An kafka appender adopted to use with Pega PRPC system.

Based on original log4j-kafka appender.

• Isolate kafka client classloader
• Changed default kafka batch.size
• Added default JSONLayout

1. Put latest log4j2-kafka-appender.jar from releases page into your classpath.
2. Add new appender into log4j2.xml:

   <Configuration status="warn">
       <Appenders>
       <!--...-->
       <ObizKafka name="Kafka" topic="logstash-input-topic">
           <Property name="bootstrap.servers">kafka-host:9092</Property>
       </ObizKafka>
       <!--...-->
       </Appenders>
   <!--...-->
   </Configuration>

3. Add them into root:

   <Configuration status="warn">
   <!--...-->
       <Loggers>
   		<asyncRoot>
   			<AppenderRef ref="CONSOLE"/>
   			<AppenderRef ref="Kafka"/>
   		</asyncRoot>
   	</Loggers>
   <!--...-->
   </Configuration>	

Example of Logstash input

input {
  kafka {
    bootstrap_servers => "kafka-host:9092"
    topics => ["logstash-input-topic"]
    codec => json
  }	
}
