Problems solved by technology

The root cause analysis of business failures has always relied on the experience and trial and error of operation and maintenance personnel. Only the simplest hardware failures can achieve a little alarm convergence through simple parent (origin, parent element) settings. There is no method or device that can better solve the above problems

Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0052] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the steps in the flowcharts are described as sequential processing, many of the steps may be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the steps may be rearranged, the process may be terminated when its operations are complete, but may also have other steps not included in the figures....

Abstract

The invention relates to a method and a device for utilizing time sequence correlation to perform IT fault root cause analysis. The method comprises the steps that system logs are acquired; key fields of the system logs are extracted, and statistical analysis is performed on the key fields to obtain time sequence data of the system logs; relevant features of the time sequence data are automatically extracted based on quantitative hypothetic detection; and when an IT fault occurs, the relevant features of the time sequence data are inspected through Granger causality, wherein a quantitative value of the causality between all the relevant features of the time sequence data serves as a basis for evaluating an occurrence cause of the IT fault. The method and the device have the advantages that a fault root cause analysis process is completed automatically by means of machine learning, a user is helped to quickly find out the fault occurrence cause, fault diagnosis time (Mean Time To Diagnose, MTTD) is shortened, and a system is returned to normal in a highest speed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information processing, and in particular to a method and device for analyzing root causes of IT failures by using time series correlation. Background technique [0002] Log data is the foundation of many enterprise applications such as troubleshooting, monitoring, security, compliance, e-discovery, and many others. At the same time, they have great analytical value. With the advent of the big data era, the speed of data generation is accelerating and the volume of data is huge. Manpower alone cannot keep up with the speed of data generation by machines. Most of the content in log data cannot be directly identified by humans. With the growth of log volume and types, log data exceeds human cognitive ability, and it becomes more and more difficult to analyze log content and track down potential problems, especially after the emergence of multi-log correlation analysis, experienced...
