  title: Jaeger Collector API (api_v2) CollectorService Sampling Manager API
  version: '2.0'
  description: 'Jaeger Collector ingest API. The Collector accepts span batches over gRPC

    on port 14250 (`jaeger.api_v2.CollectorService`) and over the HTTP gateway

    at `/api/v2/spans`. Jaeger v2 (since November 2024) also accepts OTLP

    natively on ports 4317 (gRPC) and 4318 (HTTP) and Zipkin on 9411; this

    spec documents the native legacy api_v2 surface.'
