Abstract

A method of identifying a hidden anomaly in a stream of time-series data. The stream of time-series data is parsed into a number of sub-streams. Each sub-stream in the number of sub-streams includes a parameter in a number of parameters. A number of policies are executed on the number of sub-streams. Executing outputs a first set of values in a current time window for each of the number of sub-streams. For the each sub-stream, a corresponding difference determination is generated by comparing, for the each sub-stream, the first set of values in the current time window to a second set of values in a past time window for the each sub-stream. When, for a sub-stream, a difference determination satisfies a threshold, an alert is returned that the hidden anomaly occurred with respect to the parameter for the selected sub-stream.
