STATISTICAL PATTERN CORRELATION OF EVENTS IN CLOUD DEPLOYMENTS USING CODEBOOK APPROACH

摘要

Correlations between patterns of events generated by various separate components within a cloud deployment are statistically determined. The determinations of the correlations can be based on dependencies between the components as indicated by a system topology graph including the components. The patterns correlated can be patterns of events from event streams generated by monitoring systems that monitor the components. The events in the event streams can represent changes over time in component state, behavior, or problem occurrence. Because the quantity of components within such a cloud deployment can be enormous, the quantity of events generated by the monitoring systems over a significant period of time can be voluminous.

1. A method comprising:
generating, by a computing device, a primary code sequence based on a primary event stream; generating, by the computing device, a secondary code sequence based on a secondary event stream; determining, by the computing device, a plurality of correlation coefficients based on different alignments of the primary code sequence with the secondary code sequence; selecting, by the computing device, one or more particular correlation coefficients from the plurality of correlation coefficients; storing, by the computing device, the one or more particular correlation coefficients in association with the secondary event stream and the primary event stream; and accessing, by the computing device, the one or more particular correlation coefficients to quantify a possible relationship between the secondary event stream and the primary event stream.
