raw_http subscriber

POSTs enriched events as JSON to any HTTP endpoint. Good for AWS Lambda function URLs, generic HTTP receivers, or the upstream OTel Collector's webhookevent receiver. For native OTLP delivery use the otel subscriber.

Add to the subscribers block in config.yaml:

subscribers:
  raw_http:
    enabled: true
    url: "https://my-endpoint.example.com/events"
    method: "POST"
    headers:
      Authorization: "Bearer my-token"
      X-Custom-Header: "my-value"
    batch_size: 1            # 1 = one event per request; >1 = JSON array batching
    flush_interval: 5s
    skip_verify: false
    workers: 1               # parallel HTTP POSTs (raise for slow endpoints)
    buffer_size: 1000
    # Per-event filter — drop before batching/compaction. include is any-of,
    # exclude is none-of. See ../ "Per-Subscriber Filtering".
    include: []
    exclude: []
