+Supported parameters depend on the liblog4cplus version used to compile Kea.  This can
+be checked by executing ``kea-dhcp4 -W | grep -i log4cplus`` which will produce output
+like this: ``LOG4CPLUS_VERSION:  2.0.5``.  Consult the documentation in the 
+`log4cplus wiki <https://github.com/log4cplus/log4cplus/wiki>`__ for further information
+about the version you have installed.
