Rule Construction and its Execution for Root Cause Analysis

Abstract

We have developed a root cause analysis system for enterprise IT system environment. In this paper, we propose a rule construction method which builds the analysis rule data object from the general analysis rules and the topology information of the actual target IT environment. By this method, IT administrator can use RCA system without any manual rule modifications. Regarding execution of analysis, we introduce the certainty factor to realize a robust analysis when the ordinarily and reachability of fault event can not be guaranteed.
