OProfile has been around for decades, and for some time was the workhorse of performance profiling on Linux®-based systems, and can serve the same role today. However, OProfile is not included in Red Hat Enterprise Linux (RHEL) 8 beta, and so it may be prudent for OProfile users to start considering alternative tools. Analogous projects which compare very favorably to OProfile in features, ease-of-use, and vitality of the community do exist. One such project is the Linux perf command. Until recently, when compared to OProfile, perf had some drawbacks such as lack of support for Java™ just-in-time (JIT) compiled programs and hardware event mnemonics, but these have been addressed in recent releases. This tutorial offers current OProfile users a roadmap for transitioning from OProfile to perf.
