+ A surveillance category is a named grouping of nodes used across + OpenNMS for filtering, dashboards, notifications, and the surveillance + view. A node can belong to any number of categories, and group + authorizations can restrict which categories a user group sees. +
+
+ Add New Category creates a category with an optional
+ description; Edit changes the description (the name is
+ the identifier and cannot be changed). Manage Nodes
+ assigns and unassigns nodes. Delete removes the
+ category — filters or authorizations that reference it by name stop
+ matching, so review them afterward. The same operations are available
+ to tooling through the /rest/categories REST API.
+
+ Are you sure you want to delete the surveillance category + {{ categoryToDelete?.name }}? Nodes will lose this + category, and any group authorizations or filters that reference it by + name will no longer match. This action cannot be undone. +
+ ++ Search the node inventory and toggle each node in or out of this category. + Changes are applied immediately against the category membership API. +
+ ++ Nodes marked (requisitioned) are managed by a requisition — category + changes on them are overwritten on the next provisioning synchronization, so + they are locked. Tick the box above only if you intend to override them. +
