Open Source Java Profiling Software

(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.

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.

JIP is a high performance, low overhead profiler that is written entirely in Java. JIP gives the developer the ability to turn the profiler on and off while the VM is running. You can also filter out classes and packages as well as control the output.

Jensor is a light-weight, low-overhead Java Profiler built using Java BCI. Jensor provides innovative analysis modules like JVM Replay, Pattern Analysis and Tagging Engine for technical as well as business analysis based on the same underlying data.

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

ParTools allows the interactive analysis of a C program execution profile and data dependencies to facilitate the discovery and selection of suitable parallelization candidates in a manual parallelization process. The flow does not assume any specific parallelization technique, thus it can be broadly applied. The original (serial) C source is automatically annotated to trace the execution profile and data dependencies at run-time. The annotated program is then executed using a significant (but small) data set selected by the developer. The data collected is cross-referenced with the original source and can be interactively analyzed graphically to determine the best parallelization candidates and techniques.

This profiler (JRE 1.5.0 only) uses JVMTI and native bytecode instrumentation for the analysis of the heap, reachable objects, execution time, garbage collection efficiency, code coverage and thread contention. No preparation steps required in build.

Jarrut is a tool that makes developing and debugging Java ME applications (application using CLDC to be more specific) a bit less of a pain. Jarrut enables proper stack traces for exceptions, also when running a MIDlet on a real device

Kieker is a framework for continuous monitoring and dynamic analysis of distributed software systems. Being designed for continuous operation, it induces only a low overhead. The TraceAnalysis tool allows to analyze and visualize trace information.

Elvyx is a tool designed to monitor and profile the jdbc activity on java projects. This jdbc profiler has a server with a built-in db and a client to improve the experience.

Stopwatch is a simple, highly extensible, API that alows monitoring of any part of the application. It reports hits, execution times and load but can be extended to do more via custom engines. It is able to persist data in "in-memory" or real database.

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.

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.

An adaptable, platform-agnostic application incident reporting infrastructure ranging from logging libs and webservice-based reporting to a J2EE logging server to a pluggable connection to issuemanagers.

Approximate Reasoning trades completeness and soundness for increasing speed. The focus of this project is to develop scalable reasoning techniques for OWL ontologies.

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

ASLA (Automated software license analyzer) is a tool for finding and identifying licenses of existing software packages.

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 ;-)

An implementation of the Open Group's Application Response Measurement (ARM) Version 4 standard. The ARM standard describes a means of breaking an application down into it's constituent transactions, and measuring response time across multiple tiers.

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.

Simple and easy to use Java Application Performance Monitoring tools It shows latency time, cpu usage time in each node in your application. The data will be decorated with MS-Excel Pivot table feature into your view.

COMPAS J2EE is a non-intrusive performance instrumentation and monitoring toolkit for J2EE. It uses adaptive monitoring to automatically adjust the target coverage. COMPAS is completely portable across J2EE application servers and OSs.

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

ClassReach is a utility to identify unused Java classes and methods. Once identified, such things can be removed from the code, hopefully simplifying the system.

CodeSleuth is an Eclipse plug-in that exposes CPU performance data and maps that information to the code emitted by the JVM, and then to the Java source. This data allows Java developers to analyze and modify the code to improve application performance.
