In desktop virtualization, the Citrix ADC appliance can be used to load balance the Web Interface (WI) servers and the XenDesktop Delivery Controller servers deployed by the Citrix XenDesktop environment. The Citrix ADC appliance provides a built-in monitor, CITRIX-XD-DDC monitor, which monitors the XenDesktop Delivery Controller servers. In addition to the health check, you can also verify whether the probe is sent by a valid user of the XenDesktop Delivery Controller server.

The monitor sends a probe to the XenDesktop Delivery Controller server in the form of an XML message. If the server responds to the probe with the identity of the server farm, the probe is considered to be successful and the server’s status is marked as UP. If the HTTP response does not have a success code or the identity of the server farm is not present in the response, the probe is considered to be a failure and the server’s status is marked as DOWN.

The Validate Credentials option determines the probe to be sent by the monitor to the XenDesktop Delivery Controller server, that is, whether to request only the server name or to also validate the login credentials.

Note: Regardless of whether the user credentials (user name, password, and domain) are specified on the CITRIX-XD-DDC monitor, the XenDesktop Delivery Controller server validates the user credentials only if the option to validate credentials is enabled on the monitor.

If you use the wizard for configuring the load balancing of the XenDesktop servers, the CITRIX-XD-DDC monitor is automatically created and bound to the XenDesktop Delivery Controller services.

To add an XD-DDC monitor with the validate credentials option by using the command line interface

At the command prompt, type the following commands to add an XD-DDC monitor and verify the configuration:

add lb monitor <monitorName> <monitorType> -userName <userName> -password <password> -domain <domain_name> -validateCred YES

show lb monitor <monitorName>
<!--NeedCopy-->

Example:

 > add lb monitor xdddcmon Citrix-xd-ddc -userName Administrator -password E12Dc35450a1 -domain dhop -validateCred YES
 Done
> show lb monitor xdddcmon
