Abstract
An event management method of attributing a seasonal fault to maintenance activity is described. The method includes identifying a sequence of fault events as a seasonal fault, and calculating an initial seasonality metric indicating a degree of seasonality of the sequence of fault events. One or more maintenance windows are identified, and then a subset of the sequence of the fault events which correspond in time with the maintenance windows are identified. A compensated seasonality metric is calculated for the sequence of fault events minus at least some of the subset of fault events. Based on determining that the compensated seasonality metric indicates a reduction in seasonality compared with the initial seasonality metric, an indication that the sequence of fault events is associated with maintenance activities is generated.
