Abstract

Diagnosis and debugging of performance problems on complex distributed systems requires end-to-end performance information at both the application and system level. We describe a methodology, called NetLogger that enables real-time diagnosis of performance problems in such systems. The methodology includes tools for generating precision event logs, an interface to a system event-monitoring framework, and tools for visualizing the log data and real-time state of the distributed system. Low overhead is an important requirement for such tools; therefore, we evaluate efficiency of the monitoring itself. The approach is novel in that it combines network, host, and application-level monitoring, providing a complete view of the entire system.
