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$Config/Threshold$阈值针对此参数比较收集的比率。
CfpCountThresholdint$Config/CfpCountThreshold$检查点文件对阈值如果检查点文件对总数大于或等于检查点文件对阈值，则生成警报。
SqlTimeoutSecondsint$Config/SqlTimeoutSeconds$数据库连接超时(秒)如果在指定期间无法访问数据库，工作流将失败并注册一个事件。
TimeoutSecondsint$Config/TimeoutSeconds$超时(秒)指定工作流在关闭之前允许运行的时间，并标记为失败。
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。
