USE IN VIRTUAL ENVIRONMENT
If the profiler is installed in a virtual environment such as a container or a full virtual machine, and such virtual environment allows for multiple instantiations (running copies), the profiler must be activated with a floating license, and the floating license activation must not be locked, so that each time the profiler runs it must obtain a license from the license server. You may not use any other license flavor e.g. a seat license or lock a floating license in such environment.
A seat license can be used instead of the floating license to activate the profiler in a virtual machine only if there exists only one copy of the machine per licensed seat. You may make a copy of the machine for archival purposes, but you may not clone the machine and/or run multiple instances of it.
SPECIAL CONDITIONS FOR USING THE COMMAND LINE TOOL
A part of the Software is the command line tool to control profiling without using the graphical user interface. The tool is accessible via the scripts YourKitTools.bat on Windows and YourKitTools.sh on Linux.
You may install any number of copies of the Software for the purpose of using the command line tool. To use the command line tool, a copy does not need to be activated with a license key.
