Proactive fault detection schema for enterprise information system using statistical process control

Abstract

This paper proposes a proactive fault detection schema using adaptive statistical approaches in order to enhance system availability and reliability in the heterogeneous & complicated information system environment. The proposed system applies Six Sigma SPC (Statistical Process Control) techniques already validated in industries in order to monitor the application system in the information system. This makes it possible to reduce false alarm rates for system faults and accurately detect faults by creating a control chart based on past performance data and controlling the distribution of performance based on the chart. The early detection of faults is also enabled through a fault prediction model. Therefore, the aforementioned system not only detect unknown or unseen faults but also resolve potential problems for system administrator by detecting abnormal behaviors before faults occur. In the experiment we show the superiority of our proposed model and the possibility to early detect system faults. © 2009 Springer Berlin Heidelberg.
