(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.
The DaCapo benchmark suite is designed to faciliate performance analysis of Java Virtual Machines, compilers and memory management. It comprises a harness and a suite of open source real-world programs.
A very simple implementation of C++ keyword sizeof for Java 5+. Developers can use it to know the real size of objects in memory.
Profiler4j is a simple-to-use CPU profiler for Java that supports remote profiling and on-the-fly configuration.
This is sister project for osDQ which provide Restful APIs
(Beta Version) This is sister project for https://sourceforge.net/projects/dataquality/ . It provides Restful APIs for features for data quality and data preparation features. This project will help projects which want embed data quality and data preparation features in their project or UI using restful calls. Data Cleansing APIs
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.
osDQ project dedicated to create apache spark based data quality
This is an offshoot project of open source data quality (osDQ) project https://sourceforge.net/projects/dataquality/ This sub project will create apache spark based data quality and data preparation features for big data. This uses java API of apache spark
The Duine Framework allows one to develop prediction engines for recommender systems. It contains a set of prediction techniques, a way to combine these techniques and a profile manager. The framework has a plug-in architecture, allowing customization.
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.
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.
log4js has moved to Github: http://stritti.github.io/log4js.
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 ;-)
Performance Monitoring Tool for Java / J2EE Applications. Features: light-weight profiler, AOP based, lists API times, JDBC / SQL statistics, central logging, cluster support, web UI, call trees, configurable monitoring levels.
JDBC Tools is a proxy driver framework for monitoring Java database access. It has pre-built JDBC logger and SQL query planning modules, but can be extended through a simple API to perform other monitoring operations.
A fully automated database benchmark suite that prints tabular and graphic results for multiple tested disciplines, given JDBC database connections. Some free open source database engines are included.
JISC Demonstrator (eTools) project that integrates both the JISC DELTA and eProfile toolkits into a single user-interface. Users can view and search their social-networks (based on the eProfile functionality), and search for resources in Delta.
Beet adds user behavior and performance tracking to a Spring-based Java app. HTTP requests, method calls, and SQL statements are tracked and associated to user and session. includes XML, binary XML, and JDBC loggers. See http://beet.sourceforge.net.
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.
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.
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.
Eclipse based framework to create interoperability among UML2 and Architectural Description Languages (ADLs). DUALLy works at two abstraction levels: meta-modeling (via AMW weaving models), and modeling (via UML, Ecore models and ATL transformations).
Graal collects profiling information when interpreting Java Bytecode. This tool gives the user the ability to inspect these Graal internal datastructures easily. Installation instructions are provided in the wiki.
JBoss Profiler Tomcat Portion is a tool to port JBoss Profiler from JBoss to Tomcat. It can control the start, pause and stop operations on logging Tomcat runtime data into file system by web interface or third-party tool as JConsole.
JDLabStudio is a graphical front-end for the Java Debugging Lab Agent (JDLabAgent). JDLabStudio scans java packages, displays class files and generates JDLabAgent config files. JDLabAgent-traces are used for reconstructing control and data flows.
