OpenTelemetry- How to debug connections

I'm trying to get OpenTelemetry container to pass spans along to my Jaeger container, but haven't quite figured out, and can't tell what's wrong, either.

I have confirmed that:

• my app is generating and passing along spans to OTel
• Otel is receiving the spans

But beyond that, I see nothing that might denote that errors are occur during export to Jaeger, but no spans ever appear there. It is also hard to debug as there is a large amount of text output every ten seconds that makes it hard to scroll through and find the important bits.

Running Otel with:

/usr/bin/docker run \
  --name oqm_otel \
  -p 1888:1888 \
                           -p 8888:8888 \
                           -p 8889:8889 \
                           -p 13133:13133 \
                           -p 4317:4317 \
                           -p 4318:4318 \
                           -p 55679:55679 \
                           -v /etc/oqm/infra/otel/otel-collector-config.yaml:/etc/otel-collector-config.yaml \
                           --add-host host.docker.internal:host-gateway \
                           otel/opentelemetry-collector:0.72.0

Running Jaeger with:

 /usr/bin/docker run --name oqm_jaeger -p 8090:16686 -p 8091:14268 -d jaegertracing/all-in-one:1

/etc/oqm/infra/otel/otel-collector-config.yaml:

# Configuration for OpenTelemetry Collector within the OQM system.
receivers:
  otlp:
    protocols:
      grpc:
        endpoint: otel-collector:4317 # What does this do?

exporters:
  jaeger:
    endpoint: host.docker.internal:8091
    tls:
      insecure: true

processors:

service:
  extensions: [health_check]
  pipelines:
    traces:
      receivers: [otlp]
      processors: [batch]
      exporters: [jaeger]

Any ideas?
