摘要

The upcoming version of sun microsystems inc.'s flagship operating system, Solaris 10, will be the most feature-packed release in some time. One compelling new Solaris component is DTrace, a facility that opens to developers and system administrators a window onto the workings of the operating system and the applications that run on it. DTrace lets administrators see the same systemwide diagnostic information that current tools such as Surfs truss show, but DTrace also allows users to get as fine-grained a level of detail as they require, providing an exploded view of system calls, application function calls and instructions executed by running programs. What's more, DTrace does so dynamically; it does not require that examined applications be stopped, nor does it require modifications to the code it examines.
