Overview
Restconf collector is a microservice in ONAP DCAE. It subscribes to external controllers
and receives event data. After receiving event data it may modify it as per usecase's requirement and
produce a DMaaP event. This DMaap event usually consumed by VES mapper.
Restconf Collector can subscribe multiple events from multiple controllers.
Below diagram shows restconf interaction with an external controller.
Use cases:
- BBS
* RestConf collector(RCC) subscribe for ONT (Optical network terminal) registration event from 3rd
party Access Controller.
* RCC requests to set up a persistent connection with the controller.
* As the connection is standing, Access controller pushes registration event to RCC.
* RCC receives event, convert it JSON event, modify and append some user data and publishes on
DMaap with topic of DCAE_RCC_OUTPUT.
* Ves Mapper consumes this event, convert it to VES event using Mapper
file. - CCVPN
* RestConf Collector (RCC)subscribes for remote failure alarm to SOTN Controller (SC)
* RCC requests to set up a persistent connection with the 3rd party Controller.
* As the connection is standing, SC pushes service route status data to the collector
* RCC receives alarm data, converts it into JSON format and publishes on DMaap with topic of
ROUTE_ALARM_OUTPUT
* VES Adapeter consumes the alarm message
* VES requests the RestConf2VES mapping from the mapper. As of CCVPN use case proposal,
the RestConf2VES.xml is manually uploaded to the mapper.
* Mapper response back the mapping
* UVA converts json alarm into VES event
* UVA publishes the VES event on DMAAP for further correlation

Deployment Steps
| Task | |
|---|---|
| Download code | git clone https://gerrit.onap.org/r/dcaegen2/collectors/restconf [Modify the configuration parameters if required. Update the security files.] |
| Build | mvn clean install |
| Run | docker run onap/org.onap.dcaegen2.collectors.restconfcollector |
| Using cloudify | Install : cfy blueprints validate /<blueprints-file-path>/k8s-rcc-policy.yaml cfy blueprints upload -b restconfcollector /<blueprints-file-path>/k8s-rcc-policy.yaml cfy deployments create -b restconfcollector cfy executions start -d restconfcollector install Un Install: cfy uninstall restconfcollector cfy deployments delete -f restconfcollector cfy blueprints delete restconfcollector |
Validation
Check if component is running.
The logs are stored in /opt/app/restconfcollector/logs/collector.log

user-f79d0 - Few comments based on the demo today; please address them
1) Add steps to simulate/validate the flow (relevant postman and examples)
2) Update Blueprint version (plugin version not current) and include ccvpn blueprint/configuration as reference
3) Specify on documentation Event standards supported
Future work
a) Control Loop flow onboarding/integration – SDC/CLAMP/Policy
b) Multiple controller/truststore - AAF integration
e) Scaling work TBD

Hi user-f79d0, do we need to update the installation steps here or create a new wiki page for Frankfurt release? e.g. which image we use 1.2.1-SNAPSHOT?

Hi David Perez Caparros user-f79d0, can you please also update how to build docker image? As I do not see Dockerfile in the restconf repo. Is there some other approach?
