Chapter 216. Lumberjack Component Available as of Camel version 2.18 The Lumberjack component retrieves logs sent over the network using the Lumberjack protocol, from Filebeat for instance. The network communication can be secured with SSL. This component only supports consumer endpoints. Maven users will need to add the following dependency to their pom.xml for this component: <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-lumberjack</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency> 216.1. URI format lumberjack:host lumberjack:host:port You can append query options to the URI in the following format, ?option=value&option=value&... 216.2. Options The Lumberjack component supports 3 options, which are listed below. Name Description Default Type sslContextParameters (security) Sets the default SSL configuration to use for all the endpoints. You can also configure it directly at the endpoint level. SSLContextParameters useGlobalSslContext Parameters (security) Enable usage of global SSL context parameters. false boolean resolveProperty Placeholders (advanced) Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true boolean The Lumberjack endpoint is configured using URI syntax: with the following path and query parameters: 216.2.1. Path Parameters (2 parameters): Name Description Default Type host Required Network interface on which to listen for Lumberjack String port Network port on which to listen for Lumberjack 5044 int 216.2.2. Query Parameters (5 parameters): Name Description Default Type bridgeErrorHandler (consumer) 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 or ERROR level and ignored. false boolean sslContextParameters (consumer) SSL configuration SSLContextParameters exceptionHandler (consumer) To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. ExceptionHandler exchangePattern (consumer) Sets the exchange pattern when the consumer creates an exchange. ExchangePattern synchronous (advanced) Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). false boolean 216.3. Spring Boot Auto-Configuration The component supports 4 options, which are listed below. Name Description Default Type camel.component.lumberjack.enabled Enable lumberjack component true Boolean camel.component.lumberjack.resolve-property-placeholders Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true Boolean camel.component.lumberjack.ssl-context-parameters Sets the default SSL configuration to use for all the endpoints. You can also configure it directly at the endpoint level. The option is a org.apache.camel.util.jsse.SSLContextParameters type. String camel.component.lumberjack.use-global-ssl-context-parameters Enable usage of global SSL context parameters. false Boolean 216.4. Result The result body is a Map<String, Object> object. 216.5. Lumberjack Usage Samples 216.5.1. Example 1: Streaming the log messages RouteBuilder builder = new RouteBuilder() { public void configure() { from("lumberjack:0.0.0.0"). // Listen on all network interfaces using the default port setBody(simple("USD{body[message]}")). // Select only the log message to("stream:out"); // Write it into the output stream } };
