Explore how Meta leverages DAMON, a Linux kernel subsystem, for efficient data access monitoring and fleet-wide memory management optimization in this 34-minute conference talk. Learn about the initial limitations of DAMON, including the lack of page-level information observability and the requirement for manual parameter tuning per workload. Discover the newly developed DAMON features that have been integrated upstream to address these challenges, including their design principles, practical usage, and evaluation results. Examine Meta's fleet-level monitoring system architecture built on the enhanced DAMON capabilities and gain insights from real-world fleet-wide data access pattern analysis. Understand the remaining technical limitations in DAMON that continue to impact the efficiency and utility of large-scale access monitoring systems, and explore the long-term objectives of Meta's data access pattern observability project.
