At first glance, it appears to me that you aren't using the datadog-agent, especially given the two following pieces of information:
"agent_url": "collector:4317"
[...]
Diagnostics
agent_error => Received HTTP/0.9 when not allowed
Diagnostic checks => failedAs illustrated in this documentation, to leverage the Datadog instrumentation, you'll need to use the Datadog Agent. This way, you'll be able to get both OTel-generated and DDog-generated spans in the Datadog UI.
I believe you should be able to install the Datadog Agent for your docker application using our public documentation (e.g., this one), but I'll be here to help you out if you need any help in the process 😃
For instance, if you are using docker compose and want to trace a service called wordpress, you could fundamentally have the following:
Your datadog-agent service:
datadog-agent:
image: datadog/agent:latest
environment:
DD_API_KEY: <your API key>
DD_SITE: <your site, certainly datadoghq.com or datadoghq.eu>
DD_LOGS_ENABLED: true
networks:
- default
volumes:
- /var/run/docker.sock:/var/run/docker.sock:ro
- /proc/:/host/proc/:ro
- /sys/fs/cgroup/:/host/sys/fs/cgroup:ro
#- /opt/datadog-agent/run:/opt/datadog-agent/run:rwand your traced wordpress service:
wordpress:
image: whatever
networks:
- default
environment:
<OTel configs, for instance>
DD_AGENT_HOST: datadog-agent
DD_TRACE_OTEL_ENABLED: true
<Other DD configs as needed, for instance>
depends_on:
- datadog-agentThis is just an example, but this should give you the rough picture :)

Bug report
I have followed the instructions for OTEL tracing. I used out-of-the-box setup for PHP as instructed here https://docs.datadoghq.com/tracing/trace_collection/automatic_instrumentation/dd_libraries/php/
and set
DD_TRACE_OTEL_ENABLEDtotrueI am running PHP 8.0-fpm and Wordpress. I have a Docker run OTEL collector with the Datadog exporters created.
I am not seeing any tracing. If I add OTEL's SDK for tracing, then I see some rudimentary spans. But still nothing from Datadog tracer. I even set the agent to the OTEL collector, as its not clear how you get/set the collector URI.
Do you have a tutorial somewhere where I can see how you got this working clearly? I saw in this PR https://github.com/DataDog/dd-trace-php/pull/2332 very clear view of data in Jaeger and Datadog and would love you know how this was setup correctly.
