syslogAppender pattern

[jinhong lu]

Hi, 

  I want to write log to rsyslog

when I use log4j1.x，I use this to define the pattern:

                appender.setLayout(new PatternLayout("%r " + loggerName +" [%t] 
%-5p %C%x - %m %C"));

How can I do the same thing in log4j2.x?

Now I get the message like this:
Nov 24 17:26:59 liaoliuqingdeMacBook-Air.local MyApp  ljh_test message 

I even can not see the level of the log. So how can I set the pattern in 
log4j2.x syslogPattern.

here is my configuration
