OProfile is a system-wide profiler for Linux systems,
capable of profiling all running code at low overhead.
OProfile is released under the GNU GPL.
It consists of a kernel driver and a daemon for collecting
sample data, and several post-profiling tools for turning
data into information.
OProfile leverages the hardware performance counters of the
CPU to enable profiling of a wide variety of interesting
statistics, which can also be used for basic time-spent
profiling. All code is profiled: hardware and software
interrupt handlers, kernel modules, the kernel, shared
libraries, and applications.
