| 摘要 |
An objective of the present invention is to carry out fault analysis using an appropriate correlation model in invariant relational analysis even if a system configuration has changed. An operation administration device (100) comprises a correlation model generation unit (102), a configuration change detector unit (107), and a fault analysis unit (104). The correlation model generation unit (102) generates a correlation model (122) which includes one or more correlation functions which denote correlation relations between two different metrics among a plurality of metrics of a system. The configuration change detector unit (107) detects whether a system configuration change has occurred. If a system configuration change is detected by the configuration change detector unit (107), the fault analysis unit (104) identifies a system fault chief cause, using the correlation model (122) which is generated based on the measured values of the plurality of post-system configuration change metrics. |
