Web Services for Licensing

Studio, Director, and the Licensing Administration PowerShell Snap-in use Web Services for Licensing to do the following:
  • Communicate with the License Server and manage users
  • Allocate and install licenses
  • Display License Server health, license usage, and other alert messages.
The Citrix Licensing Manager also uses it.

Citrix Licensing

The Citrix Licensing service is the Windows service responsible for core licensing functionality. Citrix Licensing services licenses to Citrix products and is responsible for managing the CITRIX vendor daemon, license server port 27000 (by default).

Citrix Licensing WMI

The WMI service provides access to Citrix Licensing WMI classes. There's a namespace (ROOT\\CitrixLicensing) with a few classes (notably, Citrix\_GT\_License\_Pool) that gives license usage and availability counts. Querying the License Server too often (more than every 15 minutes) might impact performance negatively.
