-Open Closed loop in CLAMP
+Closed loop in CLAMP
-------------------------
There is 2 closed loop levels in CLAMP:
+
- Closed loop template: This is created from the DCAE blueprint (designed in the DCAE designer), and distributed by SDC to CLAMP.
- Closed loop instance: Based on the template, it represents a physical closed loop in the platform related to a service and a VNF.
- This is created in CLAMP when receiving the SDC notification, as this one is related to a specific service/vnf.
+ This is created in CLAMP when receiving the SDC notification, as this one is related to a specific service/vnf.
There is no way to design a closed loop from scratch in CLAMP, you can only configure it and manage its life-cycle.
For more info on how to design the service in SDC, check this: https://wiki.onap.org/display/DW/CLAMP+videos#CLAMPvideos-DesignpartinSDC
|clamp-open-box|
-Once the distributed closed loop has been chosen, the closed loop is shown to the user
+Once the distributed closed loop has been chosen, the closed loop is shown to the user.
+From this view user can start configure empty closed loop using **Closed loop modeller**.
|clamp-opened-closed-loop|
+Closed loop modeler has 3 main parts:
+
+#. Loop configuration view
+ Visualizes event flow in Control Loop. This view is auto-generated by Clamp. To generate it Clamp parses DCAE_INVENTORY_BLUEPRINT from CSAR distributed by SDC.
+ It Always consists of **VES -> <nodes from blueprint> -> OperationalPolicy**. Not all nodes are visualized. Only those with type **dcae.nodes.\***
+ |blueprint-node|
+
+#. Loop status
+ Visualizes status of opened loop.
+#. Loop logs
+ Table with log data of opened loop
+
Closed Loop properties
----------------------
-You can check to which service/vnf the closed loop has been associated in SDC.
+In Dublin release this view shows what are deployment parameters or Closed Loop.
+To open it from *Closed Loop* menu select *Properties CL*
|clamp-menu-prop|
-This opens a box that gives the properties set during the SDC notification deployment in CLAMP.
-Do not change those settings
+This opens a box with JSON object. It contains deployment parameters extracted from DCAE_INVENTORY_BLUEPRINT.
+It's not recommended to edit this JSON. Each of this parameters should be available in view shown to deploy analytic application.
+
|clamp-prop-box|
-Operational policy properties
+Operational and Guard policy properties
-----------------------------
-The box "policy" is clickable, so the operational policies can be defined.
-By clicking on the button "New Policy", it's possible to add new operational policies that can chosen in the configuration policy.
+Operational policy is a parametrized drools (in Dublin) rule with logic performing action on resource.
+User can't chose his own rule. Clamp always tries to create operational policy that bases on rule bind with **ClosedLoopControlName** attribute available in Policy dictionary.
+
+There is only one operational policy per closed loop. More about operational policies can be found here `Control Loop Operational Policy <https://wiki.onap.org/display/DW/Control+Loop+Operational+Policy>`_.
+
+Guard policy is policy securing operational policy calls. It defines a set of constraints that have to be matched before running operational policy.
+More about guard policies can be found here `Creating and Using Guard Policies <https://docs.onap.org/en/dublin/submodules/policy/engine.git/docs/platform/guardpolicy.html>`_.
-|clamp-op-policy-box|
+To configure operational and guard policy user has to click *OperationalPolicy* box.
-Once clicked, it's possible to configure each operational policy that can also contain multiple "sub policies", one per Recipe
+Once clicked, it's possible to configure operational policy. Policy can have child policies, one per Recipe.
|clamp-op-policy-box-policy1|
-Configuration policy properties
+1. Parent policy name
+2. Global time limit for this operational policies
+3. Specifies whether policy is abated
+4. Unique id for Control Loop.
+5. Button for creating child/parent policies
+6. Unique id of Policy. (Clamp internal)
+7. Recipe/Operation triggered on controller/orchestrator
+8. Maximum count of retries
+9. Timeout for this operational policy
+10. Actor used to perform action. (Orchestrator/Controller)
+11. Payload required by actor to perform an action
+12. Set of fields with policies called under certain conditions. E.g. when health-check receives timeout failure restart could be called.
+13. Set of fields specifying resource. On this resource Operational Policy should perform an action
+14. Checkbox enabling/disabling guard policy for this operational policy
+15. Guard Policy type (frequency limited or min max)
+16. Set of guard policy specific fields. Please check `Creating and Using Guard Policies <https://docs.onap.org/en/dublin/submodules/policy/engine.git/docs/platform/guardpolicy.html>`_.
+
+
+Micro-service policy properties
-------------------------------
-The box "tca" is clickable, so the TCA configuration policy can be defined.
-In that popup dialog, multiple Thresholds can be defined, the operational policies defined previously can be chosen and set in the "Policy" field.
-
+Boxes between `VES` and `OperationalPolicy` are generated from blueprint. They can be one of ONAP predefined analytic microservices or custom analytics.
+Each of the boxes is clickable. Microservice configuration view is generated using Policy Type assigned to selected microservice.
+Clamp by default assumes that microservices have policy type **onap.policies.monitoring.cdap.tca.hi.lo.app**.
+
+After clicking microservice box Clamp opens popup dialog. Example popup dialog for microservice with default type looks like:
+
|clamp-config-policy-tca1|
+|clamp-config-policy-tca2|
+
+
Saving Closed loop
------------------
-Once all properties have been defined for all policies, the closed loop must be saved.
+Policies are saved localy in Clamp after each configuration change
-|clamp-save-cl|
Submitting the Closed loop to policy
------------------------------------
In the "Manage Menu", the submit action can be used to send the configuration to policy engine.
-The "Validation test" can be used to check the data configured in the closed loop without sending anything to policy engine.
+
|clamp-submit-cl|
-If everything is successful, this changes the status to "Distributed"
+If everything is successful, this changes the status to "Submitted". Clamp should also show proper logs in logs view.
|clamp-distributed|
+After Policies are submitted they should be visible in Policy PAP component.
+Please check `Policy GUI <https://docs.onap.org/en/dublin/submodules/policy/engine.git/docs/platform/policygui.html>`_
+
Deploy/undeploy the Closed loop to DCAE
---------------------------------------
Once sent to policy engine, Clamp can ask to DCAE to deploy the micro service
