Complex systems are prevalent in many fields such as finance, security and industry. A fundamental problem in system management is to perform diagnosis in case of system failure such that the causal anomalies, i.e., root causes, can be identified for system debugging and repair. Recently, invariant network has proven a powerful tool in characterizing complex system behaviors. In an invariant network,...
An accurate and automated identification of operational behavior switching is critical to the autonomic management of complex systems. In this paper, we collect sensor readings from those systems, which are treated as time series, and propose a solution to discover switching behaviors by inferring the relationship changes among massive time series. The method first learns a sequence of local relationship...
