You find the reference here: http://logging.apache.org/log4j/2.x/manual/layouts.html#PatternLayout

You can do something like this:
{code:xml}
<PatternLayout pattern='{"timeMillis":%d{UNIX_MILLIS},"thread":"%enc{%thread}{JSON}","level":"%enc{%level}{JSON}","loggerName":"%enc{%logger}{JSON}","message":"%enc{%m}{JSON}","thrown":"%enc{%ex}{JSON}"}'
                           alwaysWriteExceptions="false"/>
{code}

> We ran into a problem when setting {{locationInfo}} to {{true}} when ingesting logs into Kibana.  The problem had to do with a conflict with another existing key named {{"source"}} of type String, and the fact that {{locationInfo}} produces an Object called "source".
> So it would be nice to have a way to supply a different Object name.  Perhaps this could be broadened so that other key names could also be renamed?
> Maybe there is a way to do this already?
