The Hosts console provides a hierarchical view of all currently defined hosts. Each host machine on which you have installed managers and agents must be added to the Framework Manager console through the Hosts console. Hosts are identified to the Framework Manager console by a unique agent name that is used to register the manager or agent after installation.
Hosts are added to domains, and domains allow you to organize your hosts into a tree structure. If Privileged User Manager is configured to manage 40, 100, or 400 hosts, the hierarchical structure allows for easy access to a particular host.
