The ONAP CLAMP platform abstracts the details of these systems under the concept
of a control loop model. The design of a control loop and its management is
represented by a workflow in which all relevant system interactions take
control loops, where no low-level user interaction with other components is
required.
+CLAMP also allows to visualize control loop metrics through a dashboard, in order
+to help operations understand how and when a control loop is triggered and takes action.

At a higher level, CLAMP is about supporting and managing the broad operational
life cycle of VNFs/VMs and ultimately ONAP components itself. It will offer the
ability to design, test, deploy and update control loop automation - both closed
and open. Automating these functions would represent a significant saving on
operational costs compared to traditional methods.
