Ph.D. dissertation: Low-Impact Operating System Tracing

Mathieu Desnoyers has posted his Ph.D. dissertation as a 233-page PDF file. "In this thesis, we propose the LTTng (Linux Trace Toolkit next generation) tracer as an answer to the industry and open source community tracing needs. The low-intrusiveness of the tracer is a key aspect to its usefulness, because we need to be able to reproduce, under tracing, problems occurring in normal conditions. In some cases, users leave tracers active at all times in production, which makes the tracer overhead definitely critical."
