AREA OF INFLUENCE SPECIFYING PROGRAM, AREA OF INFLUENCE SPECIFYING METHOD, AND AREA OF INFLUENCE SPECIFYING DEVICE

摘要

[Problem] To accurately specify an area of influence of software fault. [Solution] A processing unit 12 determines that a communication path between two apparatuses having a correlative relationship pertaining to a resource use state is an information transmission path. Next, the processing unit 12 generates an influence propagation model 13 that indicates the direction of propagation of influence of software fault in the information transmission path on the basis of the probability of message cooccurrence between a first apparatus and a second apparatus. Thereafter, a computer acquires fault information 14 that indicates a fault-occurred apparatus in which software fault has occurred. Then the computer specifies an apparatus reachable by tracing the information transmission path from the fault-occurred apparatus in the direction of propagation indicated by the software influence propagation model as an influenced apparatus to which the influence of the fault occurred in the fault-occurred apparatus propagates, and outputs information that indicates the influenced apparatus.
