Dtrace Dynamic Tracing In Oracle Solaris Mac Os X And Freebsd

DTrace

The Oracle Solaris DTrace feature revolutionizes the way you debug operating systems and applications. Using DTrace, you can dynamically instrument software and quickly answer virtually any question about its behavior. Now, for the first time, there's a comprehensive, authoritative guide to making the most of DTrace in any supported UNIX environment--from Oracle Solaris to OpenSolaris, Mac OS X, and FreeBSD. Written by key contributors to the DTrace community, DTrace teaches by example, presenting scores of commands and easy-to-adapt, downloadable D scripts. These concise examples generate answers to real and useful questions, and serve as a starting point for building more complex scripts. Using them, you can start making practical use of DTrace immediately, whether you're an administrator, developer, analyst, architect, or support professional. The authors fully explain the goals, techniques, and output associated with each script or command. Drawing on their extensive experience, they provide strategy suggestions, checklists, and functional diagrams, as well as a chapter of advanced tips and tricks. You'll learn how to Write effective scripts using DTrace's D language Use DTrace to thoroughly understand system performance Expose functional areas of the operating system, including I/O, filesystems, and protocols Use DTrace in the application and database development process Identify and fix security problems with DTrace Analyze the operating system kernel Integrate DTrace into source code Extend DTrace with other tools This book will help you make the most of DTrace to solve problems more quickly and efficiently, and build systems that work faster and more reliably.

The Kollected Kode Vicious

Pragmatic, Bite-Sized Programming Advice from Koder-with-Attitude, Kode Vicious “For many years I have been a fan of the regular columns by Kode Vicious in Communications of the ACM. The topics are not only timely, they're explained with wit and elegance.” --From the Foreword by Donald E. Knuth Writing as Kode Vicious (KV), George V. Neville-Neil has spent more than 15 years sharing incisive advice and fierce insights for everyone who codes, works with code, or works with coders. Now, in The Kollected Kode Vicious, he has brought together his best essays and Socratic dialogues on the topic of building more effective computer systems. These columns have been among the most popular items published in ACM Queue magazine, as well as Communications of the ACM, and KV's entertaining and perceptive explorations are supplemented here with new material that illuminates broader themes and addresses issues relevant to every software professional. Neville-Neil cuts to the heart of the matter and offers practical takeaways for newcomers and veterans alike on the following topics: The Kode at Hand: What to do (or not to do) with a specific piece of code Koding Konundrums: Issues that surround code, such as testing and documentation Systems Design: Overall systems design topics, from abstraction and threads to security Machine to Machine: Distributed systems and computer networking Human to Human: Dealing with developers, managers, and other people Each chapter brings together letters, responses, and advice that apply directly to day-to-day problems faced by those who work in or with computing systems. While the answers to the questions posed are always written with an eye towards humor, the advice given is deadly serious.
