example

[0066] S1: Suppose there are 5 abnormal requests A, B, C, D, E, whether the abnormality has been calibrated, so there is no abnormality detection step, and this step is not the content of the present invention, but should be regarded as the precondition or Trigger; Table 1 is the request details of the embodiment,

[0067]

[0068] Table 1

[0069] S2: Perform the following calculation for each abnormal request. First, traverse the call chain from the request header, and perform 3δ abnormal filtering on the service instances accessed by each request; then, score the abnormal service instances one by one for the results of abnormal filtering; Finally, input the score, dependencies of all service instances, and service instance information covered by each request into the custom PageRank matrix for iteration, and obtain the abnormal score of the service instance;

[0070] S21: Depth-first traverse each abnormal request from beginning to end, and use the 3δ method to filter a...

Abstract

The invention discloses a root cause positioning algorithm based on call chain data. Anomaly detection is performed on the call chain data of a time window, if an anomaly occurs, the call chain data is traversed from the request header of each abnormal request, exceptions are filtered from each service instance requested to be accessed through 3delta exception filtering, and are scored one by one,and the scores, the dependency relationship among the service instances and the information of each service instance requested to be covered by each request are input into a custom square matrix andare subjected to iterative computation to obtain a service instance exception score; the requested coverage condition of the service instance of the normal request, the requested coverage condition ofthe service instance and the dependency relationship between the service instances are input into a custom square matrix and are subjected to iterative computation to obtain a normal score of the service instance; and a final score of each service instance is calculated by adopting a spectrum method in combination with the abnormal score and the normal score of the service instance, and a suspicious service instance list is returned according to the final score. A fault root cause list with a ranking sequence is output, so that the troubleshooting range of operation and maintenance personnelis reduced.

Description

technical field [0001] The invention relates to the field of intelligent operation and maintenance, in particular to a root cause location algorithm based on call chain data. Background technique [0002] The current software architecture is rapidly changing from a monolith to a microservices architecture. With the microservice architecture, applications can decouple complex interactions into many loosely coupled fine-grained services based on business functions. However, due to the complex dependencies between services in the microservice environment, the application of continuous integration and delivery tools, and the dynamic runtime environment, when one or several services in the environment have errors or failures, it will cause a series of service levels. Connection fails. Therefore, when a fault occurs, it is very important to locate the root cause of the fault in time. Contents of the invention [0003] In order to overcome at least one defect (deficiency) desc...
