    read_timeout: 60s
processors:
  batch:
exporters:
  jaeger:
    endpoint: jaeger-collector:14250
    tls:
      insecure: true
service:
  pipelines:
    traces:
      receivers: [datadog]
      processors: [batch]

This is interesting, when you're looking through the UI. Do you see the service.name being added to the span attributes?

I saw the issue as well with a similar setup. I was able to work around it with the following processor, but I'm not familiar enough with the data model to understand why this worked. Something to do with the service name being set in individual spans, but not the resource?

processors:
  groupbyattrs:
    keys:
      - service.name

Edit: looks like there's another similar issue #21210

[MovieStoreGuy]

Yeah, I am just looking at creating a PR for it now but it will be a breaking change.
