Abstract: Relationships between alarms are modeled using a graph to identify root cause of a sequence of alarms (an alarm flood). The nodes of the graph represent different alarms, and the edges between the nodes are scored using pairwise analysis of when the alarms occurred. The graph is divided into multiple subgraphs representing alarm clusters. Root cause analysis of the sequence of alarms is performed by generating and simplifying directed graphs for events within the alarm clusters.
