An Overview of DTrace DTrace is a comprehensive dynamic tracing framework for the Solaris™ Operating Environment. DTrace provides a powerful infrastructure to permit administrators, developers, and service personnel to concisely answer arbitrary questions about the behavior of the operating system and user programs. The Solaris™ Dynamic Tracing Guide describes how to use DTrace to observe, debug and tune system behavior. The Solaris™ Dynamic Tracing (DTrace) Guide (here), also includes a complete reference for bundled DTrace observability tools and the D programming language. For Users: dynamically enable and manage thousands of probes dynamically associate predicates and actions with probes dynamically manage trace buffers and probe overhead examine trace data from a live system or from a system crash dump For Solaris™ Developers: implement new trace data providers that plug into DTrace implement trace data consumers that provide data display implement tools that configure DTrace probes For more information check out the out scripts and documentation.
