"bpftrace Scripting and Observability" "bpftrace Scripting and Observability" is a comprehensive technical guide to mastering the art and science of dynamic observability on modern Linux systems. Beginning with a thorough exploration of eBPF architecture and the bpftrace scripting paradigm, the book lays a strong foundation for readers to understand how low-overhead, safe, and dynamic kernel and user-space tracing is achieved. It delves into the essential mechanisms of eBPF, including its security model, verifier, and interaction with critical kernel subsystems, demystifying how bpftrace transforms high-level scripts into powerful, production-grade tracing tools. The book methodically teaches the bpftrace language, leaving no stone unturned-from language syntax and scripting idioms to advanced concepts such as associative arrays, custom aggregations, state machines, and stack walking. Readers are guided step-by-step through real-world instrumentation of the network stack, file systems, schedulers, and user-space applications. Special attention is devoted to efficient tracing in high-scale environments, performance engineering, and the subtle art of minimizing observer impact, all grounded in practical scenarios ranging from bare metal to containerized cloud-native infrastructures. Moving beyond core scripting, this volume addresses security, safe operational practices, and integration into CI/CD, DevOps, and production observability pipelines. Case studies and automation workflows illustrate how bpftrace fits into large-scale enterprise and cloud-native settings, ensuring secure, auditable, and scalable observability. Finally, readers are invited to extend bpftrace itself-exploring its extensibility, interoperability with the wider eBPF ecosystem, and ongoing innovations in the open-source community. Suitable for both observability practitioners and systems engineers, this book delivers the expert guidance necessary to unlock the full potential of bpftrace in modern systems monitoring and performance troubleshooting.
