Abstract
(EN)
[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.

L'objectif de l'invention est de spécifier avec précision une zone d'influence d'une défaillance logicielle. Pour ce faire, l'invention concerne une unité de traitement qui détermine qu'un trajet de communication entre deux appareils ayant une relation corrélative concernant un état d'utilisation de ressources est un trajet de transmission d'informations. L'unité de traitement (12) génère ensuite un modèle de propagation d'influence (13) qui indique le sens de propagation d'influence d'une défaillance logicielle dans le trajet de transmission d'informations d'après la probabilité de cooccurrence de message entre un premier appareil et un second appareil. Un ordinateur acquiert ensuite des informations de défaillance (14) qui indiquent un appareil dans lequel une défaillance logicielle s'est produite. L'ordinateur spécifie ensuite qu'un appareil atteignable en traçant le trajet de transmission d'informations à partir de l'appareil défaillant dans le sens de propagation indiqué par le modèle de propagation d'influence du logiciel est un appareil influencé dans lequel se propage l'influence de la défaillance survenue dans l'appareil défaillant, puis génère des informations indiquant l'appareil influencé.

【課題】ソフトウェアの障害の影響範囲を正確に特定できるようにする。 【解決手段】処理部12は、リソースの使用状況の相関関係を有する2つの機器間の通信経路を、情報伝達経路と判定する。次に処理部12は、第1機器と第2機器との間のメッセージの共起確率に基づいて、情報伝達経路内でのソフトウェアの障害の影響の伝搬方向を示す影響伝搬モデル13を生成する。その後、コンピュータは、一ソフトウェアの障害が発生した障害発生機器を示す障害情報14を取得する。そしてコンピュータは、情報伝達経路上を、障害発生機器から、該一ソフトウェアの影響伝搬モデルに示される伝搬方向に辿ることで到達できる機器を、障害発生機器で発生した障害の影響が伝搬する影響機器として特定して、影響機器を示す情報を出力する。
