Embodiment 1

[0088] Embodiment 1: as Figure 1-4 As shown, a cloud computing fault data detection method includes:

[0089] The cloud computing fault training data processing step is to process the data in the cloud computing fault training data set to obtain the degree of membership of each fault training data and the fault feature weight of each fault category;

[0090] The step of judging the fault category of the cloud computing data to be detected is to judge the category of the cloud computing data to be detected according to the processing results of the fault training data and in combination with the expansion rules of the cloud computing fault training data set;

[0091] In the step of expanding the cloud computing fault training data set, the cloud computing data to be detected and its category information satisfying the expansion rules of the cloud computing fault training data set are added to the fault training data expansion set.

[0102]

[0103] In this example, cloud computing fault data is used as the fault training data set D. The D is composed of 2 fault categories and 10 fault training data, and each data has 4 fault features, in which category 1 is cloud computing network fault, category 2 is cloud computing IO port fault, and the 4 fault features are cpu usage rate, hard disk usage, IO port usage and network usage; D={D 1 ,...D i ,...,D m},D i ={x i1 ,...,x ij ,...,x in}, xij=[x ij1 ,...,x ijl ,...,x ijp ,c i ], i=1,.2,...,m, j=1,2,...,n, l=1,2,...,p, where D i is the fault training data of fault category i, x ij is the training data for the jth fault in the fault category i, x ijl is the lth fault feature of the jth fault training data in fault ...

Abstract

The invention relates to a cloud computing fault data detection method and system, and belongs to the field of cloud fault detection. The cloud computing fault data detection method comprises: a cloudcomputing fault training data processing step: processing the data in a cloud computing fault training data set to obtain a degree of membership of each cloud computing fault training data and the fault feature weight of each fault category; a to-be-detected cloud computing data fault category judgment step: judging the fault category of the to-be-detected cloud computing data according to the processing result of the cloud computing fault training data in combination with a cloud computing fault training data set expansion rule; and a cloud computing fault training data set expansion step: adding the to-be-detected cloud computing data satisfying the cloud computing fault training data set expansion rule and the category thereof to a fault training data set. By adoption of the cloud computing fault data detection method and system, the fault training data model is perfected beneficially, and new faults are identified.

Description

technical field [0001] The invention relates to a cloud computing fault data detection method and system, belonging to the field of cloud fault detection. Background technique [0002] Fault detection mainly studies how to detect, separate and identify faults in the system, that is, to judge whether a fault occurs, locate the location and type of the fault, and determine the size and time of the fault. In recent years, the application technology of cloud computing has become more and more extensive. However, a large number of malicious attacks and its own complexity and large-scale make the system and various software and hardware on it often fail, causing some or even all services to fail. Cloud computing fault detection technology has become a research hotspot in this field. Rao Xiang et al. proposed a fault feature extraction method based on fault injection testing, first filtering the noise log; then constructing a fault recognizer to identify the early features of diff...
