title: Is there a list of Kafka log4j appenders?
body: <p>Is there a list of the log files/appenders that I can configure to enable for kafka/zookeeper?  I can see in the log4j.properties file there are some different appenders defined:</p>
  
  <pre><code>log4j.appender.kafkaAppender
  log4j.appender.statechangeAppender
  log4j.appender.requestAppender
  etc.
  </code></pre>
  
  <p>Is there a listing someplace of the logs/appenders that can be created and managed for Kafka/Zookeeper?</p>
