How to edit the application.yml to revice the trace form opentelemetry-agent

[itnikc]

I want to use opentelemetry-agent collect the trace metric and logs,then send to Skywalking.I try to do it for a long time,but fail.I use the 10.4.0 version,and my config like

receiver-otel:
  selector: default
  default:
    enabledHandlers: "otlp-traces,otlp-metrics,otlp-logs"
    enabledOtelMetricsRules: "apisix,nginx/*,k8s/*,istio-controlplane,vm,mysql/*,postgresql/*,oap,aws-eks/*,windows,aws-s3/*,aws-dynamodb/*,aws-gateway/*,redis/*,elasticsearch/*,rabbitmq/*,mongodb/*,kafka/*,pulsar/*,bookkeeper/*,rocketmq/*,clickhouse/*,activemq/*,kong/*,flink/*,banyandb/*,envoy-ai-gateway/*"

. Then my vm variable is -javaagent:D:\opentelemetry-javaagent.jar
-Dotel.service.name=xxxxx-gateway
-Dotel.traces.exporter=otlp
-Dotel.metrics.exporter=otlp
-Dotel.logs.exporter=otlp
-Dotel.exporter.otlp.endpoint=http://host:4317
-Dotel.exporter.otlp.protocol=grpc
-Dotel.logs.mdc.enabled=true`.However the 4317 port is not enabled.

why 4317? Doc never declared this. Ref to https://skywalking.apache.org/docs/main/latest/en/setup/backend/otlp-trace/

You also could ask AI to get this.
OTel traces are received on the OAP gRPC port, which by default is 11800. This is the same oap.external.grpc.port used by native agents and OTLP (OTel) traffic.
