Architecture: Policies and Datasets

Policy Service (orb-policies)

This microservice is responsible for:

• Agent Policy management
  • /policies/agent User facing CRUD management of Agent Policies
  • produce system events during dataset CRUD actions for consumption by other microservices, esp Fleet which communicates with the agents on policy events
  • expose gRPC API for policy retrieval by other services
• Dataset management
  • /policies/dataset User facing CRUD management of Datasets
  • produce system events during dataset CRUD actions for consumption by other microservices, esp Fleet which communicates with the agents on dataset events
  • consult Sink service via gRPC to verify Sink ID
  • consult Fleet service via gRPC to verify Agent Group ID
  • verify agent policy ID
  • expose gRPC API for dataset ID to sink ID mapping for sink services. This is so that sink consumers (like Prometheus) know which in configuration to use for which dataset

Agent Policy Data Model

DB Field	JSON Field	Public	ReadOnly	Description
id	id	X	X	UUIDv4 (known as mf_thing_id in the internal models because it comes from the mainflux thing id)
mf_owner_id				UUIDv4 tenant owner ID
name	name	X		A name label field

| tags | orb_tags | X | | Orb tags field: defined through the API or UI | | ts_created | ts_created | X | X | A timestamp of creation |
