The Machine Agent can register to the controller in 2 ways:
1. Machine Agent with Basic enabled (sim-enabled = False)
For this configuration, you have 2 choices
1.a. Let the Machine Agent create a dummy application. The Machine Agent can create a dummy application by passing the below flags in <MA-Home>/conf/controller-info.xml
<application-name>NameOfApp</application-name>
<tier-name>NameOfTier</tier-name>
<node-name>NameOfNode</node-name>
This will create a dummy application for you on the controller.

1.b. Install a Machine Agent with the same <unique-host-id> as an Application agent (Java agent). This will correlate and have the Machine Agent report under the Application Tab.
A screenshot is attached for both options.
2. Machine Agent with sim-enabled set to true.
With this setting, the Machine Agent will report under the Servers Tab (Top view)
The metrics difference between Basic and Server Visibility are noted here:
