LISA2019 Linux Systems PerformanceBrendan Gregg

Talk by Brendan Gregg for USENIX LISA 2019: Linux Systems Performance. Abstract: " Systems performance is an effective discipline for performance analysis and tuning, and can help you find performance wins for your applications and the kernel. However, most of us are not performance or kernel engineers, and have limited time to study this topic. This talk summarizes the topic for everyone, touring six important areas of Linux systems performance: observability tools, methodologies, benchmarking, profiling, tracing, and tuning. Included are recipes for Linux performance analysis and tuning (using vmstat, mpstat, iostat, etc), overviews of complex areas including profiling (perf_events) and tracing (Ftrace, bcc/BPF, and bpftrace/BPF), and much advice about what is and isn't important to learn. This talk is aimed at everyone: developers, operations, sysadmins, etc, and in any environment running Linux, bare metal or the cloud."

OSDC 2017 - Werner Fischer - Linux performance profiling and monitoringNETWAYS

Nowadays system administrators have great choices when it comes down to Linux performance profiling and monitoring. The challenge is to pick the appropriate tools and interpret their results correctly. This talk is a chance to take a tour through various performance profiling and benchmarking tools, focusing on their benefit for every sysadmin. More than 25 different tools are presented. Ranging from well known tools like strace, iostat, tcpdump or vmstat to new features like Linux tracepoints or perf_events. You will also learn which tools can be monitored by Icinga and which monitoring plugins are already available for that. At the end the goal is to gather reference points to look at, whenever you are faced with performance problems. Take the chance to close your knowledge gaps and learn how to get the most out of your system.

Как понять, что происходит на сервере? / Александр Крижановский (NatSys Lab.,...Ontico

Запускаем сервер (БД, Web-сервер или что-то свое собственное) и не получаем желаемый RPS. Запускаем top и видим, что 100% выедается CPU. Что дальше, на что расходуется процессорное время? Можно ли подкрутить какие-то ручки, чтобы улучшить производительность? А если параметр CPU не высокий, то куда смотреть дальше? Мы рассмотрим несколько сценариев проблем производительности, рассмотрим доступные инструменты анализа производительности и разберемся в методологии оптимизации производительности Linux, ответим на вопрос за какие ручки и как крутить.

Debugging linux issues with eBPFIvan Babrou

Presented at LISA18: https://www.usenix.org/conference/lisa18/presentation/babrou This is a technical dive into how we used eBPF to solve real-world issues uncovered during an innocent OS upgrade. We'll see how we debugged 10x CPU increase in Kafka after Debian upgrade and what lessons we learned. We'll get from high-level effects like increased CPU to flamegraphs showing us where the problem lies to tracing timers and functions calls in the Linux kernel. The focus is on tools what operational engineers can use to debug performance issues in production. This particular issue happened at Cloudflare on a Kafka cluster doing 100Gbps of ingress and many multiple of that egress.

44CON London 2015 - Jtagsploitation: 5 wires, 5 ways to root44CON

The document discusses 5 ways to exploit JTAG (Joint Test Action Group) interfaces to gain unauthorized access or privileges on a system. The 5 techniques are: 1) Accessing non-volatile storage like flash memory via boundary scan, 2) Scraping memory for offline forensic analysis, 3) Patching boot arguments to change how the system boots, 4) Directly patching the kernel by modifying code or function pointers in memory, and 5) Patching a specific process by searching memory for its code and modifying it. While some techniques like memory scraping are slow, others like boot argument patching or kernel patching can be done quickly and provide privileged access. JTAG interfaces provide I/O, execution control, and memory access that enable

Kernel Recipes 2017: Performance Analysis with BPFBrendan Gregg

Talk by Brendan Gregg at Kernel Recipes 2017 (Paris): "The in-kernel Berkeley Packet Filter (BPF) has been enhanced in recent kernels to do much more than just filtering packets. It can now run user-defined programs on events, such as on tracepoints, kprobes, uprobes, and perf_events, allowing advanced performance analysis tools to be created. These can be used in production as the BPF virtual machine is sandboxed and will reject unsafe code, and are already in use at Netflix. Beginning with the bpf() syscall in 3.18, enhancements have been added in many kernel versions since, with major features for BPF analysis landing in Linux 4.1, 4.4, 4.7, and 4.9. Specific capabilities these provide include custom in-kernel summaries of metrics, custom latency measurements, and frequency counting kernel and user stack traces on events. One interesting case involves saving stack traces on wake up events, and associating them with the blocked stack trace: so that we can see the blocking stack trace and the waker together, merged in kernel by a BPF program (that particular example is in the kernel as samples/bpf/offwaketime). This talk will discuss the new BPF capabilities for performance analysis and debugging, and demonstrate the new open source tools that have been developed to use it, many of which are in the Linux Foundation iovisor bcc (BPF Compiler Collection) project. These include tools to analyze the CPU scheduler, TCP performance, file system performance, block I/O, and more."
