Domain Controller Time Check Test

Citrix Delivery Controller 5.x will not be able to launch VMs that are in an unregistered state. The virtual desktop agent executing on a VM might be unable to register the desktop with the DDC (hence, the unregistered state) owing to many reasons; the most important of them is the lack of time synchronization between the DDC and the Active Directory server it integrates with for authenticating user logins.

If virtual desktops are found to be in an unregistered state, you can use this test to check whether the DDC time-syncs with the AD server. If this test reports an error in time synchronization, then, you can easily conclude that this is the cause for the unregistered state of the virtual desktops

Target of the test : A Citrix Delivery Controller 5.x

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the domain name of the AD server with which the Citrix Delivery Controller 5.x integrates.

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 this test is to be configured.
Port	Refers to the port at which the specified host listens to.
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.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Domain time synchronization status	Indicates whether the DDC time syncs with the domain controller.		This measure reports the value Ok if the DDC time-syncs with the AD server. The value Error, on the other hand, is reported if the DDC time does not sync with the AD server’s time stamp. The numeric values that correspond to the above-mentioned states are as follows: State Numeric Value Ok 1 Error 0 Note: By default, this measure reports the above-mentioned states while indicating the time sync status of the DDC with the domain controller. However, the graph of this measure will represent states using the corresponding numeric equivalents only – i.e., 0and 1. If this measure reports the value Error, then, you can use the detailed diagnosis of this measure to know the time stamp of the AD server when the problem occurred.

If this measure reports the value Error, then, you can use the detailed diagnosis of this measure to know the time stamp of the AD server when the problem occurred.
