eBPF Observability Engineering: Building High-Performance Telemetry - Softcover

Inhaltsangabe

Picture this: It’s 3:00 AM. Your production dashboard is flashing red, HTTP request latencies are spiking beyond tolerance, and your traditional user-space APM tools are reporting that everything is... completely normal.

The application logs are clean, yet the system is stalling. You are flying blind because standard tools only see what happens in user space. They miss the hidden lock contentions, block I/O delays, and context-switching overheads happening deep beneath the surface.

I wrote this book because I have been in that hot seat, staring at silent metrics while latency burned through SLAs. I realized that to solve modern performance crises, we have to look deeper. When user-space observability goes dark, the Linux kernel holds the truth. This book is the map I wish I had—a field manual designed to take you straight into Ring 0 so you can diagnose the undiagnosable and build telemetry that never blinks.

Inside this comprehensive manual, you will discover:

• Kernel Data Mechanics: Master BPF Ring Buffers, PERCPU hash maps, and lockless aggregation for lightning-fast data transfer.
• Distributed Tracing & Profiling: Correlate slow application spans directly with kernel-level block I/O latency using OpenTelemetry and W3C trace contexts.
• Prometheus Metric Translation: Convert raw power-of-two kernel latency arrays into cumulative Prometheus histograms seamlessly.
• Verifier Diagnostics & Security: Decode cryptic verifier errors, enforce CAP_BPF least-privilege models, and audit untrusted payloads.
• Multi-Tenant Isolation: Prevent noisy-neighbor CPU thrashing and manage map memory using Linux Memory Control Groups (memcg).
• Essential Cheat Sheets: Quick-reference guides for BPF helper functions, kernel compatibility timelines, and map selection matrices.

This book is engineered specifically for:

• Site Reliability Engineers (SREs) & DevOps Leaders looking to eliminate sidecar performance overhead and gain deep system visibility.
• Systems Programmers & Kernel Engineers eager to master modern libbpf, BTF, and CO-RE distribution patterns.
• Cloud-Native & Security Architects designing zero-trust, identity-aware observability pipelines for Kubernetes.

Prerequisite: A foundational understanding of C or Go and basic Linux CLI operations is all you need—we will build the kernel mastery together.

Stop guessing what happens beneath your stack. It is time to stop treating the Linux kernel like a black box and start leveraging it as your ultimate observability superpower.

Take control of your infrastructure, build high-performance telemetry, and master eBPF today!
