ID	ParameterType	Selector	Display Name	Description
IntervalSeconds	int	$Config/IntervalSeconds$	Interval Seconds	The recurring interval of time in seconds in which to run the workflow.
WaitMinutes	int	$Config/WaitMinutes$	Wait Minutes	Wait Minutes parameter defines the minimum waiting time for the session to be considered by the monitor.
SyncTime	string	$Config/SyncTime$	Synchronization Time	The synchronization time specified by using a 24-hour format. May be omitted.
SampleCount	int	$Config/SampleCount$	Number of samples	Health State changes if the number of threshold breaches is greater than or equal to the Minimum Number of Breaches.
Threshold	double	$Config/Threshold$	Critical Threshold	Health State changes when the number of blocked sessions exceeds the threshold.
TimeoutSeconds	int	$Config/TimeoutSeconds$	Timeout (seconds)	Specifies the time the workflow is allowed to run before being closed and marked as failed.
