TODO: Capture the components that can export to logging
The CLAMP Logging functional entity provides the capability to manage runtime control loopscapture information required to operate, troubleshoot and report on the performance of the ONAP platform. It provides the capability to
- Create control loop from DCAE blueprint sent by SDC
- Create configuration policy from the policy Tosca sent by SDC
- Configure DCAE applications of the control loop
- Associate µService configuration policies to the DCAE application
- Configure the operations to be taken by the control loop (by creating/updating/deleting operational policies)
- Deploy/un-deploy control loop flow (blueprints) to DCAE
- Control loop visualization.
CLAMP relies on Policy to communicate to App-C/VF-C/SDN-C/SO in runtime, hence these are not part of CLAMP can :
- Display logging analytics
- Provide centralized logging information from distributed ONAP components
- Coorelate and track a external client request as it traverses the ONAP components.
Note: The logging data reception information is provided by the support of the logging source using a component.
2. API definitions
CLAMP provides LOGGING provides the following interfaces:
| Interface Name | Interface Definition | Interface Capabilities | ||||
|---|---|---|---|---|---|---|
| CLAMPELOGE-1 | Control Loop Lifecycle Management Interface. | A user interface for:
| CLAMPE-2 | Control loop dashboard. User interface to show the overall status of the control loop through DMAAP events | Logging data reception interface | Provides the ability of the logging source to export logged data |
| LOGE-2 | Logging Anaytics visulization interface | Provides the ability to display and query logging information. |
Note: xxxI interface is a Component internal interface. xxxxE interface is a component external interface
The current API documents can be found at:
The provided UI interfaces are found at: CLAMP latest user guide
- CLAMP internal APIs can be found: clamp swagger pdf
CLAMP As the LOGE-1 interfaces is a replication of internally stored log data, there is not a specification interface in a traditional sense. Logging guidelines can be found at: https://docs.onap.org/en/casablanca/submodules/logging-analytics.git/docs/Logging_Enhancements_Project/logging_enhancements_project.html?highlight=log
Logging consumes the following Interfaces:
| Interface Name | Purpose Reason For Use | ||
|---|---|---|---|
| SDCE-6 | To receive the Control Loop Blueprint from SDCTo receive | ||
| PolicyE-2 | To create and configure the closed Loop Operational Policies and Configuration policies(DCAE Aps. Config.)|||
| - | x Retrieve DCAE appplication statusDCAEE | - | y Deploy/remove DCAE application.

- Service model (received from SDC)
- VNF model (received from SDC)
- Policy Model.

7. New Capabilities in this Release
This release, CLAMP LOGGING adds the following Capabilities:
- Introduction of the model driven approach for Control Loops
- add policy-model to the SDC distribution
- automatic rendering of configuration policy UI based on the distributed policy model
- better rending of the display of the control loop flow based on the distributed blueprint
- enhanced internal model to better support model driven approach.
