Chapter 1 About DTrace

DTrace is a comprehensive dynamic tracing facility that is built into Oracle Linux that can be used by administrators and developers on live production systems to examine the behavior of user programs and the operating system. DTrace enables you to explore your system to understand how it works, track down performance problems, or locate the cause of aberrant behavior. DTrace lets you create your own custom programs to dynamically instrument the system and provide immediate, concise answers to arbitrary questions you can formulate using the DTrace D programming language.

For information about how to obtain, install, and use the DTrace software, see the Oracle Linux DTrace Tutorial.
