Synchronous delay detection method and device

The invention relates to the technical field of synchronous delay detection, in particular to a synchronous delay detection method and device. According to the synchronous delay detection method based on the sliding window, the influence of IO delay and the like is fully considered, and by comparing three continuous time window increments of a target node with a time window increment corresponding to a source node, it is ensured that the synchronous delay can be detected after a certain degree of delay occurs; and the service operation and maintenance team can conveniently locate problems in time, and the availability of platform services is better guaranteed. 本发明涉及同步延迟检测技术领域，尤其是指一种同步延迟检测方法及装置。本发明所述的基于滑动窗口的同步延迟检测方法，充分考虑了IO延迟等影响，通过设置目标节点三个连续时间窗口增量与源节点对应一个时间窗口增量的对比，确保如同步延迟出现一定程度的延迟后可以检测出来，方便业务运维团队及时定位问题，更好地保障平台业务的可用性。
