CC @wbpcode I thought about adding this, as I have been experiencing some users having problems with Istio where the config "looks OK" but no spans are received by the back-end. Having such log can help in troubleshooting. I saw there's a OTel stat sink, but that can only be exported via gRPC which is not always helpful, specially for those who use a back-end that does not support OTLP/gRPC. I opened a separated issue for it: #37826 |

Commit Message: Log (debug) the number of exported spans
Additional Description:
Adds a debug log message containing the number of (about to be) exported spans. This is helpful in troubleshooting for cases where the configuration looks "correct" but no spans are seen in the tracing back-end. The stats sink could be used, but that only exports via OTLP/gRPC which is not always possible.
