Citrix Virtual Desktops™ Delivery Controller service monitoring
In desktop virtualization, the NetScaler appliance can be used to load balance the Citrix Virtual Desktops Delivery Controller servers deployed by the Citrix Virtual Desktops environment. The NetScaler appliance provides a built-in monitor,
CITRIX-XD-DDC monitor, which monitors the Citrix Virtual Desktops Delivery Controller servers. In addition to the health check, you can also verify whether the probe is sent by a valid user of the Citrix Virtual Desktops Delivery Controller server.
The monitor sends a probe to the Citrix Virtual Desktops 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 Citrix Virtual Desktops 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 Citrix Virtual Desktops 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 Citrix Virtual Desktops servers, the
CITRIX-XD-DDC monitor is automatically created and bound to the Citrix Virtual Desktops Delivery Controller services.
