AccessibilityInternal
Support Monitor RecalculateFalse

Member Modules:

ID Module Type TypeId RunAs 
DS DataSource Microsoft.SQLServer.2014.DataSource.DBFileGroupFx.StaleCFPRatio Default
CDErrorState ConditionDetection System.ExpressionFilter Default

Overrideable Parameters:

IDParameterTypeSelectorDisplay NameDescription
IntervalSecondsint$Config/IntervalSeconds$间隔(秒)运行工作流的重复间隔时间(秒)。
SyncTimestring$Config/SyncTime$同步时间使用 24 小时格式指定的同步时间。可以忽略。
Thresholdint$Config/Threshold$阈值收集的比率将与此参数进行比较。
TimeoutSecondsint$Config/TimeoutSeconds$超时(秒)指定允许工作流在被关闭并标记为失败之前运行的时间。
ScriptDelayMsecint$Config/ScriptDelayMsec$脚本延迟(毫秒)此参数将设置工作流执行的连续 T-SQL 查询之间的延迟时间。此参数有助于在有大量目标对象时减少工作流生成的足迹。在更改此参数之前，请咨询 Microsoft 技术支持人员。
NumSamplesint$Config/NumSamples$样本数指示在状态发生更改之前测量值应违反阈值的次数。
