Controller Services are available for reporting tasks, processors, and other services to utilize for configuration or task execution. You can use the NiFi UI to add Controller Services for either reporting tasks or dataflows.

Your ability to view and add Controller Services is dependent on the roles and privileges assigned to you. If you do not have access to one or more Controller Services, you are not able to see or access it in the UI. Roles and privileges can be assigned on a global or Controller Service-specific basis.

Controller Services are not reporting task or dataflow specific. You have access to the full set of available Controller Services whether you are adding it for a reporting task or a dataflow.
