註釋Abstract: "Systems for recording address traces of operating system activity have frequently relied on special-purpose hardware and microcode modifications for data collection [1,2,10,11,30,32]. In the last decade, changes in computer systems design have made the implementation of such hardware and microcode-based tracing systems impractical. This paper documents the evolution of a group of software methods to collect system traces. The tools require no special-purpose hardware and no hardware modifications. We have applied these tools to three substantially different operating systems and two processor architectures. This paper describes the instrumentation techniques, the means used to assure the quality of the collected data, and our evaluation of correctness and accuracy of traces. Our experience shows that software methods can yield trace of very good quality, and can be used to measure complex software systems."
