      • OpenTelemetry data model transforms has not consumers
      • After configuring the Logging v6.3 for log forwarding to Loki v6.3 using the OpenTelemetry data model as documented  [1], collector pods are streaming the following warning message:
         [1] https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html/logging/logging-6-2#quick-start-opentelemetry_logging-6x-6.2

NAME                                    DISPLAY                          VERSION     REPLACES                                PHASE
cluster-logging.v6.3.0                  Red Hat OpenShift Logging        6.3.0                                               Succeeded
cluster-observability-operator.v1.1.1   Cluster Observability Operator   1.1.1       cluster-observability-operator.v1.1.0   Succeeded
loki-operator.v6.3.0                    Loki Operator                    6.3.0                                               Succeeded

      Steps to Reproduce:

      1. Deploy CLO v6.3 and Loki v6.3, and configure Loki with schema version v13.
      2. Create a clusterLogForwarder custom resource with following configuration:
      apiVersion: observability.openshift.io/v1
kind: ClusterLogForwarder
metadata:
  name: collector
  namespace: openshift-logging
  annotations:
    observability.openshift.io/tech-preview-otlp-output: "enabled"  
spec:
  managementState: Managed
  outputs:
    - lokiStack:
        authentication:
          token:
            from: serviceAccount
        dataModel: Otel
        target:
          name: logging-loki
          namespace: openshift-logging
      name: default-lokistack
      tls:
        ca:
          configMapName: openshift-service-ca.crt
          key: service-ca.crt
      type: lokiStack
  pipelines:
    - inputRefs:
        - application
        - infrastructure
        - audit
      name: default-logstore
      outputRefs:
        - default-lokistack
  serviceAccount:
    name: collector

      3.  Check the collector pod logs.

       

      Current Results:

      • All collector pods are streaming the following warning message:
      Starting Vector process...32025-06-11T13:30:03.690383Z WARN vector::config::loading: Transform "output_default_lokistack_application_reroute._unmatched" has no consumers42025-06-11T13:30:03.690407Z WARN vector::config::loading: Transform "output_default_lokistack_audit_reroute._unmatched" has no consumers52025-06-11T13:30:03.690410Z WARN vector::config::loading: Transform "output_default_lokistack_infrastructure_reroute._unmatched" has no consumers62025-06-11T13:30:03.690414Z WARN vector::config::loading: Transform "output_default_lokistack_route._unmatched" has no consumers

      Expected results:

      Not expected to see any WARN related to the transforms created and not consumed
