![]() It includes the option to start the JVM with the YourKit agent library. Hint: In CQ 4.2, the serverctl script has become more advanced, allowing for providing various options on startup. Profiler agent is listening on port 10001. *** HINT ***: Use Java 5 (or newer) when possible! The agent library prints some information to the standard output (in case of CQ it is server(logs/startup.log): Now you're ready to start your application and the actual profiling. Now it is a matter of telling the JVM to actually integrate this library, which differs according to the JVM version in use: Java Version This setting makes the agent library available to the JVM. #- # enables the YourKit Java Profiler #- YJP_HOME="/home/honwai/yjp-6.0.16/bin/linux-x86-32" export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$YJP_HOME Include setting environment variables in the start-script of your application.įor example, in a CQ start script under Linux, do the following: First, enable profiling by providing the path to the respective OS agent library where the JVM is running on (see Enabling Profiling). You integrate the YourKit agent library into the JVM where the target application you want to profile is running. When it comes to profiling applications, YourKit Java Profiler will meet all your expectations and it will make your work easier at the same time.To be able to profile a Java application, it is necessary to provide the YourKit tool an interface to the Java application. The information is presented neatly and it is made easy to understand by interactive graphs and charts. The presented information includes, but is not limited to CPU and memory usage telemetry, stack traces and CPU usage estimations. Its welcome screen also contains a series of links to online documentation materials, as well as an option for loading a demo application, so you can see how the program works.Īfter targeting and monitoring an application, Java Profiler will provide you with a vast range of results, on a different page, where they are categorized on tabs. Although it features numerous menus and options, the software is designed to be easy to use. Additionally, you can integrate Java Profiler with an IDE or with a standalone Jave EE Server. When you launch the program, its user interface will greet you with a welcome screen, on which you can import local applications to monitor them or start monitoring remote applications. ![]() Regardless of your preferred platform, downloading and installing YourKit Java Profiler shouldn't take more than a minute. Since it is a Java-based application, YourKit Java Profiler can be used on various operating systems, like Windows, Mac OS X, Linux, Solaris and others. The software is free to try, without any kind of functionality restrictions and you can even request a trial extension if you are not done evaluating. The software lets you run profiling tasks on multiple machines, locally or remotely and it offers full overhead control. It offers a wide range of powerful features, which allow you to profile any kind of SE or EE applications, servers and frameworks, at their development and production stages. YourKit Java Profiler makes CPU and memory profiling straightforward and easy.
