Overrideable Parameters:

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.
MinFreeThreadsCount	int	$Config/MinFreeThreadsCount$	Contagem de Threads Livres Mínima	A fonte de dados determina um limite e uma contagem de threads para cada processo do Mecanismo de Banco de Dados; um alerta será gerado se o limite menos a contagem de threads atual for menor ou igual à contagem de threads livres
NumSamples	int	$Config/NumSamples$	Número de amostras	O número de amostras para calcular a média antes de compará-lo com o limite
SyncTime	string	$Config/SyncTime$	Hora da Sincronização	O tempo de sincronização especificado usando um formato de 24 horas. Pode ser omitido.
CacheExpirationTime	int	$Config/CacheExpirationTime$	Tempo de Expiração do Cache	Especifica a idade máxima de informações de cache que o fluxo de trabalho pode usar. Pode ser omitido.
