| 发明名称 | Apparatus, method and storage medium for fault cause extraction utilizing performance values | ||
| 摘要 | A fault cause extraction apparatus including a storage unit which stores a model including one or more correlation functions between pieces of performance information acquired from a plurality of elements and a correlation-destruction-propagation detecting unit which calculates a degree of influence for each of the elements based on correlation destruction information. The correlation destruction information is calculated based on whether pieces of performance information newly acquired from the elements satisfy a relationship represented by the correlation functions. | ||

| 主权项 | 1. A fault cause extraction apparatus comprising: a storage unit which stores a model including one or more correlation functions between pieces of performance information acquired from a plurality of elements in a system; and a correlation-destruction-propagation detecting unit which calculates a degree of influence upon said system for each of said elements based on correlation destruction information, wherein said correlation destruction information is calculated based on whether pieces of performance information newly acquired from said elements satisfy a relationship represented by said correlation functions. | ||
