Architecture

Pipeline:

Config -> Topology -> Persona -> Session -> Event -> FlowRecord -> Encoder -> UDP

Core packages:

• internal/config: YAML loading, defaults, and validation.
• internal/scenario: scenario selection and session/event generation.
• internal/sessiontemplate: ordered enterprise and security templates.
• internal/model: protocol-neutral FlowRecord.
• internal/protocol/*: NetFlow v5, NetFlow v9, IPFIX, and sFlow v5 encoders.
• internal/generator: per-exporter encoder dispatch and UDP sending.
• internal/observability: status and metrics endpoints.
