This plugin supports the following configuration options:

Required configuration options:

udp {
    port => ...
}

Available configuration options:

Setting	Input type	Required
`add_field`	hash	No
`buffer_size`	number	No
`codec`	codec	No
`enable_metric`	boolean	No
`host`	string	No
`id`	string	No
`port`	number	Yes
`queue_size`	number	No
`receive_buffer_bytes`	number	No
`tags`	array	No
`type`	string	No
`workers`	number	No

Details

edit

`add_field`

edit

Value type is hash
Default value is {}

Add a field to an event

`buffer_size`

edit

Value type is number
Default value is 65536

The maximum packet size to read from the network

`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.

`host`

edit

Value type is string
Default value is "0.0.0.0"

The address which logstash will listen on.

`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 grok filters. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

output {
 stdout {
   id => "my_plugin_id"
 }
}

`port`

edit

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

The port which logstash will listen on. Remember that ports less than 1024 (privileged ports) may require root or elevated privileges to use.

`queue_size`

edit

Value type is number
Default value is 2000

This is the number of unprocessed UDP packets you can hold in memory before packets will start dropping.

`receive_buffer_bytes`

edit

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

The socket receive buffer size in bytes. If option is not set, the operating system default is used. The operating system will use the max allowed value if receive_buffer_bytes is larger than allowed. Consult your operating system documentation if you need to increase this max allowed value.

`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.

This is the base class for Logstash inputs. 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.

`workers`

edit

Value type is number
Default value is 2

Number of threads processing packets
