Use Cases

When using the elasticsearch sink, it is possible to specify multiple endpoints:

• https://vector.dev/docs/reference/configuration/sinks/elasticsearch/#endpoints

However, when the sink fails to connect to one of them, there is no indication as to which endpoint it is (json log message prettified for clarity):

{
  "timestamp": "2024-11-06T11:18:12.759382Z",
  "level": "WARN",
  "message": "HTTP error.",
  "error": "error trying to connect: tcp connect error: Connection refused (os error 111)",
  "error_type": "request_failed",
  "stage": "processing",
  "internal_log_rate_limit": true,
  "target": "vector::internal_events::http_client",
  "span": {
    "name": "http"
  },
  "spans": [
    {
      "component_id": "sink_elasticsearch",
      "component_kind": "sink",
      "component_type": "elasticsearch",
      "name": "sink"
    },
    {
      "request_id": 2,
      "name": "request"
    },
    {
      "name": "http"
    }
  ]
}
