Performance Anomaly and Change Point Detection For Large-Scale System Management

Abstract

The presentation starts with the short overview of the classical SPC based anomaly detection techniques and tools including MASF [1]; SETDS, Exception Value (EV) meta-metric based Change Point Detection [2]; Control Chart [3]; business driven massive prediction [4] and methods of using them to manage large-scale systems such as on-prem servers fleet or massive clouds. Then the presentation will be focusing on modern techniques of anomaly and normality detection, such as, deep learning and entropy-based anomalous pattern detections.
