Operation management apparatus, operation management method, and recording medium on which operation management program is recorded

摘要

It is possible to determine whether or not a failure has actually occurred in a situation where a specific failure state related to the monitored system is continuously detected. The operation management apparatus uses the measured value of the performance index related to the monitoring target system and the correlation model representing the relationship between the two different performance indexes to indicate failure information indicating a failure related to the combination of the two different performance indexes. To detect. The operation management apparatus holds the detected failure information in time series, and determines whether the failure information is continuously detected for the specific combination based on the failure information. The operation management apparatus includes information regarding the combination in which it is determined that the failure information is continuously detected among the combinations in which the failure information is detected including the specific performance index, and includes the specific performance index. Based on the information related to the other combinations, an abnormality score representing the degree of abnormality related to the performance index is calculated.
