Hands-On System Programming with Linux

By: Kaiwan N. Billimoria, Tigran Aivazian

Overview of this book

The Linux OS and its embedded and server applications are critical components of today’s software infrastructure in a decentralized, networked universe. The industry's demand for proficient Linux developers is only rising with time. Hands-On System Programming with Linux gives you a solid theoretical base and practical industry-relevant descriptions, and covers the Linux system programming domain. It delves into the art and science of Linux application programming— system architecture, process memory and management, signaling, timers, pthreads, and file IO. This book goes beyond the use API X to do Y approach; it explains the concepts and theories required to understand programming interfaces and design decisions, the tradeoffs made by experienced developers when using them, and the rationale behind them. Troubleshooting tips and techniques are included in the concluding chapter. By the end of this book, you will have gained essential conceptual design knowledge and hands-on experience working with Linux system programming interfaces.

Troubleshooting tools

In this section, we will mention several tools and utilities that can help the application developer identify system bottlenecks and performance issues. (Note that here, to save space and time, we do not delve into the dozens of usual suspects—well-known system monitoring utilities on Linux such as ps, pstree, top, htop, pidstat, vmstat, dstat, sar, nagios, iotop, iostat, ionice, lsof, nmon, iftop, ethtool, netstat, tcpdump, wireshark—and instead mention the newer ones). Here is an important thing to remember when performing data collection (or benchmarking) for later analysis: take the trouble to set up a test rig and, when using it, change (as far as is possible) only one variable at a time for a given run so that you can see its impact.
