Open Source Mac Profiling Software

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.

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.

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.

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.

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

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

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.

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.

Java Collection Size Profiler. Use CProfiler to get traces of collection sizes of dynamically instrumented Java programs.

iostat is a tool for the creation of IO statistics of precompiled binaries in Unix like systems (Linux/MacOS).

.Net Memory Profiler is a single C# class that builds a tree of specified object's fields, their sub-fields and so on up to primitive types. And in the "Quick Watch" window of the Visual Studio you will be able to see the memory usage by each of those fields. For more details see screenshots.

Implementation of Aspect Oriented Programming (AOP) for Erlang. The AOP weaver is running against a target set of source files and controlled by aspect definitions. The weaver is implemented as a parse transformation function of Erlang compiler.

ASGMemProf is an exact, bytecode instrumenting memory profiler for Java EE, relying on a novel scheme - memory accounts.

Application Management makes your application life easier. Automatic do memory management, handle and log unhandled exceptions, profiling your functions, make your application single instance and also provide util functions to get system information.

Library for dynamic tuning of program parameters for best performance of program.

BeCover is a Java code coverage tool based on source-code analysis. The main goal is to keep it small and fast, so using it as a plugin in the common IDE's can be achieved.

Z80 ASM editor that gives you real-time info about Mnemonics, Waitstates/Clock cycles, and Labels. Features code completion, real-time debugging and T-states profiling.
