Floating license

Unlike per-seat license which counts installed profiler copies, floating license counts the running profiler instances. Floating license allows to install as many copies as you wish, but the number of concurrent users (copies running at at time) may not exceed the number of purchased licenses.

Floating licenses are managed by the license server. By default YourKit offers cloud based license server, which requires zero configuration and maintenance costs. There is also an option to host the license server on-premise in your local network.

The license server supports two operation modes:

  • Automatic license management: The default mode when a license is allocated when a user starts the profiler client, and is automatically released when the client exits. In case of an abnormal client termination or network connectivity problems the license is released automatically after a certain time period and will become available to other users.

    The automatic mode requires a network connection to the license server while working with the profiler client.

  • Locked license: a user may explicitly lock a license to his/her machine. The license will not be available to other users until the owner or the license administrator explicitly unlocks it.

    While the license is locked, a network connection to the license server is not required to work with the profiler client.

If you have several floating licenses, you may lock only some of them, on demand, e.g. when your team member has to work in a restricted network environment while traveling or at a customer site, while allowing the automatic management for others.
