1) Specify the host name and port (ManagementServerHost and 8080) of the Management Server to which need this concentrator to connect in the Configure Server URLs step.
2) Ensure that the instance is shut down and configure it as a concentrator by editing its fglam.config.xml file so that it listens for connections from downstream instances on a specified port (8081).
3) Restarting the Agent Manager instance on IntermediateHost. This instance is now configured as a concentrator: it listens for connections from downstream instances on port 8081 and forwards data to the Management Server on port 8080.
The concentrator is set up on IntermediateHost, configure the Agent Manager instances on the monitored hosts to connect to the concentrator:
1) Stop Agent Manager instances,
2) Run the Agent Manager configuration interface for each instance.
3) Specify the concentrator’s host name and the port on which it is listening (IntermediateHost and 8081) when setting the URL to which the instances connect.
4) Restart Agent Manager.
-- How to configure the concentrator to listen for connections from downstream instances--
To create a secure connection between the concentrator and downstream Agent Manager instances using HTTPS. follow the instructions in Creating a Secure Connection with Downstream Instances.
1. Open the /state//config/fglam.config.xml file for editing.
2. Locate the XML element.
3. Add an child element:
After add an child element:
a) Replace port_number with an available port number. This is the port on which the concentrator listens for connections from downstream Agent Manager instances.
b) Optional. If required, can also bind the concentrator to single network address. To do so, include the attribute address="network_address" in the http-downstream child element (shown as an optional attribute in Step 3), replacing network_address with the network address where the concentrator to receive connections from the downstream instances.
3. The optional address attribute is useful when a machine has two or more network addresses, and the connections to the Management Server to go out from one, and the connections from the downstream instances to come in to another.
4. Configure the concentrator to listen for connections on multiple different ports by adding additional elements and setting the port number (and, optionally, the network address), as described above.
This is useful in situations where the concentrator machine has multiple network connections, and require the concentrator to listen on different network connections with different ports. For example, the concentrator listens on network connection 1 with port 8081 and listens on network connection 2 with port 8082.
5. Restart the concentrator.
