In computing, OProfile is a system-wide statistical profiling tool for Linux.John Levon wrote it in 2001 for Linux kernel version 2.4 after his M.Sc. project; it consists of a kernel module, a user-space daemon and several user-space tools.. OProfile can profile an entire system or its parts, from interrupt routines or drivers, to user-space processes.It has low overhead.License: GPL

Yes, starting with OProfile 0.8 and kernel version 2.6, callgraph support is available on many (but not all) architectures, such as x86, ARM, and ppc/ppc64. What about the "security hole" CVE-2006-0576? This "problem" only occurs if you actively, and mistakenly, configure access to OProfile via sudo.

Performance counter support Enables collection of various low-level data, and assocation with particular sections of code. Call-graph support With an x86 or ARM 2.6 kernel, OProfile can provide gprof-style call-graph profiling data. Low overhead OProfile has a typical overhead of 1-8%, dependent on sampling frequency and workload. Post-profile ...

Analyzing the performance of the Linux operating system and application code can be difficult due to unexpected interactions between the hardware and the software, but profiling is one way you can identify such performance problems. This article looks at OProfile, a profiling tool for Linux that will be included in the upcoming stable kernel.

Overview. OProfile is a system-wide Linux profiler, capable of running at low overhead. It consists of a kernel driver and a daemon for collecting raw sample data, along with a suite of tools for parsing that data into meaningful information.

Before OProfile can be run, it must be configured. At a minimum, selecting to monitor the kernel (or selecting not to monitor the kernel) is required. The following sections describe how to use the opcontrol utility to configure OProfile. As the opcontrol commands are executed, the setup options are saved to the /root/.oprofile/daemonrc file.
