Level	Name	Description
0	off	A log level of 0/off tells a Logger or Appender to suspend all logging
100	fatal	Critical error that leads to program abort. Should always indicate a stop() or similar
200	error	A severe error that does not trigger program abort
300	warn	A potentially harmful situation, like warning()
400	info	An informational message on the progress of the application
500	debug	Finer grained informational messages that are mostly useful for debugging
600	trace	An even finer grained message than debug
NA	all	A log level of NA/all tells a Logger or Appender to process all log events
