The debug and debug-verbose Parameters
If debug is set to true, then log messages with WARN and INFO severity levels are written to the servlet log. If it is set to false, only FATAL and ERROR level messages are logged.
If debug-verbose is set to true, then TRACE and DEBUG level log messages are written.
* 
Setting debug-verbose to true includes messages from daemon threads that run every few seconds, so use this parameter with caution and only during troubleshooting.
