An information collection approach for network monitoring
Tie Luo · Journal of the Graduate School of the Chinese Academy of Sciences · 2009
Large network systems need monitoring to detect flaws and bottlenecks. Many existing monitoring tools only provide overall statistics about global performance metrics. In order to expose the system's internal behavior,we propose a metadata based approach to record the actual execution paths. We have designed proper data structure and information propagation mechanisms to trace the application's internal critical performance-related events. This approach can apply to many network protocols and applications,and it helps capture the sequential and causal relations across domains. Thus it opens a way to diagnose large and complex network systems.
