Citrix: VM Controller

Distribution Official part of Checkmk
License GPLv2
Supported Agents Windows
This checks displays the controller to which a VM is currently associated. It is purely informative and always OK. The citrix_farm.ps1 plugin must be installed on the controller, and the Checkmk agent must be executed with Citrix Admin permissions for this to work. Data for the hosts is collected on the controller and given to the monitoring server as piggyback data.

Discovery

One service is created for each controller.
