We are developing a root cause analysis technique and fault management technique for reliable systems. Root
cause analysis is difficult especially in distributed systems. This is because each machine issues its events of a fault which may be propagated by a fault of another machine. We propose a new root cause analysis method in which fault propagation models are calculated with maximum likelihood analysis. In this method, a user specifies a small fault analysis rules without fault propagation specifications because fault propagation specifications are automatically complemented by machine learning of event logs. We implemented a prototype system, and we can find that the proposed system can detect a root cause and its source device in high precision when propagated faults occur in short time since the original fault occurs. |
