PureAgent monitors response times from an agent to a server by replaying transactions at specified intervals. This includes static and dynamic Web applications as well as other server applications. Response times are collected and alarms can be sent if performance and availability goals are not fulfilled. The agent is managed using a standard Web browser. Using the browser, an administrator specifies transactions to run, intervals, alarm settings, etc.
GCViewer is a Swing-based application that visualizes the verbose garbage collection output generated by the IBM, Sun, HP and BEA Java VMs (-verbose:gc/-Xloggc:-flags). The data can also be exported as CSV for forther processing with a spreadsheet application. Visualizing the data can help when one is tuning the garbage collector, especially the generation sizes and initial heap size.
PushToTest TestMaker is a distributed test automation platform for application performance management and monitoring. It repurposes tests written in Selenium, soapUI, TestGen4Web, and Mozmill, and unit tests in Java, .NET, Jython, Groovy, PHP, Ruby, and Perl into functional tests, load and performance tests, and business service monitors. TestMaker is ideal for Web applications, Service Oriented Architecture (SOA) applications, Rich Internet Application (RIA using Ajax, Flex, Flash) and Business Process Management (BPM) applications.
miniLogger is a very small (4 classes and a 10KB jar) and easy to use logger. It uses a logging API that is a subset of JDK 1.4 logging but works on all Java 2 versions. It has been tested on Windows, Solaris, IRIX, and Linux for versions 1.2 and 1.3 of the Sun JDK. It supports logger control from the command line. Logger names are hierarchical separated by dots, and selecting any name automatically selects all names below. If logger_name is an empty string, it will affect all loggers. The loggers and level options are evaluated from left to right. It prints the thread name, source file name, and number line by default, and output can be redirected from System.err to file or any PrintStream. Finally, the logger hierarchy can easily mirror a package/class hierarchy or can be arbitrarily defined by the user.
