Abstract:
1. A non-transitory computer-readable medium embodying a program executable in a computing device, the program comprising: code that detects a plurality of anomalies in a plurality of time series, individual ones of the time series being derived from metrics observed from a computing system, at least two of the time series differing in time resolution, the individual ones of the time series being at least one of non-stationary or heteroskedastic, the plurality of anomalies being detected by: code that partitions the plurality of anomalies according to a time of occurrence; code that identifies co-occurring instances of anomalies in the partitioned anomalies; code that correlates at least a portion of the plurality of anomalies with at least one of a plurality of external events affecting the computing system; code that assigns a magnitude to the co-occurring instances of anomalies; and code that reports the co-occurring instances of anomalies, the assigned magnitude, and the correlated at least one external event.
