prometheus remote write to opentelemetry

[sylr]

Hi,

I'd like to know if it is possible to forward prometheus metrics using a remote write endpoint in vector and push them to an opentelemetry-collector endoint.

I tried this:

---
data_dir: /vector-data-dir
api:
  enabled: true
  address: 127.0.0.1:8686
  playground: false
sources:
  prometheus_remote_write:
    type: prometheus_remote_write
    address: 0.0.0.0:9090
sinks:
  opentelemetry_collector:
    type: opentelemetry
    inputs:
    - prometheus_remote_write
    protocol:
      uri: http://opentelemetry-collector.monitoring.svc.cluster.local:4317
      type: http
      encoding:
        codec: otlp
      batch:
        max_bytes: 10000000

But I get the following error:

2025-12-17T11:25:15.304928Z  INFO vector::app: Log level is enabled. level="info"
2025-12-17T11:25:15.305588Z  INFO vector::app: Loading configs. paths=["/etc/vector"]

Thank you.
