This report enables analysis of the occurrence of interruptions according to their symptoms, modes of interruption or causes, identifying both the number of times in which the interruptions of one or more nodes was due to a particular failure mode and applying the Pareto principle for their resolution. At the equipment level, this corresponds to evaluation of individual interruptions. For logical-functional configurations, the impact is measured by propagating the interruptions of its downstream nodes. The interruption types used in each analysis are configurable. This report is appropriate for identifying failure modes, symptoms and critical causes by applying the Pareto principle.
