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.
