This post details how Netflix leverages eBPF flow logs to enhance its real-time service topology system, specifically focusing on the network layer. It describes the challenges of collecting and processing high-volume network flow data at scale, the architecture of the eBPF-based data collection pipeline, and how this data is integrated into the existing topology system to provide granular network insights. The post highlights the use of eBPF for efficient kernel-level data capture and the subsequent processing and aggregation of this data to build a comprehensive view of service interdependencies.
