Controllers Test

Controllers are server machines running instances of the broker service. This test auto-discovers the delivery controllers configured within a site, and reports the current status of each controller and the count of machines registered with every controller.

Target of the test : A controller in a Citrix Virtual Apps/Desktops Site 7.x

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the XenDesktop server site to which the target controller belongs.

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 Pre-requisites for monitoring the Citrix Virtual Apps/Desktops Site 7.x topic.
Confirm Password	Confirm the Password by retyping it here.
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

Description

Measurement Unit

Interpretation

Controller state

Indicates the current state of this desktop delivery controller.

Number

This test reports one of the following values to indicate the current state of a desktop delivery controller:

Active – Indicates that the controller is powered-on and fully operational
On – Indicates that the controller is powered-on, but not fully operational
Failed – Indicates that the controller has failed due to some reason
Off – Indicates that the controller is powered-off

The numeric values that correspond to the above-mentioned states are as follows:

State	Numeric Value
Active	1
On	2
Failed	3
Off	4

Note:

By default, this measure reports the above-mentioned States while indicating the current state of a controller. However, the graph of this measure will represent states using the corresponding numeric equivalents – i.e., 1 to 4.

The detailed diagnosis of this measure reveals when the controller was last accessed, when it was last started, the zone to which the controller belongs, and also displays the site services that were active on the controller during its last access.

Total registered machines

Indicates the number of machines that are currently registered with this controller.

Number

The detailed diagnosis of the Controller state measure reveals when the controller was last accessed, when it was last started, the zone to which the controller belongs, and also displays the name of the machine on which the controller is installed, the version of the controller, the Operating system of the machine and the Operating system version.
