This project provides runtime performance monitoring and reporting for Java applications. It includes a simple API with timers and counters, data persistence, support classes and aspects (AspectJ & Spring AOP), and a reporting web application.
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.
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.
With up to 25k MAUs and unlimited Okta connections, our Free Plan lets you focus on what you do best—building great apps.

Yet Another JavaProfiler (YaJP) is a profiler tool that uses the JVMTI interface. It can be used to selectively trace a java program and store this information in a compressed logfile. This logfile can then later be analyzed using the same tool.
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.
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.
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.

'Sleepy' is a non-invasive profiler for the Windows platform that allows statistical profiling of applications through sampling the instruction pointer register. Sleepy presents results in a GUI built with wxWindows.
FProfiler is a JavaProfiler using log4j. Its very fast because it inserts the needed instructions into the byte-code of the class. It can be used to find "Hotspots" in Java programs, libs and servlet environments simply every Java class.
Free Java monitoring library to easily instrument apps to measure performance detail over time with minimal overhead. Has dashboard, SVG graphs. Extends Jamon and its statistical data, same usage. http://www.e-peas.com/opensla/. JMX, SNMP planned.
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.
