OProfile 1.0.0 RC2
It is best described as unobtrusive
OProfile is capable of instruction-grain profiling of shared libraries, all processes, the kernel, as well as all the device drivers, through the hardware performance counters. It is best described as unobtrusive, provides supports for call-graph, post-profile analysis, and performance counter.
Works well across a wide range of processors
The software works well across a wide range of processors, including Intel, ARM, AMD's Athlon and AMD64 processors, Alpha, and more. It supports both SMP and UP systems, and runs perfectly on 32-bit (x86) and 64-bit (x86_64) hardware platforms.
It’s a non-interactive daemon
As mentioned, OProfile is a command-line software that runs in the background, as a non-interactive daemon. It starts automatically when the computers boots and supports both Linux and BSD operating systems.
A good profiling tool
During our tests, which we have to admit that they were run on a couple of GNU/Linux distributions (this means that we didn’t tested on any BSD operating system), OProfile proved to be a good profiling tool.
Under the hood and availability
The program is written entirely in the widely used C and C++ programming languages. It can be downloaded via Softpedia or directly from its homepage (see link above) as a source archive, which can run on a wide range of Linux distributions or BSD flavors.
Whether you are a system administrator or a developer in search for a transparent profiler for Linux, you can grab and install the OProfile software right now using the download link above. We guarantee that you won’t regret it.
