Hi, current elasticsearch cannot use syslog appender in log4j, because of this:

Correct class must be:
org.apache.log4j.net.SyslogAppender
(not 'log4j.' directly but 'log4j.net.')

Maybe other net. appenders have same problems

How do you configure it?

Something like this in logging.yml:

  syslog:
    type: syslog
    sysloghost: 10.11.11.71
    facility: local0
    layout:
      type: pattern
      conversionPattern: "[%d{ISO8601}][%-5p][%-25c] %m%n"

Right, I see where the problem is, will push a fix. For now, you can just specify the full classname in the type, it should work.
