Have you looked at http://logging.apache.org/log4j/2.x/manual/webapp.html? The
documentation there is missing one thing that will probably help you. You can
specify
<context-param>
<param-name>log4jConfiguration</param-name>
<param-value>file://etc/myApp/mylogging-${sys:region}.xml</param-value>
</context-param>
If you then set the region system property to "prod" you would use
mylogging-prod.xml.
