The Extended Berkeley Packet Filter (eBPF) is transforming how engineers observe, secure, and optimize Linux systems. Once confined to kernel hackers and low-level developers, eBPF now empowers modern DevOps teams, SREs, and performance engineers to build real-time observability, tracing, and security tools directly inside the Linux kernel-without recompiling or rebooting. It's the next evolution of Linux performance engineering and the cornerstone of cloud-native observability across Kubernetes, containers, and microservices.
Written by a seasoned Linux systems engineer and performance optimization expert, this guide is built for professionals who demand clarity, precision, and production-grade insight. Drawing from real-world cloud infrastructure and observability stacks, it goes far beyond tutorials-offering the in-depth architecture, verified code examples, and kernel-level debugging techniques that today's engineers use in advanced DevOps and SRE environments.
Custom eBPF Programming Guide is a complete, hands-on roadmap for building your own kernel-level monitoring and performance tools using C, Go, and CO-RE (Compile Once, Run Everywhere). It transforms eBPF from a complex concept into a practical skillset. From understanding the eBPF verifier and instruction set to developing real-world observability applications, this book equips you with a deep mastery of how to write, load, and manage eBPF programs for performance tuning, system tracing, network security, and runtime analytics.
You'll learn to integrate eBPF with Grafana, Prometheus, and modern CI/CD pipelines, and how to safely extend kernel capabilities without compromising system stability.
