一、修改otelcol-config.yaml

receivers:
  otlp:
    protocols:
      grpc:
        endpoint: 0.0.0.0:4317
      http:
        endpoint: 0.0.0.0:4318
exporters:
  debug:
    verbosity: detailed
  otlp/jaeger: # Jaeger supports OTLP directly
    endpoint: 192.168.31.161:4317
    tls:
      insecure: true
  otlphttp/prometheus: # the PRW exporter, to ingest metrics to backend
    endpoint: http://192.168.31.160:9090/api/v1/otlp
    tls:
      insecure: true
  elasticsearch:
    endpoints: [http://192.168.31.161:9200]
    logs_index: otel-logs-{service.name}-{yyyy.mm.dd}
    traces_index: otel-traces-{service.name}-{yyyy.mm.dd}
service:
  pipelines:
    traces:
      receivers: [otlp]
      exporters: [otlp/jaeger,elasticsearch]
    metrics:
      receivers: [otlp]
      exporters: [otlphttp/prometheus,elasticsearch]
    logs:
      receivers: [otlp]
      exporters: [debug,elasticsearch]

二、 Program.cs

运行效果：
