一、编写配置

nano /root/otelcol-config.yaml
==================================================
receivers:otlp:protocols:grpc:endpoint: 0.0.0.0:4317http:endpoint: 0.0.0.0:4318
exporters:debug:verbosity: detailed
service:pipelines:traces:receivers: [otlp]exporters: [debug]metrics:receivers: [otlp]exporters: [debug]logs:receivers: [otlp]exporters: [debug]
==================================================

 启动

docker run -d --name opentelemetry-collector -v /root/otelcol-config.yaml:/etc/otelcol-contrib/config.yaml -p 1888:1888 -p 8888:8888 -p 8889:8889 -p 13133:13133 -p 4317:4317 -p 4318:4318 -p 55679:55679 otel/opentelemetry-collector-contrib:0.117.0

4317:4317 # OTLP gRPC receiver
4318:4318 # OTLP http receiver
