Management Agents require group membership and policies to interact with OCI services:
AgentUsersGrp (A): A predefined dynamic group for all Management Agents in a tenancy. With an
attached policy granting upload permissions (e.g., allow dynamic-group AgentUsersGrp to use
discovery-service-family in tenancy), agents can send data to the discovery service for resource
detection.
Why not B, C, or D?
B and C: Specific to Stack Monitoring roles, not general agent uploads.
D: A generic name, not a predefined OCI group.
AgentUsersGrp is the standard for this purpose.
