TROUBLE ANALYSIS APPARATUS
First Claim
1. A trouble analysis apparatus of a computer system constituted from functional elements including hardware and software, comprising:
- a system topology information storing portion storing system topology information which includes both information of the functional elements and information of links between the functional elements that indicates spreading directions of error operations between the functional elements upon trouble;
an error detection information receiving portion collecting error detection information regarding error functional elements that are the functional elements in which error operations are indicated; and
a trouble source determination portion which, based on the error detection information and the system topology information, determines a trouble source functional element from the functional elements that is presumed as a source of the trouble.

Abstract
A trouble analysis apparatus is provided which includes: a system topology storing portion; an error detection information receiving portion which collects error detection information; and a trouble source determination portion which, based on both the error detection information collected by the error detection information receiving portion and system topology information stored in the system topology information storing portion, determines a trouble source functional element that is presumed as a functional element which is a source of a system trouble. Links included in the system topology information have information indicating spreading directions of error operations between the functional elements when trouble occurs. When the trouble source detection portion receives the error detection information with regard to multiple error functional elements, the trouble source determination portion sequentially selects one of the multiple error functional elements. The trouble source detection portion determines whether or not directions from the selected error functional element to other error functional elements conform to the spreading directions included in the system topology information. The trouble source determination portion determines the selected error functional element as the trouble source functional element when the spreading directions are conformable.
