Correlation-aware explainable online change point detection

A system for correlation-aware explainable online change point detection, comprising:

• a memory device;
• and
• one or more processor devices operatively coupled with the memory device to:
• transform collected data metrics from a cloud system to correlation matrices;
• capture correlation shifts from the correlation matrices as differences of correlation between batches of collected data metrics through determined statistics of the batches of collected data metrics across timesteps;
• detect change points in the cloud system based on the correlation shifts to obtain detected change points;
• and
• perform system maintenance autonomously based on the detected change points from identified system entities to optimize the cloud system with an updated configuration.

A non-transitory computer program product comprising a computer-readable storage medium including program code for correlation-aware explainable online change point detection, wherein the program code when executed on a computer causes the computer to:

• transform collected data metrics from a cloud system to correlation matrices;
• capture correlation shifts from the correlation matrices as differences of correlation between batches of collected data metrics through determined statistics of the batches of collected data metrics across timesteps;
• detect change points in the cloud system based on the correlation shifts to obtain detected change points;
• and
• perform system maintenance autonomously based on the detected change points from identified system entities to optimize the cloud system with an updated configuration through root cause analysis to generate explanations of the change points obtained from a status of the cloud system to assist a decision making of a cloud system professional.
