Abstract

Automated analysis of time series describing performance indicators is a common requirement for efficient monitoring of large, complex, distributed IT systems. One of the most challenging tasks in time series analysis is anomaly detection as the anomalies may indicate failures or misuse of an IT system. In this paper we focus on anomaly detection methods in time series describing key performance indicators of an IT system. We study the existing methods and propose two new approaches. Our results have been verified in a series of experiments.(original abstract)
