Memory and CPU Profiler
Used to find memory leaks, inefficient temporary-storage issues, CPU bottlenecks, and unit test performance regressions. Use the Profiler to test and improve the performance of Java applications, applets, servlets, JavaBeans, Enterprise JavaBeans (EJBs) and JavaServer Pages (JSPs). The Memory Profiler provides real-time display of all classes used by the test program and the number of allocated instances. The CPU Profiler displays test results for each thread or thread group for pure CPU use or for elapsed time (pure CPU and inactive phases).
Provides a real-time display of the progress of all threads running within the Java Virtual Machine (JVM), the ability to monitor wait-states and locks, and even predict potential deadlock conditions in the code.
Profiles the performance behavior of Java EE application code across common Java EE components such as JDBC, RMI, JSP, JNDI, Enterprise JavaBeans (EJBs), JMS, and Web service protocol containers.
Code Coverage allows you to determine the exact lines of source code that are being executed. In real time, you can view how frequently each class, method, and line of code is executed. Code Coverage lets you test applications, applets, servlets, JavaBeans, Enterprise JavaBeans (EJBs), JavaServer Pages (JSPs), and virtually any other Java code. With Code Coverage, you can easily spot and remove dead code from applications, improving quality and reducing the footprint of an application.
J Optimizer Agent
The J Optimizer Agent is a profiling agent that works with either of two standard profiling interfaces that a JVM might support: Java Virtual Machine Profiler Interface (JVMPI) or Java Virtual Machine Tool Interface (JVMTI).
Code Audits and Metrics
The audits and metrics capabilities in J Optimizer can be used to solve the code quality, code review and code dependency issues typically faced in software development. J Optimizer¿s audits and metrics are designed to aid developers in finding and fixing problems in their code earlier in the development process. J Optimizer¿s audits perform a static analysis of your source code, identifying coding problems like potential race conditions, unchecked exceptions and more. J Optimizer¿s metrics provide a similar analysis for design problems in your project.
Enables developers to continuously monitor and measure the impact of performance changes by allowing them to compare visual snapshots of their progress. It allows for analyzing snapshots so users can compare profiler, code coverage, and request analyzer snapshots. It also generates reports that can be exported in PDF and HTML format.
Snapshots are binary files that capture all the data from a particular test run. Snapshots can be opened for analysis in the product that generated it, such as Profiler, Code Coverage, or Request Analyzer.
Touch-point Install Option
Users have the option to install J Optimizer touch point plug-in into an existing Eclipse or Eclipse-based product and make it profile ready.
J Optimizer supports profiling of Java applications running on today¿s most popular commercial and open source application servers including BEA WebLogic Application Server, IBM WebSphere, JBoss, Oracle Application Server, Apache Geronimo, Apache Tomcat, and Sun GlassFish.
