Modern OS and CPUs come with a variaty of APIs for monitoring. Ptrace based commands like strace are easy to use but slow. Perf allows lightweight profiling. SystemTap is a powerfil toolkit plus DSL to instrument probe points inside the Kernel as well as static SystemTap/DTrace markers in libs and languages like Java, PHP, and Python. In my talk I'll show and compare various low and high level tools as well as visualization tools, e.g. how to create flame graph.
