Explore advanced tracing techniques beyond traditional ring-buffer methods in this 38-minute conference talk by Jérémie Galarneau from EfficiOS. Discover two new mechanisms introduced in LTTng: triggers and aggregation maps. Learn how triggers enable rule-based notifications and tracing configuration changes, allowing for continuous monitoring of systems without excessive data collection. Understand the power of aggregation maps in both kernel and user space for efficient statistics extraction. See how these features can be combined with traditional tracing to gain detailed insights into production systems while minimizing data management challenges.
