Open Fleet and keep the view on list, grouped by group. Needs attention is open: Accounts server is there because the disk is at 92%. Onboarding is open: Spare laptop has no group yet. The site and role headings start closed, so Melbourne, Branch and the roles are not in the list. The link on the bar says expand all.
Press expand all. Site opens: Melbourne holds Accounts server, files01, Lab host and Reception PC, and Branch holds Branch router. Role opens too: DC is Accounts server, hypervisor is Lab host. The link now says collapse all. Press that and the site and role headings close again. Needs attention and Onboarding stay as they were. Click one heading when you only want that group.
