ID	ParameterType	Selector	Display Name	Description
IntervalSeconds	int	$Config/IntervalSeconds$	Intervalo (segundos)	O intervalo de tempo recorrente em segundos no qual executa-se o fluxo de trabalho.
TimeoutSeconds	int	$Config/TimeoutSeconds$	Tempo Limite (segundos)	Especifica o tempo que o fluxo de trabalho pode funcionar antes de ser fechado e marcado como com falha.
Threshold	int	$Config/Threshold$	Limite	Se a taxa entre a Recompilação do SQL e a Compilação do SQL for maior do que esse limite, um alerta será gerado
NumSamples	int	$Config/NumSamples$	Número de amostras	Indica quantas vezes um valor medido deve violar um limite antes do estado ser alterado.
SyncTime	string	$Config/SyncTime$	Hora da Sincronização	O tempo de sincronização especificado usando um formato de 24 horas. Pode ser omitido.
