Title:
OPERATION MANAGEMENT DEVICE, OPERATION MANAGEMENT METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/111560
Kind Code:
A1
Abstract:
The present invention accurately determines the causes of failures by invariant analysis. A correlation model memory unit (112) of an operation management device (100) stores a correlation model (122) including one or more correlation functions showing the correlation function between two different metrics among a plurality of metrics in a system. A correlation breakdown detection unit (103) applies a plurality of newly input metric values to the correlation model (122) to detect correlation breakdown of the correlation function included in the correlation model (122). A degree-of-abnormality calculation unit (104) calculates and outputs a centrality that is the degree to which a first metric is estimated to be the center of the distribution of correlation breakdown on the basis of the degree of correlation breakdown of one or more correlation functions between one or more second metrics having a correlation function with the first metric among the plurality of metrics, and one or more metrics other than the first metric.
