BPF и соответствующие инструменты наблюдения обеспечивают профессионалам программного обеспечения беспрецедентный обзор программного обеспечения, помогая им анализировать производительность операционной системы и приложений, устранять неполадки кода и повышать безопасность. "BPF Performance Tools: наблюдаемость системы и приложений Linux" - наиболее полное в отрасли руководство по использованию этих инструментов для наблюдаемости. Брендан Грегг, автор отраслевого руководства по производительности системы, представляет новые мощные методы и инструменты для проведения анализа, которые ведут к созданию более надежного, надежного и безопасного кода.

BPF and related observability tools give software professionals unprecedented visibility into software, helping them analyze operating system and application performance, troubleshoot code, and strengthen security. BPF Performance Tools: Linux System and Application Observability is the industry’s most comprehensive guide to using these tools for observability. Brendan Gregg, author of the industry’s definitive guide to system performance, introduces powerful new methods and tools for doing analysis that leads to more robust, reliable, and safer code.

This authoritative guide:

Explores a wide spectrum of software and hardware targets
Thoroughly covers open source BPF tools from the Linux Foundation iovisor project’s bcc and bpftrace repositories
Summarizes performance engineering and kernel internals you need to understand
Provides and discusses 150+ bpftrace tools, including 80 written specifically for this book: tools you can run as-is, without programming — or customize and develop further, using diverse interfaces and the bpftrace front-end

Why Do You Need BPF Performance Tools?
These tools can help you get the most out of your systems and applications, helping you improve performance, reduce costs, and solve software issues. They can analyze much further than traditional tools, and allow you to pose arbitrary questions of the system and get answers immediately, in production environments.

You’ll learn how to use BPF (eBPF) tracing tools to analyze CPUs, memory, disks, file systems, networking, languages, applications, containers, hypervisors, security, and the Linux kernel. You’ll move from basic to advanced tools and techniques, producing new metrics, stack traces, custom latency histograms, and more. It’s like having a superpower: with Gregg’s guidance and tools, you can analyze virtually everything that impacts system performance, so you can improve virtually any Linux operating system or application.
