The Connection Broker adds desktops through a process called discovery, i.e., gathering available resources from external systems. The Connection Broker can discover:

• Microsoft® Windows® Terminal Services Servers and desktops using the Leostream Windows Agent
• Virtual desktops from the virtualization host or virtualization management system
• Physical machines registered in a Microsoft Active Directory® server

The external systems from which desktop are discovered are called centers.

This test auto-discovers all the centers on a Connection Broker, and reports the current status of each. Besides user-configured centers, the test also reports the status of an Uncategorized center; this center contains desktops running the Leostream Windows agents, which are not cataloged by another center. The Uncategorized center allows you to:

• Add physical machines without creating an Active Directory center
• Add a virtual machine that is not part of VitualCenter

The default parameters associated with this test are as follows:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, the host name of the server for which the test is to be configured has to be specified.

• In the PORT text box, specify the port number at which the host listens.

• By default, SSL flag is set to No, indicating that by default, the test connects to the Connection Broker via HTTP. If the Connection Broker is SSL-enabled, then set this flag to Yes.

• To enable the test to log into the Connection Broker and extract statistics of interest from it, specify the login name of a user in the USER textbox on the Connection Broker who is assigned the Administrator role. If need be, you can even create a special Administrator user on the Connection Broker for this purpose, and pass the credentials of that user to the test.

• Specify the password of the USER in the PASSWORD textbox.

• Confirm the PASSWORD by retyping it in the CONFIRM PASSWORD .

• In the TIMEOUT textbox specify the duration (in seconds) within which the test should timeout. The default duration is 30 seconds.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the Update button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
