Abstract
Methods and systems are directed to detecting and classifying changes in a distributed computing system. Divergence value are computed from distributions of different types of event messages generated in time intervals of a sliding time window. Each divergence value is a measure of change in types of events generated in each time interval. When a divergence value, or a rate of change in divergence values, exceeds a threshold, the time interval associated with the threshold violation is used to determine a change point in the operation of the distributed computing system. Based on the change point, a start time of the change is determined. The change is classified based on various previously classified change points in the disturbed computing system. A recommendation may be generated to address the change based on the classification of the change.
