Overrideable Parameters:

IDParameterTypeSelectorDisplay NameDescription
IntervalSecondsint$Config/IntervalSeconds$Interval (seconds)The recurring interval of time in seconds in which to run the workflow.
SyncTimestring$Config/SyncTime$Synchronization TimeThe synchronization time specified by using a 24-hour format. May be omitted.
MinFreeThreadsCountint$Config/MinFreeThreadsCount$Minimum Free Threads ThresholdThe workflow determines the maximum number of threads and the number of active threads for each DB Engine process. An alert will be generated if the number of free threads is less or equal than this parameter.
NumSamplesint$Config/NumSamples$Number of samplesIndicates how many times a measured value should breach a threshold before the state is changed.
TimeoutSecondsint$Config/TimeoutSeconds$Timeout (seconds)Specifies the time the workflow is allowed to run before being closed and marked as failed.
SqlExecTimeoutSecondsint$Config/SqlExecTimeoutSeconds$Timeout for query execution (seconds)The workflow will fail and register an event, if the query execution takes longer than the specified period.
SqlTimeoutSecondsint$Config/SqlTimeoutSeconds$Timeout for database connection (seconds)The workflow will fail and register an event, if it cannot access the database during the specified period.
