

Value type is string
There is no default value for this setting.

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type, for example, if you have 2 lumberjack inputs. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

input {
  lumberjack {
    id => "my_plugin_id"
  }
}

Variable substitution in the id field only supports environment variables and does not support the use of values from the secret store.

`tags`

edit

Value type is array
There is no default value for this setting.

Add any number of arbitrary tags to your event.

This can help with processing later.

`type`

edit

Value type is string
There is no default value for this setting.

Add a type field to all events handled by this input.

Types are used mainly for filter activation.

The type is stored as part of the event itself, so you can also use the type to search for it in Kibana.

If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.
