Process Flow
- Service Instantiation completion event is published
- Context Aggregator receives the event
- Context Aggregator initiates calls to various Context Builders to get normalized data from platform components.
- Context Aggregated payload is published into event bus
- Rule Processing engine receives that event and activates audit rules processing
- The result of audit rules processing is published into Event Bus
- Audit Result payload is consumed by synapse service
- The result is inserted into data storage / ES via search service
- Reporting tool such as Kibana displays the data

SDN-C Context Builder
SDN-C Context Builder is aimed to encapsulate the functionality of accessing SDN-C via RESTful APIs and transform the data into common model structure used by audit process.

Network Discovery Context Builder
The Network Discovery Context Builder is aimed to encapsulate the functionality of accessing the Openstack API via RESTful APIs and transform the data into common model structure used by audit process.

Context Aggregator
Context Aggregator is a microservice that orchestrates the calls to various context builders which are pluggable into POMBA upon receiving the Orchestration Completion Event from Message Router.

Validation Service + Rule Processing
Validation service is a core A&AI microservice which implements a rule processing engine.
POMBA configures and deploys its own instance of validation service that consumes and publishes to POMBA topics in DMaaP.
Audit rules are stored in groovy format file. The file is files are injected into a service and rules are processed by the engine.
Currently audit rules are hand crafted, but eventually will be sourced from well formed ASDC models and from Data Dictionary. Existing rules are listed here.
POMBA will eventually support the mechanism of separting separating rules from validation service code, thereby allowing changing the rules rule updates without a rebuild or restart of the validation service.
The text of the message displayed for each violation will be kept separately to allow text change without touching the code
