Brendan Gregg 目前是 Netflix 的高级性能架构师 ,他在那里做大规模计算机性能设计、分析和调优。他是《Systems Performance》等技术书的作者,因在系统管理员方面的成绩,获得过 2013年 USENIX LISA 大奖。他之前是 SUN 公司是性能领头人和内核工程师,他在 SUN 开发过 ZFS L2ARC,研究存储和网络性能。他也发明和开发过一大波性能分析工具,很多已集成到操作系统中了 。他的最近工作包括研究性能分析的方法论和可视化,其目标包括Linux内核。

上面这是 Gregg 的简介,正如其中说的,他个人站点上分享了很多 Linux 性能相关的资源,都是自己开发的:

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 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.
