Perf is powerful and low-overhead profiling/tracing tool. It can analyse not only kernel but also userspace programs. This presentation will mainly focus userspace program analysis and show advantages and problems by introducing a use-case. In operation phase of enterprise systems, accountability is one of most important thing. When the system causes panic or slowdown, we must analyse it and show the evidence. Since the reason of failure is various, the tool which can be analyzed integrative is important for it. We think that perf is excellent in such a case.

The presentation is mainly targeted at support enginneers, program developers and system operators. Knowledge of program analysis technologies such as profiling, tracer, executable file format(elf and dwarf) is advantageous, but not required.
