Class StructuredSyslogMessageProcessor

java.lang.Object

org.graylog2.syslog4j.impl.message.processor.AbstractSyslogMessageProcessor

org.graylog2.syslog4j.impl.message.processor.structured.StructuredSyslogMessageProcessor

All Implemented Interfaces:

Serializable, SyslogConstants, SyslogMessageProcessorIF

public class StructuredSyslogMessageProcessor
extends AbstractSyslogMessageProcessor

SyslogStructuredMessageProcessor extends SyslogMessageProcessor's ability to split a syslog message into multiple messages when the message is greater than the syslog maximum message length (1024 bytes including the header). It adds support for structured syslog messages as specified by draft-ietf-syslog-protocol-23. More information here:

http://tools.ietf.org/html/draft-ietf-syslog-protocol-23

Those wishing to replace (or improve upon) this implementation can write a custom SyslogMessageProcessorIF and set it per instance via the SyslogIF.setStructuredMessageProcessor(..) method or set it globally via the StructuredSyslogMessageProcessor.setDefault(..) method.
