This tool allows the user to load, visualize and analyse Java thread dumps that are generated by Visual VM. Please see the Wiki for a Quick Start guide and tutorials.
JARep is a reporting tool for application performance data, extracted from a performance measuring tool like JAMon API. The data is then stored in a database. Via a webapp or a Swing application you can view the performance over time. See SVN source.
x4juli is an e(x)tension for(4) the (j)ava util(u) (l)ogging implemantion. It is a port of major log4j features (RollingFileHandler, PatternLayout, Filters). It includes a native implementation of "Jakarta Commons Logging" and "slf4j".
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.

Save on compute costs with Compute Engine. Reduce your batch jobs and workload bill 60-91% with Spot VMs. Compute Engine's committed use offers customers up to 70% savings through sustained use discounts. Plus, you get one free e2-micro VM monthly and $300 credit to start.
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
This project benchmarks the performance of three Java toolkits for working with VMware Infrastructure and vSphere: VI (vSphere) Java, the VI SDK for Java, and the vSphere SDK.
Tuning Fork Visualization Platform is a data visualization and analysis tool built on the Eclipse Rich Client Platform that supports the development and continuous monitoring of systems. It is particularly useful for real-time systems.

Watchdog is a Java performance monitoring and tuning framework. It is suitable for production environments allowing flexible auditing of performance data for later analysis by a comprehensive set of tools.
JHeap provides the toolset to help Java developers discover and fix the root cause of memory issues in their applications. JHeap integrates easily with your application server and has been designed to be used in production environments with low overhead.
A pretty primitive portable profiler for Java 5.0. It only produces "flat" profiles, has only experimental support for multithreaded code, and aims at minimal overhead.
log4j/log4net appenders and a supporting Eclipse RCP-based browser for viewing profiling information. The appenders operate either in-process or (to minimize overhead) remotely send their packets to a separate listener via UDP.
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.
Stat4j is a simple lightweight extension to the popular Java logging package log4. It allows logs to be intercepted and mined in real-time for application statistics including performance metrics.
jCello is a Java instrumentation framework which can be utilized to understand application behavior and performance. This package includes an agent (client) and collection/reporting server.
Performance Issue Detector: Based on Spring AOP, a set of interceptors which detects and reports slow API's, exact methods causing JDBC connection leaks and more.
