OPERATION MANAGEMENT DEVICE, OPERATION MANAGEMENT METHOD, AND RECORDING MEDIUM IN WHICH OPERATION MANAGEMENT PROGRAM IS RECORDED
Document Type and Number:
WIPO Patent Application WO/2016/103650
Kind Code:
A1
Abstract:
The present invention makes it possible to determine whether there is actually a fault that has occurred in a situation where a specific fault state pertaining to a system to be monitored is continuously detected. An operation management device detects, using the measured value of a performance index pertaining to the system to be monitored and a correlation model representing the relationship between two mutually different performance indices, fault information indicating a fault pertaining to the combination of the two mutually different performance indices. The operation management device holds the detected fault information in chronological order, and determines, on the basis of the fault information, whether the fault information has been detected continuously with respect to a specific combination. The operation management device calculates an abnormality score representing the degree of abnormality pertaining to the performance index on the basis of information that pertains to the combination for which it is determined that the fault information is detected continuously, and information that pertains to other combinations including the specific performance index, among the combinations including the specific performance index and for which the fault information has been detected.
