Monitoring and metering licenses
Licenses can be checked out to a user, device, session, server or appliance, depending on the licensing model for each product. Learn more about licensing models by product.
All licenses are contained in a pool on the license server(s). License check-out is triggered based on product-specific system activity.
- A user tries to access a virtual application
- A device connects to a desktop
- A virtual server host machine is added to a server pool
- An appliance is enabled on the network
When an activity begins, the product requests a license from the License Server. If the appropriate license is available, the License Server checks it out and associates it accordingly.
In the event a product loses communication with the License Server, the product will continue to function for a predetermined license grace period. As an additional precaution, Citrix also recommends that customers back up licenses and the license server.
