To install YourKit Java Profiler on Ubuntu, follow these steps based on the information available from the YourKit website:

  1. Download the Profiler:
    • Visit the YourKit Java Profiler download page at https://www.yourkit.com/java/profiler/download/.
    • Select the Linux version of YourKit Java Profiler 2025.3, which supports Java 8 to Java 24 and is compatible with Linux (including Ubuntu) on architectures like arm32, arm64, ppc64le, x64, and x86. Ensure your system meets the system requirements for compatibility.
  2. Download the Archive:
    • Download the .zip archive for Linux (e.g., YourKit-JavaProfiler-2025.3-<build>.zip). The download link is available on the YourKit download page.
  3. Unzip the Archive:
    • Open a terminal and navigate to the directory where the downloaded file is located (e.g., ~/Downloads).
    • Unzip the archive using the following command: 
      unzip YourKit-JavaProfiler-2025.3-<build>.zip -d /opt/yourkit

      Replace <build> with the actual build number from the downloaded file. This command extracts the profiler to /opt/yourkit. You can choose another directory if preferred.

  4. Run the Profiler:
    • Navigate to the extracted directory: 
      cd /opt/yourkit
    • Run the profiler using the provided script: 
      ./bin/profiler.sh

      This launches the YourKit Java Profiler user interface.

  5. Optional: Unattended Installation with License Key:
    • If you have a license key and want to automate the installation, you can use command-line options to accept the EULA and apply the license key. For example: 
      ./bin/profiler.sh -accept-eula -license-key=<key>

      Replace <key> with your actual license key. This is useful for automation or scripted setups.

  6. Integrate with Development Environment (Optional):
    • If you use an IDE like Eclipse, IntelliJ IDEA, or NetBeans, YourKit provides plugins for seamless integration. For Eclipse, for example:
      • Open Eclipse and go to Help > Install New Software.
      • Add the YourKit plugin repository: https://www.yourkit.com/download/yjp2025_3_for_eclipse/.
      • Select the YourKit Java Profiler plugin, follow the installation prompts, and restart Eclipse if required.
      • Alternatively, use the offline archive at <Profiler Installation Directory>/lib/eclipse-plugin/yjp2025_3_for_eclipse.zip.
    • After installation, the “Profile” action will appear in Eclipse’s toolbar, main menu, or context menus for easy profiling.
  7. Verify Installation:
    • Once the profiler is running, the welcome screen will allow you to monitor locally running Java applications, connect to remote applications, or open existing snapshots. You can also load a demo application to explore the profiler’s features.
  8. Additional Notes:
    • If you encounter issues, ensure Java (version 8 or higher) is installed on your system, as YourKit Java Profiler requires a compatible JVM. You can check your Java version with: 
      java -version
    • For remote profiling, ensure SSH access is configured if profiling applications on remote servers.
    • YourKit offers a 15-day free trial, so no license key is required initially. For non-commercial open-source projects, you can contact YourKit sales for a free license.
    • If the profiler fails to start (e.g., due to spaces in the installation directory), move the extracted folder to a path without spaces, such as /opt/yourkit.

For further assistance, refer to the YourKit documentation or contact their support via the YourKit website.
