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 exception extractor. This utility will parse all files (either plain text or bzipped) and tries to search for various exceptions. It then tries to match exceptions against grouping rules (regexps). It is also able to group unrecognised exceptions.
Java agent which recognizes "flows" as unique sequences of instrumented method calls. Runtime statistics are collected for the dynamically detected flows during snapshot interval. The instrumented methods may be set either manually via UI or automatically in drill down mode. The automatic drill down mode effectively instruments classes generated by frameworks like Hibernate, Rhino, etc.
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.
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.
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.
This project is designed to help programmers understand the resource utilization of their code in the Java Virtual Machine and provide real time feedback via a GUI interface.
The Java CCTAgent is a JVMTI agent that collects calling context tree information from a running Java program.
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
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.
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.
Software Monitoring Framework
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.
LEDRack is a very simple and flexible framework app for monitoring and administering production applications through JMX-based Plugins.
Count lines of code, including comment and blank lines. Interactive GUI, or command line. End user may add new file types by editing config file. Supports any source language that uses characters to delimit comments, such as // or /* */.
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.
Profiler for Oracle extended SQL trace files
LightProfiler – application for performance analysis of the Oracle databases. It generates detailed resource profile for extended SQL trace files (10046 event), containing information about consuming of response time (by events, by cursors, etc.), data files usage, error analysis (SQL, PL/SQL) and much more. Also it contain tools for additional processing of trace files (extract session data, splitting files) and for management of database's sessions (disconnecting, tracing, monitor parameters, blocking locks, events and etc.)
A lightweight java monitoring api for intrusive monitoring
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.
