Overrideable Parameters:

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.
TimeoutSeconds	int	$Config/TimeoutSeconds$	Timeout (seconds)	Specifies the time the workflow is allowed to run before being closed and marked as failed.
Threshold	int	$Config/Threshold$	Threshold	Alert threshold value
NumSamples	int	$Config/NumSamples$	Number of samples	If the parameter threshold exceeding count is greater or equal to the number of samples, then the monitor will be in a bad state
