Due to their growing complexity, it becomes extremely difficult to detect and isolate faults in complex systems. While large amount of monitoring data can be collected from such systems for fault analysis, one challenge is how to correlate the data effectively across distributed systems and observation time. Much of the internal monitoring data reacts to the volume of user requests accordingly when user requests flow through distributed systems. In this paper, we use Gaussian mixture models to… CONTINUE READING
