Java Memory Profiler (JMP) uses the JVMPI interface to track objects and method times in the JVM (Java Virtual Machine). It uses a GTK+ interface to display statistics. The current instance count and the total amount of memory for each class is shown as is the total time spent in each method.
Spumoni provides an open framework for monitoring applications using SNMP. Specifically, it enables any program that can be queried via local commands to be health-checked by OpenNMS, Tivoli, OpenView, MRTG, RRDTool, and many others. This allows admins to employ enterprise-level monitoring capabilities for even non-SNMP-enabled applications.
XML Processing Benchmark for Java measures and compares the performance of XML Processing programs. It considers operations such as parsing, transformation, validation, encryption and decryption, custom access and manipulation, or any combination of these applied to one or more XML files or byte streams. It consists of code to carry out certain XML processing tasks, code and script to run the processing tasks and report performance measurements, and a framework to plug code and scripts in for processing. It also allows for XStat Processing, which collects certain statistics about an XML file.
OO Bench compares the speed of the same object-oriented tasks in several object-oriented languages. C++, Objective-C, and Java are currently supported. Support for Smalltalk, CLOS, CSharp, and Eiffel are in development. It aims to be simple, easy to understand, and easy to port. It also aims to follow the idioms and best practices advised by each language as much as possible. It is designed to make it easy to look up how a particular problem is best solved in another language.
XML Benchmark is a C/C++/Java XML parsers benchmarking toolset. Supported parsers include LibXML2, Xerces, Oracle XDK, Expat, RXP, QT, and Sun Crimson. Benchmarking fields include parsing (native, SAX, DOM), DOM manipulation, schema validation, XSL transformation, and XML signature and encryption.
TAU (Tuning and Analysis Utilities) is a set of tools for analyzing the performance of C, C++, Fortran and Java programs. It collects much more information than is available through prof or gprof, the standard Unix utilities, including per-process, per-thread, and per-host information, inclusive and exclusive function times, profiling groups that allow you to organize data collection, access to hardware counters on some systems, per-class and per-instance information, the ability to separate data for each template instantiation, start/stop timers for profiling arbitrary sections of code, and support for collection of statistics on user-defined events.
This small tool connects to the P6Spy JDBC logger and displays in real time the queries going to the database. It uses an integrated SQL parser to build statistics on the most accessed tables and columns to enable database index creation. Other information is also gathered and displayed, such as the request time for a single request, for a class of request, and for all the requests. Sorting may be done on these views to detect database problems efficiently.
RUBiS is an auction site modeled after eBay.com used to benchmark e-commerce Web site technologies. It is currently used to evaluate design patterns, application servers, and communication layers scalability. Several implementations using PHP, Servlets, Enterprise JavaBeans (EB BMP, EB CMP, MDB, SB, EJB 2.0 CMP, Session Façade, etc.) are already available and new versions for JDO and .Net are currently developed.
The Java Application Monitor (JAMon) is a free, simple, high performance, thread safe, Java API that allows developers to easily monitor production applications. JAMon can be used to determine application performance bottlenecks, user/application interactions, and application scalability. JAMon gathers summary statistics such as hits, execution times (total, average, minimum, maximum, standard deviation), and simultaneous application requests. JAMon statistics are displayed in the sortable JAMon report.
DJFractal is yet another fractal generator which distributes fractal data to multiple computers. Fractal data are created locally and distributed to other computers that run the appropriate fractal-generation software, which may be hosted on workstations, or on a Java enabled Web-browser through applets, or on a system with JavaCard. DJFractal's unique feature is the "smart" algorithm it uses to compute (and draw) the most interesting part of a fractal first.
