Using CERMM

Groups and tags

A machine is several things at once, so CERMM has tags and rule groups instead of a folder tree.

Tags

A tag is a label on machines: homelab, client:acme. Lower case. Set them from a device's menu → Tags…, or its nameplate. Rename or remove a tag everywhere at once on Devices → Groups.

Groups

A group is a saved rule. It can match tags, role (server or workstation), kind, system, and name or IP text; all of them must match. A new machine joins the moment it enrolls.

Using them

• Groups are pills in the Devices list. The filter box matches #tag.
• The run dialogs (patches, scripts, software, playbooks) have Select a group or tag.
• Schedules can aim at a group or tag: whoever is in it when the schedule fires. A group a schedule uses can't be deleted.

Every change is in the audit log. Clients and sites come with the MSP edition.
