DTrace: Managing Applications in Modern Operating Systems
Abstract: Modern operating systems often have many commands at different layers in the software stack which are required in order to debug issues. DTrace changes this and provides a secure single interface to investigate nearly every layer in the software stack in a running production system, where developers can even create their own hooks for when they may need additional future insight.
