(Java 5 and newer / JVMTI only) Don't instrument bytecode with instructions needed for CPU tracing. (Java 5 and newer / JVMTI only) Don't instrument bytecode with instructions needed for object allocation recording. serverctl and you get a list of all available options. To get a complete list of the available options, type. Setting the above described env variables is still mandatory, but setting the additional JVM option is not: 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. With its detailed memory and CPU profiling, code hotspot detection, and easy-to-use interface, developers can quickly identify and eliminate performance bottlenecks in their applications, making them faster and more efficient.To be able to profile a Java application, it is necessary to provide the YourKit tool an interface to the Java application. It is a powerful tool that helps developers optimize the performance of their Java applications. ![]() ![]() Q: Can I use it to profile other languages besides Java?Ī: No, It is designed explicitly for profiling Java applications. Technical Details and System Requirements Easy-to-use interface: The tool has an easy-to-use interface that makes it easy for developers to navigate and understand the performance data.This helps developers identify and eliminate synchronization issues that can lead to poor performance. Threads and monitors: The software for Windows provides detailed information on the threads and monitors in your Java applications.This helps developers focus their optimization efforts on the areas of the code that are causing the most performance issues. Code hotspots: The tool automatically detects code hotspots, which are the areas of the code that are executed most frequently.This helps developers identify and eliminate memory leaks and reduce CPU usage. Memory and CPU profiling: The software provides detailed information on how your Java applications use memory and CPU resources.This powerful tool helps developers to identify and eliminate performance bottlenecks in their Java applications, making them faster and more efficient. However, with the increasing complexity of Java applications, it becomes challenging to optimize their performance. Java is a popular programming language widely used to develop applications across various platforms. Optimize the performance of your Java applications. ![]() Free Download YourKit Java Profiler full version standalone offline installer for Windows.
