IDParameterTypeSelectorDisplay NameDescription
IntervalSecondsint$Config/IntervalSeconds$間隔 (秒)每次重複執行工作流程之間的時間間隔 (秒)。
SyncTimestring$Config/SyncTime$同步處理時間同步處理時間使用 24 小時制。可予省略。
Thresholdint$Config/Threshold$閾值如果「奪取伺服器記憶體/SQL Server 記憶體上限」的比率大於此臨界值，則會產生警示。
NumSamplesint$Config/NumSamples$範例數指出測出的值要違反多少次臨界值，狀態才會變更。
TimeoutSecondsint$Config/TimeoutSeconds$逾時 (秒)指定流程被關閉及標示為失敗之前，允許執行的時間。
SqlTimeoutSecondsint$Config/SqlTimeoutSeconds$資料庫連線的逾時 (秒)若工作流程無法在指定的期限之內存取資料庫，將會失敗並登錄一則事件。
