Open Source Linux Profiling Software

The goal of the project is now to develop a user library called libpfm4 to help setup performance events for use with the perf_events Linux kernel interface. The development of the perfmon kernel subsystem, libpfm and pfmon has now stopped.

OProfile is a low-overhead, transparent profiler for Linux, capable of instruction-grain profiling of all processes, shared libraries, the kernel and device drivers, via the hardware performance counters.

py-spy is a sampling profiler for Python programs. It lets you visualize what your Python program is spending time on without restarting the program or modifying the code in any way. py-spy is extremely low overhead: it is written in Rust for speed and doesn't run in the same process as the profiled Python program. This means py-spy is safe to use against production Python code. py-spy works from the command line and takes either the PID of the program you want to sample from or the command line of the python program you want to run. py-spy has three subcommands record, top and dump. py-spy supports recording profiles to a file using the record command. Top shows a live view of what functions are taking the most time in your python program, similar to the Unix top command.

cloc (Count Lines Of Code) counts, and computes differences of, comment lines, blank lines, and physical lines of source code in many programming languages. cloc is now being developed at https://github.com/AlDanial/cloc

ebizzy is designed to generate a workload resembling common web application server workloads. It is highly threaded, has a large in-memory working set, and allocates and deallocates memory frequently.

This benchmark suite is intend as a tool for the research community. It consists of a set of open source, real world applications with non-trivial memory loads.

(Diver is in the process of being moved to GitHub. Please find us at https://github.com/thechiselgroup/Diver. Support requests & messages sent here may never be seen.) Dynamic Interactive Views For Reverse Engineering. Div/er is a set of Eclipse Plugins that aid developers in understanding software. It uses dynamic analysis and reverse engineering to offer views and filters that aid comprehension and discovery.

Cinemagoer is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies. Platform-independent, it can retrieve data from both the IMDb's web server and a local copy of the whole db.

Glassbox is an automated troubleshooting and monitoring agent for Java apps that diagnoses common problems with one-click. Drop in a .war file from http://www.glassbox.com and find out what's wrong with your existing web apps, without any code chang

Jwebap is an profiler tool for j2ee application with jdk 1.4 and up.You can use it to monitor method,jdbc,jsp executions etc.And then view in a web console.It can be used not only in test environment but production environment with very low-overhead.

SLOCCount is an easy-to-use tool that counts Source Lines of Code (SLOC). It auto-determines the language(s) (inc. C, C++, Ada, Assembly, shell, COBOL, C#, Fortran, Haskell, Java, LISP/Scheme, Perl, PHP, Python, Ruby, SQL). It also estimates cost & time.

The Performance Inspector package contains a suite of performance analysis tools for Linux, Windows, AIX, and zOS with an emphasis on Java profiling.

Volta is a suite of development tools for distributed, hard real-time systems. It includes Cascade, a control flow analysis tool for Java, and Clepsydra, a worst-case execution time analyzer. Also included is a Clepsydra plug-in for jEdit.

TimeDoctor is a tool to visualize execution traces of tasks, queues, cache behavior, etc. While originally targeting embedded media processors and includes specific features for analyzing audio/video streaming applications it has wider applicability.

KCachegrind visualizes traces generated by profiling, including a tree map and a call graph visualization of the calls happening. It's designed to be fast for very large programs like KDE applications.

Developer tool for automatic runtime tracing software errors with various resources. Number of resources virtually unlimited.

Welcome to IgProf, the ignominious profiler. IgProf is a simple nice tool for measuring and analysing application memory and performance characteristics. IgProf requires no changes to the application or the build process.

A very simple implementation of C++ keyword sizeof for Java 5+. Developers can use it to know the real size of objects in memory.

Appspy is a user experience profiling tool. With Appspy you will be able to know what your users are doing. Be careful, this may result in dramatic improvements of your software ;-)

Madmap is a tool to help analyze java heap dumps. New in v1.1 it supports hprof ascii and now binary dumps collected with jmap. It helps find memory leaks by showing the live set and automatically calculating which objects retain the most heap size.

"It's not a tool, which fixes a problem, but the fool using it!" (Jörg Stryk) The M7 bunch of scripts should help the EXPERIENCED Troubleshooter to quickly identify bottlenecks and to develop/implement appropriate solutions. "With great power comes great responsibility" (Uncle Ben)

What is QProf ? QProf is a visual tool for developers, which displays the execution profiling output generated by code profilers. The output of profilers being usually difficult to read (beyond the flat profile information), QProf presents the information in list- or tree-views that make the information very easy to understand. This project was ported from KProf (Qt3/KDE) project.

Vogoo PHP LIB is a powerful collaborative filtering engine that allows Webmasters to easily add high personalisation features to their Web Sites.

MonitorJMX is a very small web application capable to monitor WebLogic Servers/Cluster using a single JMX connection. Two JSP dashboards are available in this first version: servers and jms.

This is a dynamic slicing tool for Java programs. The tool modifies the Kaffe virtual machine to collect the execution trace, and compress the trace on-the-fly. Please proceed to the tool's website http://jslice.sourceforge.net/ for download.
