JSnapshot is an advanced java exception logging, monitoring and analysis tool. It traces thrown exceptions in real-time and logs a snapshot of call stack, variables and objects for every thrown exception. Fully integrated with Eclipse IDE.
JSpoor is a utility software for logging and recording of user interface events and actions during working sessions of users with a Java/Swing Software. It captures and records both high level (semantic) actions and low level actions such as mouse moves.
JSysmon is a Java library providing access to system information like CPU or Memory usage on various platforms using native calls. It can be used to build cross-platform monitors in your applications.
JTimeIt is a small framework for writing and running performance tests of Java sourcecode. It's 100% Java, which provides the opportunity of platform-independent performance tests. Additionally, it supports the measurement of JUnit Tests.
JTombstone is a program for finding dead code in your Java programs. It reports on dead code at the method level, by processing Java class files. No source code is needed to use it. JTombstone is a Java program and requires JDK 1.4 or later.
The open source profiler for the jvm.
Get an inside view of your application. Find bottlenecks by looking at the development of the duration of your main business methods over time even in production. Find the cause of those bottlenecks by applying the profiling capabilities of JVMLense.
JAva Fault Injection and MONitoring tool
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
Java class profiler
Minimalistic java profiler using instrumentation and asm libs to preform a measure of the time spent by methods. Mesure is efficient until the micro second and very realistic on milli second. The ui allows exports, remote connection and multiple connections.
A collection of light-weight utilities for diagnosing, monitoring, testing, and fixing production Java web apps.
Jdptool is a debug and profiler tool which based on JPDA; It provide both swing based and browser based GUI. It has sophisticated debugger without user interfere. It also provide profiler to memory usage and threads with numerous new feature
Jetrace is a Java Enterprise trace tool that J2EE developers and architects can use to discover erroneous execution flows in JSPs, Servlets, EJBs, JNDI calls, JDBC calls and sockets. It can be used to validate both code and design and to troubleshoot.
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.
Kernel Analyzer is tool for Linux that monitor task preemptions and interruptions in the Linux Kernel. Basically it is a Kernel Patch, that comes also with a user proc interface, a KDB interface, and a Java GUI to display charts.
Lack of Progress Bar (Lopb) is an Eclipse plugin that tracks how long developers wait for file check-ins/outs, code compilation, publishing apps to a web server, and other IDE background jobs to complete. Read more at http://lopb.org
This project aims at being the spearhead of logging tools. It will integrate with existing logging frameworks and will incorporate unique features to maximize speed and usability.

The project aims to develop an application which monitors the system performance with different virtual memory and scheduler parameters and publish a comparitive study of the same.
Monitors webpages for changes and emails output with differences to subscribers. Permits user accounts and registration. PHP/MYSQL.
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.
Simple C library for helping writting code with no memory leaks
Memory Profiler for C is a very simple C library for helping developers writting code which contains no memory leaks. It keeps track of all the allocated dynamic memory and allows for its printing. The source code is very simple and easily customizable.
