Do not let the size daunts you however Chapters are self contained, as the author understands that the book might be read under pressure, and contain useful exercises at the end.
What really makes this book stands out, is not the top notch technical writing or abundance of useful one liners, is the fact that the author moves forward and suggests a methodology for troubleshooting and performance analysis, as opposed to the ad hoc methods of the past or best case scenario a checklist and DEITY forbid the use of blame someone else methodology In particular the author suggests the USE methodology, USE standing for Utilization Saturation Errors, to methodically and accurately analyze and diagnose problems This methodology which can be adapted expanded at will, last time I checked the book was not written in stone , is worth the pr Great book for any Linux Operations guys out there to test and determine metrics for your infrastructure.
Grail of performance issues improvements.
Though at risk of being a tad ranty about how Solaris is better than linux, Brendan Gregg s detail and understanding of Kernel development and performance is comprehensive and both introduces the topic and then guides the reader through how to measure it It s a must read for Linux developers.
,.
Brings down performance analysis to actual commands and methodologies you can directly use Quite nice read.
Highly recommended I bought and started to read this book to prepare myself for a job interview Really recommendable.
Ps I finally got the job
