Controller Services Test

The broker service is responsible for the brokering of user sessions to desktops or applications, and for power management of the underlying machines. Every controller in a site runs an instance of the broker service. In addition to the broker service, the following critical services also run on a controller:

  • AD identity service
  • Configuration service
  • Host service
  • Machine creation service
  • Admin service
  • Monitoring service
  • Logging service

This test periodically checks the health of each of these services on the target controller in a XenDesktop site, and reports abnormalities (if any). With the help of this test, you can promptly detect which services have failed.

Target of the test : A controller in a Citrix XA/XD Site 7.x

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every controller configured within a site.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed

Host

The IP address of the host for which the test is being configured.

Port

The port number at which the specified Host listens to. By default, this is 80.

Domain, Username
and Password

To connect to a delivery controller in a site and pull out metrics from it, the eG agent requires Farm Administrator rights. In order to configure the eG agent with Farm Administrator privileges, specify the Domain to which the target controller belongs and enter the credentials of a user who has the Farm Administrator rights in the Username and Password text boxes. This user should also be assigned the Allow log on locally privilege on the Citrix XA/XD Site 7.x host. The steps for assigning the Allow log on locally privilege are explained in the Monitoring the Citrix XA/XD Site 7.x topic.

Confirm Password

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Machine creation service status

Indicates the current status of the Machine Creation Service on this controller.

 

The Citrix Machine Creation Service creates new virtual machines.

Once a valid user logs into the Citrix Delivery Controllervia the Web Interface, the controller manages the delivery groups by building, starting, and shutting down the desktops as required. At this juncture, the controller relies on Machine Creation Services (MCS) to deliver the appropriate desktop image to the Pooled and Dedicated delivery groups.
