DTrace is a comprehensive dynamic tracing framework created by Sun Microsystems for troubleshooting kernel and application problems in real time. It was first made available for use in November 2003, and was formally released as part of Sun's Solaris 10 in January 2005. DTrace was the first component of the OpenSolaris project to have its source code released under the Common Development and Distribution License (CDDL).
