Connection Broker Centers Test

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 Agent
  • Virtual Desktops from the virtualization host or virtualization management system
  • Physical machines registered in a Microsoft Active Directory server
  • Applications hosted by a Citrix XenApp 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 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 part of a non-natively supported hypervisor, such as Microsoft Hyper-Vi

Target of the test : A Leostream Connection Broker

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each of the Connection Broker centers being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.


Specify the IP address of the Connection Broker for which the test is to be configured.


Refers to the port used by the Connection Broker is listening. 


By default, this 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 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. Refer to Pre-requisites for Monitoring the Leostream Connection Broker to know how to create such a user.


Specify the password of the user here.

Confirm Password

Confirm the password by retyping it here.


Specify the duration (in seconds) within which the test should timeout. The default duration is 30 seconds.

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

Status of the CB Center

Indicates the current status of the center.


The status indicators and what they represent are discussed below:

Numeric Value Status Description
1 Online Indicates the center is operating normally
2 Offline Indicates that the Connection Broker is unable to contact the center
3 Needs Upgrade Indicates that the Leostream Agent in this center needs to be upgraded. This setting applies only for centers that use the Leostream Agent.
4 Disk Full Indicates that the center’s disk is full
5 Refreshing Indicates that the Connection Broker is refreshing the contents of this center


This measure reports the States listed in the table above to indicate the status of the CB center. However, in the graph of this measure, the mode of the routing engine is indicated using only the Numeric Values listed in the above table.

Is CB center active?

Indicates whether the center is active or inactive currently.


This is a user-configured value.  If the measure reports the value 1, it indicates that a user created a center, then wanted to have the Broker ignore the contents of the center, without deleting the center from the Broker.

The value 0 indicates that the center is inactive.
