What I Learned From Building an eBPF-Based Traffic Capture Application
Building a targeted eBPF network traffic capture tool reveals why a general-purpose eBPF observability agent is exponentially harder. Learn about the brutal challenges of language ABI hell, performance overhead, and context correlation (Goroutines, etc.) that major vendors must solve. eBPF is a scalpel, not a sledgehammer. Discover where it truly shines and where its complexity explodes.
