Class FailureHandlingService

java.lang.Object

com.google.common.util.concurrent.AbstractExecutionThreadService

org.graylog.failure.FailureHandlingService

All Implemented Interfaces:

com.google.common.util.concurrent.Service

@Singleton
public class FailureHandlingService
extends com.google.common.util.concurrent.AbstractExecutionThreadService

A service consuming and processing failure batches submitted via FailureSubmissionQueue. The processing is done in a dedicated thread, the lifecycle of this service is managed by ServiceManager. This service is designed with an idea of extensibility, so that Graylog plugins can inject custom failure handlers via Multibinder - see FailureHandler. If no custom handlers found, then the fallback one will be picked instead.
