The implementation for this issue is actually in the OTEL/contrib/jaegerreceiver module. By convention Jaeger internal extensions try to log which ports / endpoints they are listening when creating the servers, e.g.:

• Serving metrics {"address": "localhost:8888", "metrics level": "Detailed"}
• Query server started {"kind": "extension", "name": "jaeger_query", "http_addr": "[::]:16686", "grpc_addr": "[::]:16685"}
• Starting GRPC server {"kind": "extension", "name": "jaeger_query", "port": 16685, "addr": ":16685"}
• Starting HTTP server {"kind": "extension", "name": "jaeger_query", "port": 16686, "addr": ":16686"}

(side note: the log from Query server should be split into two lines)

However, the jaegerreceiver that we're importing from OTEL/contrib is not logging any of the ports / endpoints, even though in all-in-one configuratiob we enable all four:

      grpc:
        endpoint: "${env:JAEGER_LISTEN_HOST:-localhost}:14250"
      thrift_http:
        endpoint: "${env:JAEGER_LISTEN_HOST:-localhost}:14268"
      thrift_binary:
        endpoint: "${env:JAEGER_LISTEN_HOST:-localhost}:6832"
      thrift_compact:
        endpoint: "${env:JAEGER_LISTEN_HOST:-localhost}:6831"

The goal is to make changes upstream to log a similar "Server started" log for each port that jaegerreceiver is listening to. For the reference of how it's done we can look at OTLP receiver that does log its endpoints:

• Starting GRPC server {"kind": "receiver", "name": "otlp", "data_type": "traces", "endpoint": "localhost:4317"}
• Starting HTTP server {"kind": "receiver", "name": "otlp", "data_type": "traces", "endpoint": "localhost:4318"}
