Index relevance determination method and device

Abstract

The invention discloses an index relevance determination method and device. The method comprises the following steps of: obtaining an index value of each sampling point, in a same time period, of a first index and a second index; obtaining first variable quantities, in time intervals corresponding to adjacent sampling points of the first index, of the first index according to the index values of the adjacent sampling points, and obtaining a first variable quantity set, in the time period, of the first index by utilizing the first variable quantities of all the sampling points; determining second variable quantities, in time intervals corresponding to adjacent sampling points of the second index, of the second index according to the index values of the adjacent sampling points, and obtaining a second variable quantity set, in the time period, of the second index by utilizing the second variable quantities of all the sampling points; obtaining a confidence coefficient indicating an association relationship between the first index and the second index according to the first variable quantity set and the second variable quantity set; and if the confidence coefficient is greater than or equal to a preset first threshold value, determining that the association relationship exists between the first index and the second index. The method is high in degree of automation and high in efficiency.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a method and device for determining the relevance of indicators. Background technique [0002] When monitoring the running status of a device, it is usually necessary to establish an association relationship of the monitoring indicators based on the collected monitoring indicator data. At present, the correlation between monitoring indicators is mainly established manually based on experience. However, this method has a low degree of automation, takes a long time, and has poor usability when there are many monitoring devices. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the first purpose of the present invention is to propose a method for determining the correlation of indicators, through the index values ​​of the sampling points of the first...

Problems solved by technology

[0004] For this reason, the first purpose of the present invention is to propose a method for determining the correlation of indicators, through the index values ​​of the sampling points of the first indicator and the second indicator in the same time period, calculate the correlation between the two indicators in all sampling intervals Change amount, and obtain the change amount set, obtain the confidence degree of the two indicators according to the change amount set of the two indicators, and then determine whether there is a relationship between the two indicators according to the confidence degree, and realize the specific data calculation. The correlation between the two indicators can be determined, which solves the problems of time-consuming, low efficiency, and poor usability in the existing technology of manually establishing the correlation relationship of indicators based on experience
