“Solaris Internals” and its predecessor “Sun Performance and Tuning” are wonderful books for giving you the knowledge to know whats actually happening under the covers, but many SA’s admit struggling when it comes to translating that into usable day-to-day understanding of the systems on which they manage. Just knowing how it works isn’t enough to be really useful, what you need is the ability to look at the system and work out how what your seeing fits what you know.
“Solaris Performance and Tools” bridges that gap. Every page, cover-to-cover is filled with practical examples and explanations of the tools that let you actually see what Solaris is doing. If you’ve tended to rely on only a handful of tools such as vmstat, iostat, netstat, sar, and prstat, then you really want to get this book and start digging much deeper. Even as a Sr Admin I found that there were wonderful tools available that I didn’t even know existed (such as “intrstat”).
In particular, this book unlocks two powerful tools in Solaris 10 that can be as complex as they are powerful: DTrace and mdb. Both of these give you unparalleled power to dig your fingers into the system, but using them beyond simple one liners is more difficult than most people admin. This book gives you a great step-by-step approach to learning both. While a one-line DTrace script found in a blog might help you here and there, you won’t truly understand how powerful DTrace can be untill you’ve built
a firm foundation on which to build your own. This book is the best way to jump start that process.
This truly is the only book available that opens the window to whats possible in Solaris in such a practical way. You’ll find things you didn’t know, you’ll start understanding how things work by putting practical numbers on YOUR system together with the knowledge you aquired from “Solaris Internals” and you’ll start solving problems rathan than just knowing why somethings broken or slow.
