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

[0050] The present invention will be further described in detail below with reference to the drawings and embodiments. It can 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 ease of description, the drawings only show a part but not all of the structure related to the present invention.

[0051] 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 are described as sequential processing in the flowchart, many of the steps can be implemented in parallel, concurrently, or simultaneously. In addition, the order of the steps can be rearranged, and the process can be terminated when its operation is completed, but there can also be other steps not included in the drawings. Processing can correspond to met...

Abstract

The present invention relates to a method and device for analyzing the root cause of IT failures by using temporal correlation, wherein the method includes: obtaining system logs; extracting key fields of the system logs, and performing statistics on the key fields to obtain Obtain the time series data of the system log; automatically extract the relevant features of the time series data based on quantitative hypothesis detection; when an IT failure occurs, test the relevant features of the time series data through Granger causality, wherein, The magnitude of the causal relationship between the relevant features of the time series data is used as the basis for evaluating the cause of the IT failure. The beneficial effects of the present invention are: automatically complete the fault root cause analysis process through machine learning, help users quickly find out the cause of the fault, reduce the fault diagnosis time (Mean Time To Diagonise, MTTD), and make the system return to normal as soon as possible.

Description

Technical field [0001] The embodiments of the present invention relate to the field of information processing technology, and in particular, to a method and device for performing root cause analysis of IT failures using time series correlation. Background technique [0002] Log data is the basis for many enterprise applications such as troubleshooting, monitoring, security, compliance, and electronic forensics. At the same time, they have great analytical value. With the advent of the era of big data, the speed of data generation is accelerating and the volume of data is huge. Human resources alone cannot keep up with the speed of data generation by machines. Most of the content in the log data cannot be directly identified by humans. With the growth of log capacity and types, log data has exceeded human cognition. It is becoming more and more difficult to analyze log content and track potential problems, especially after the emergence of multi-log correlation analysis, which re...
