Running the profiler

Please follow instructions for your operating system on how to launch the profiler UI:

Windows

Launch YourKit Java Profiler from in the Start menu

Mac OS X

Download the application, unzip; optionally, move to /Applications.

Troubleshooting: what to do if the profiler crashes on startup

Try to avoid using the native application launcher by running the following command the Terminal:

<profiler installation directory>/Contents/Resources/bin/yjp.sh

Although the profiler started this way will have minor UI defects such as non-native main menu style and an incorrect application icon in the dock, in general it will work just fine.

Note: since build 14112 the profiler falls back to this approach automatically, i.e. tries to restart itself via yjp.sh after a crash.

Linux, Solaris, AIX, HP-UX, FreeBSD

Unpack the installation bundle and run <Profiler Installation Directory>/bin/yjp.sh

The profiler UI requires Java 8 to run. The download bundle contains JRE for Linux x64 and should run out of the box on that platform. On other platforms, please ensure that the appropriate Java version is installed.
