Controller Details Test

Controllers are server machines running instances of the broker service. The broker service is responsible for the brokering of user sessions to desktops or applications, and for power management of the underlying machines. An operational site must contain at least one Controller.

This test auto-discovers the Desktop Delivery Controllers configured within a site, and reports the current status of each controller and the count of machines registered with every controller. The test also reveals the current status of the licensing server on each controller. This helps administrators to re-allocate additional set of licenses on the Citrix License server and restart licensing services if the state of the licensing server was either not connected or failed or was found to be incompatible.

Target of the test : A Citrix Delivery Controller 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 this test is to be configured.
Port	Refers to the port at which the specified host listens to.
Username	In order to monitor the target Delivery Controller 7, eG requires a special user with the following privileges; The All scope and read-only privileges The Allow log on locally security privilege on the Delivery Controller host The steps for assigning such privileges to a user are discussed in the Pre-requisites for monitoring the Citrix Delivery Controller 7.x.

Confirm Password	Confirm the Password by retyping it here.
Domain	Here, specify the domain to which the user specified in the Username text box belongs 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

Controller state

Indicates the current state of this desktop delivery controller (broker).

Number

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

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

Licensing server state on this controller

Indicates the current state of the licensing server on this desktop delivery controller (broker).

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

State	Numeric Value
Ok	1
License Expired	2
Not Connected	3
Server Not Specified	4
License Not Installed	5
Incompatible	6
Failed	7

Note:

By default, this measure reports the above-mentioned States while indicating the current state of the licensing server on a broker. However, the graph of this measure will represent states using the corresponding numeric equivalents – i.e., 1 to 7.

Total registered machines

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

Number

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