Wildfly logging pattern elements - Is there a documentation?

Question

I am using Wildfly 10.1 and I would really like to know what logging pattern elements i could use.

I found this documentation here: https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html referenced by a Wildfly book.

But this can not be the whole truth, because there are more elements than mentioned there, for example the %s or %E Elements.

I also found this https://logging.apache.org/log4j/2.x/manual/layouts.html but that cant be the truth eiter, because the mentioned %throwable{short.className} does not work.

Also the Wildfly Documentation at https://docs.jboss.org/author/display/WFLY10/Handlers#Handlers-formatter does not say a word about what pattern elements are available.

I try to create a logging pattern which will generate only one line per exception (no stack trace) but still contain the Message of the exception and the Class, Method and Line Number.

Now there is a document for logging formatters. Wildfly Logging Formatters

You could use %l for location information, but there is no pattern for exception message without stacktrace.

Here is the relevant parts from the document;

%l: The location information. This includes the callers class name, method name, file name and line number.

%m: The formatted message including any stack traces.

%s: The simple formatted message. This will not include the stack trace if a cause was logged.

%e: Prints the full stack trace.

%e{0}: Prints the stack trace ignoring any suppressed messages.

%e{1}: Prints the stack trace with a maximum of one suppressed message.
