The official DTrace guide

This guide has been around for quite some time, but I still wanted to write about it here.

Here is the link: Solaris Dynamic Tracing Guide

This guide has lots of very simple and useful examples, so it's a good starting point.

All these examples can be found in /usr/demo/dtrace, and if you open /usr/demo/dtrace/index.html in your browser, you'll see all the examples in a table, split by the guide chapters.
