Design a closed loop template and associate it to a Service, - the template represents the theoretical flow of the CL. (DCAE-DS/SDC) - - #. generate a deployment artifact that can be ingested by the DCAE, - today it is a "cloudify" blueprint. - - #. Distribute the control loop to CLAMP and DCAE, the csar is distributed - to CLAMP, the blueprint is distributed to both CLAMP and DCAE. (SDC) - #. Submit the closed loop, meaning provision Policy/DCAE with - closed loop data. (CLAMP) - #. Deploy the closed loop, it initiates the deployment of the micro - service on DCAE side (CLAMP) - -*Release 1 (Amsterdam)* includes control loop template designer in Clamp UI. - -*Release 2 (Bejing)* does not include the control loop template designer -in Clamp UI, this is implemented in DCAE-DS. - -**Steps** - - * `Design a Model`_ - * `Configure Collector`_ - * `Configure Alarm Detector`_ - * `Configure Data Analytics Function`_ - * `Configure Policy`_ - * `Distribute the Model`_ - * `Open Loop Design`_ - -Design a Model --------------- - -.. note:: - When required, contact the DCAE Group (see `Mailing Lists <https://wiki.onap.org/display/DW/Mailing+Lists>`_) to - confirm that a blueprint for the Service has been generated and - is available on DCAE. - -**Prerequisites:** Create and test a VF -(see :ref:`VF Creation and Testing <user-guides-service-design>`). - - #. Create and name a new model - #. Associate a Service with the model - #. Based on the service, provide values for its attributes - #. Select the Resource-VF and Resource-VFC to associate with the model - #. Select one or more locations in the cloud where the - closed loop will be deployed - #. Here is a view of a hypothetical visual design tool - showing loop modeling components: - - |image0| - - #. Use the tool to select and connect components, - thus defining the structure of the model - #.
