IDParameterTypeSelectorDisplay NameDescription
IntervalSecondsint$Config/IntervalSeconds$Intervalo (segundos)O intervalo de tempo recorrente em segundos no qual executar o fluxo de trabalho.
SyncTimestring$Config/SyncTime$Tempo de SincronizaçãoO tempo de sincronização especificado usando um formato de 24 horas. Pode ser omitido.
MinFreeThreadsCountint$Config/MinFreeThreadsCount$Limite de Threads Livres MínimosO fluxo de trabalho determina o número máximo de threads e o número de threads ativos para cada processo do Mecanismo do Banco de Dados. Um alerta será gerado se o número de threads livres for menor ou igual a esse parâmetro.
NumSamplesint$Config/NumSamples$Número de amostrasIndica quantas vezes um valor medido deve romper um limite antes que o estado seja alterado.
TimeoutSecondsint$Config/TimeoutSeconds$Tempo Limite (em segundos)Especifica o tempo que o fluxo de trabalho pode para ser executado antes de ser fechado e marcado como falha.
SqlTimeoutSecondsint$Config/SqlTimeoutSeconds$Tempo limite da conexão de banco de dados (segundos)O fluxo de trabalho falhará e registrará um evento, se ele não conseguir acessar o banco de dados durante o período especificado.
