Closed-Loop Network Performance Monitoring and Diagnosis with SpiderMon

Watch a 16-minute conference talk from USENIX NSDI '22 exploring SpiderMon, a novel system for closed-loop network performance monitoring and diagnosis. Learn how SpiderMon leverages "wait-for" relations to achieve low overhead and high coverage simultaneously, addressing limitations of existing query-driven and blanket monitoring approaches. Discover the system's key components, including the Always-on Monitor, Diagnosis Trigger, Timeout Filter, and Purple Traffic Meter. Understand how SpiderMon aligns telemetry data and utilizes Wait-For Graphs to accurately and quickly diagnose performance problems in data center networks. Gain insights into the system's evaluation, complexity, and potential impact on network management practices.
