Agent > Collection Membership
Use this function to assign any machine ID to become a member of one or more collection. Collections are arbitrary groups of machines. Any machine can be made a member of any collection. Machines can also be members of more than one collection at the same time. Collections work together with group ID and machine ID filters to sort and list various machines. For example, you create a collection named servers and assign all your servers to be members of this collection. Then if you want to see all the servers in the accounting machine group, define a view that shows the servers collection and the accounting machine group.
