The Lumberjack component has no options.

The Lumberjack component supports 7 endpoint options which are listed below:

Name	Group	Default	Java Type	Description
`host`	consumer		`String`	Required Network interface on which to listen for Lumberjack
`port`	consumer	`5044`	`int`	Network port on which to listen for Lumberjack
`bridgeErrorHandler`	consumer	`false`	`boolean`	Allows for bridging the consumer to the Camel routing Error Handler which mean any exceptions occurred while the consumer is trying to pickup incoming messages or the likes will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the `org.apache.camel.spi.ExceptionHandler` to deal with exceptions that will be logged at WARN/ERROR level and ignored.
`sslContextParameters`	consumer		`SSLContextParameters`	SSL configuration
`exceptionHandler`	consumer (advanced)		`ExceptionHandler`	To let the consumer use a custom `ExceptionHandler`. Notice if the option `bridgeErrorHandler` is enabled then this options is not in use. By default the consumer will deal with exceptions that will be logged at WARN/ERROR level and ignored.
`exchangePattern`	advanced	`InOnly`	`ExchangePattern`	Sets the default exchange pattern when creating an exchange
`synchronous`	advanced	`false`	`boolean`	Sets whether synchronous processing should be strictly used or Camel is allowed to use asynchronous processing (if supported).

Result

The result body is a Map<String, Object> object.

RouteBuilder builder = new RouteBuilder() {
    public void configure() {
       from("lumberjack:0.0.0.0").                  // Listen on all network interfaces using the default port
           setBody(simple("${body[message]}")).     // Select only the log message
