Books
Systems Performance: Enterprise and the Cloud 2nd Edition, 2020
Brendan Gregg. ISBN 978-0-13-682015-4. Addison-Wesley.
Development in progress.
BPF Performance Tools: Linux System and Application Observability, 2019
Brendan Gregg. ISBN 0-13-655482-2. Addison-Wesley.
BPF originally stood for Berkeley Packet Filter, but has been extended to be an in-kernel execution environment in Linux, allowing a new type of software to be developed. This includes a new era of observability tools.
The book includes over 150 BPF observability tools that you can run to find performance wins and troubleshoot software, and also shows you how to write your own. Over one hundred of these BPF tools are newly-developed for this book.
Systems Performance: Enterprise and the Cloud, 2013
Brendan Gregg. ISBN 0-13-339009-8. Prentice Hall.See the book website and the sample chapter on CPUs.
This book covers new developments in systems performance: in particular, dynamic tracing and cloud computing. It also introduces many new methodologies to help a wide audience get started. It leads with Linux examples from Ubuntu, Fedora, and CentOS, and also covers Solaris-based distributions. Covering two different kernels provides additional perspective that enhances the reader's understanding of each. The book is 635 pages plus appendices.
DTrace: Dynamic Tracing in Oracle Solaris, Mac OS X and FreeBSD, 2011
Brendan Gregg, Jim Mauro. ISBN 0132091518. Prentice Hall.See the TOC and File Systems sample chapter.
This shows how to use DTrace by-example for performance analysis and troubleshooting. Solaris was used as the primary OS, with additional examples from Mac OS X and FreeBSD. The most difficult challenge for using a dynamic tracing tool (DTrace, SystemTap, etc.) is knowing what to do with it. This book provides over one hundred use cases (scripts), which will be invaluable even after the example code becomes out of date. 1152 pages.
Solaris Performance and Tools: DTrace and MDB Techniques for Solaris 10 and OpenSolaris, 2006
Richard McDougall, Jim Mauro, Brendan Gregg. ASIN 0131568191. Prentice Hall. Numberballs mac os.
A practical guide to performance analysis on Solaris. This summarizes background for context, and shows how to use the various tools available. This book was written at an interesting time: DTrace was new, filling in many observability gaps, and this book covers the best of the old and new ways of analysis. It was written as a companion volume to Solaris Internals 2nd Edition, which it references.
