	Score	Host	ScoreHostTrace	Logs details about how Workload Balancing is arriving at a score
	Trace			for a host.
				This trace shows the detailed scores generated by Workload
				Balancing when it calculates the star ratings for selecting
				optimal servers for VM placement.

	Audit	Log	AuditLogTrace	Shows the action of the audit log data being captured and
	Trace			written.
				(This is generally only for internal use and does not provide
				information that is captured in the audit log.)
				However, leaving this trace on will increase the log file size
				quickly.

	Scheduled		ScheduledTaskTrace	Logs details about scheduled tasks.
	Task Trace			For example, if your scheduled mode changes or report
				For example, if your scheduled mode changes or report
				subscriptions are not working, you might want to enable this
				trace to investigate the cause.

	Web		WlbWebServiceTrace	Logs details about the communication with the web-service
	Service			interface.
