Each host view contains a default group called Holding Area, and all newly connected hosts are placed there. You can create your own set of host groups inside each host view to categorise the hosts in a relevant way.
The Host Groups are managed on the Manage groups page. The page shows the existing Host Views as tabs, and you can create Host Groups for each Host View.
All managed hosts are included in each Host View, either in the Holding Area or assigned into a specified Host Group. To add more detailed grouping of the hosts, you can create several levels of Host Groups.
To create a new host group:
Click Hosts → Manage groups on the menu.
On the Manage groups page, select a Host View by clicking its tab.
Click the topmost Add subgroup button to add a new group to the view. Enter a name for the new group and click Save.
After you have created some groups, you can also add new subgroups under existing groups by clicking the Add subgroup button next to the group's name.
You can move subgroups to another Host Group under the same Host View. To move a host group, click the Move button next to the group you wish to move, and select a new parent group for the group from the drop-down list and click Save.
You can rename or delete a host groups by clicking the Rename or Delete button next to that group or subgroup.
Note that a host group cannot be removed if other objects of the system refer to it.
For detailed instructions on managing the host groups, see Managing Host Groups.
