Embodiment Construction
[0041] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0042] figure 1 It is a schematic flow chart of the location method for the root cause change in the embodiment of the present invention, such as figure 1 As shown, this embodiment mainly includes:
[0043] Step 101, based on the occurrence time of the fault event, determine the corresponding root cause change candidate set.
[0044] In this step, changes within a certain range will be selected based on the occurrence time of the fault event to construct a root cause change candidate set, so that the root cause change of the fault event can be screened within the range of the set in subsequent steps.
[0045] Specifically, in one embodiment, it is possible to find out from the entire software system all changes that satisfy the requirem...

The present application discloses a root cause change location method and device, wherein the method includes: determining the corresponding root cause change candidate set based on the occurrence time of the fault event; for each change in the root cause change candidate set, determining A preset feature correlation degree between the change and the fault event, based on the feature correlation degree, determine the root cause score of the change, wherein the feature correlation degree is based on the change and the fault event The corresponding feature distances between are obtained; based on the descending order of the root cause scores, the changes in the root cause change candidate set are sorted, and the sorting results are used as the recommended order of root cause changes and output. According to the present application, for the changes in the root cause change candidate set, the root cause scores are generated according to the preset feature correlation degree, and sorted based on the root cause scores, which can effectively improve the location efficiency of the root cause changes.
Description
technical field [0001] The invention relates to computer application technology, in particular to a method and device for locating root cause changes. Background technique [0002] In large-scale software services, engineers usually make frequent software changes to fix existing vulnerabilities (bugs), improve the performance of the software system, modify configurations, and so on. Because software changes will change the configuration or code of the system, it is easy to cause failures. According to the experience in the book "Google SRE", 70% of failures are caused by changes. In a large-scale system, there are a large number of failure events every day. If the failure events are not recovered in time, the system performance will be seriously affected, resulting in economic losses and degrading user experience. Therefore, after a fault event occurs, it is necessary to quickly locate the root cause change corresponding to the fault event, that is, determine which histori...
