  Entity graph derived from the Vector Observability gRPC message definitions.
  Vector's runtime model is a directed pipeline of Components (sources ->
  transforms -> sinks); each component exposes Outputs and ComponentMetrics.
entities:
  - name: Component
    description: A configured pipeline component (source, transform, or sink).
    key: component_id
    fields: [component_id, component_type, on_type, outputs, metrics]
  - name: Output
    description: A named output stream of a component.
    key: output_id
    fields: [output_id, sent_events_total]
  - name: ComponentMetrics
    description: Received/sent bytes and events totals for a component.
    fields: [received_bytes_total, received_events_total, sent_bytes_total, sent_events_total]
  - name: TappedEvent
    description: An event captured from a component via event tapping.
    fields: [component_id, component_type, component_kind, event]
relationships:
  - from: Component
    to: Output
    type: has_many
    via: outputs
  - from: Component
    to: ComponentMetrics
    type: has_one
    via: metrics
  - from: TappedEvent
    to: Component
    type: belongs_to
    via: component_id
enums:
  ComponentType: [SOURCE, TRANSFORM, SINK]
  MetricName: [received_events_throughput, sent_events_throughput, received_bytes_throughput, sent_bytes_throughput, received_events_total, sent_events_total, received_bytes_total, sent_bytes_total, errors_total]
