Abstract The technological development has allowed the reduction of costs involved in purchasing personal and high-end computers. Such resources started composing large scale as well as heterogeneous enviroments. Those enviroments have a high probability to experience faults, due to the number and heterogeneity of hardware and software resources. In order to reduce the resource downtime, several researchers have been conducted aiming at detecting faults and failures in such environments, pointing out such perturbations to system administrators. However, recent researches have been addressing the fault prediction by analysing information obtained through resource monitoring. Those researches are limited to forecast future events based on short-term memories. Such limitations motivated this work which proposes the study and application of dynamical system tools to analyze the long-term behavior of time series as a way to model and predict faults. Such series are unfolded and regressed in order to better observe tendencies, which support fault predictions and, therefore, the failure avoidance. (AU) | |
