Synopses & Reviews

Publisher Comments:

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.

Book News Annotation:

This voluminous guide to DTrace, Oracle's Solaris dynamic tracing application, provides instruction for systems administrators, programmers and students on using this information and debugging tool to understand and improve the efficiency of applications and computer systems. The work is divided into three sections covering the basics of the D language syntax, a detailed explanation of the many uses of DTrace commands and scripts and advanced topics including kernel debugging, security and tips and tricks. The volume includes numerous code examples as well as a collection of appendices that document specific variables, argument and error messages as well "cheat sheet" documents. Access to additional online resources, including all of the scripts described in the text, is provided. Gregg is the developer of the popular DTrace Toolkit and Mauro is a senior engineer at Oracle.

Synopsis:

The first guide to DTrace: the breakthrough debugging tool for Mac OS X, Unix, Solaris, and OpenSolaris operating systems and applications

 

  • Complete coverage: architecture, implementation, components, usage, and much more
  • Covers integrating DTrace into open source code, and integrating probes into application software
  • Includes full chapter of advanced tips and techniques
  • For users of DTrace on all platforms
  • Foreword by Bryan Cantril, creator of DTrace
  •  

     DTrace represents a revolution in debugging. Using it, administrators, developers, and service personnel can dynamically instrument operating systems and applications to quickly ask and answer virtually any question about how their operating systems or user programs are behaving. Now available for Solaris 10 and OpenSolaris, Mac OS X, and FreeBSD, thousands of professionals are discovering DTrace - but, until now, there's been no comprehensive, authoritative guide to using it. This book fills that gap. Written by four key contributors to the DTrace community, it's the first single source reference to this powerful new technology. The authors cover everything technical professionals need to know to succeed with DTrace, regardless of the operating system or application they want to instrument. The book also includes a full chapter of advanced tips and techniques.
