DTrace represents a revolution in debugging. Using it, administrators, developers, and service personnel can dynamically instrument operating systems and applications to quickly ask and answer virtually any question about how their operating systems or user programs are behaving. Now available for Solaris 10 and OpenSolaris, Mac OS X, and FreeBSD, thousands of professionals are discovering DTrace - but, until now, there's been no comprehensive, authoritative guide to using it. This book fills that gap. Written by four key contributors to the DTrace community, it's the first single source reference to this powerful new technology. The authors cover everything technical professionals need to know to succeed with DTrace, regardless of the operating system or application they want to instrument. The book also includes a full chapter of advanced tips and techniques.
