Embodiment 1

[0064] This embodiment takes OpenStack integration as an example to illustrate the method of the present invention.

[0065] 1) if figure 1 As shown, to build a knowledge base, the specific implementation steps are as follows:

[0066] 1.1) Generate a data source.

[0067] In the offline cloud computing environment, use the command line interface provided by the cloud operating system to write scripts to simulate large-scale concurrent operation requests from different users, analyze data based on the historical exceptions of the cloud environment, and combine fault injection technology and scene reproduction methods to restore the cloud The processing process of service exceptions, and finally collect the logs of each node and component of OpenStack on each server node as a data source for building training data.

[0068] Further, during the submission process of each type of operation request:

[0069] 1.1.1) Submit a small number of requests sequentially in a fixed time ...

Abstract

The invention relates to a log-based cloud service problem fine-grained intelligent tracing method. The method is characterized by comprising the following steps: 1) based on historical abnormal record data of a cloud operating system, combining a fault injection technology, and abstracting an overall related system task execution mode reflected by cross-component logs under various abnormal scenes by utilizing time correlation analysis and a machine learning algorithm, thereby constructing a knowledge base; and 2) identifying an overall related system task execution mode corresponding to thelog newly generated by the cloud operation system by using the knowledge base, thereby achieving the purpose of fine-grained cloud service exception automatic tracing. According to the invention, historical analysis data in a cloud environment are fully utilized by means of an intelligent machine learning method; the knowledge base is obtained through training and used for identifying a new log mode and capturing the overall effect of multi-component collaborative services in a cloud environment, so that the purpose of automatic cloud service exception tracing is achieved, and the method can be widely applied to intelligent tracing of cloud service exception problems in the field of cloud computing.

Description

technical field [0001] The invention belongs to the field of cloud computing, and in particular relates to a log-based fine-grained intelligent traceability method for cloud service problems. Aiming at the cloud operating system environment, the mixed log big data generated by many cloud service nodes is comprehensively utilized, and intelligent technology of machine learning is used. Learn and accumulate knowledge from the exceptions encountered, and automatically find the root cause of the service exceptions corresponding to cloud user operations. Background technique [0002] Cloud computing provides a mode of on-demand self-service access to computing resources through the network. These resources come from a shared highly elastic virtual resource pool. availability. With the help of open source cloud operating systems such as OpenStack, organizations such as schools, enterprises, and governments can build personalized private clouds, public clouds, and hybrid clouds. ...
