Analytics Stream Output Attributes

Hello everyone.

I'm studying the new ai features from ODC and its capabilities, and when I was testing some use cases i got into the following question:

Where can i see the complete list of output attributes produced when using the analytics stream to trace agents?
The reason for this question is the fact that my client wants to export and evaluate agents from outsystems using external tools/evaluators, but this evaluators require some specific agent attributes for example "agent.id", "input.messages", etc.

The focus is to evaluate the agent automatically and not manually creating a dataset using its prompts, inputs outputs, etc.

In this link i didnt find detailed information related to this matter:
https://success.outsystems.com/documentation/outsystems_developer_cloud/monitoring_and_troubleshooting_apps/streaming_observability_data/configure_analytics_streams_in_the_odc_portal/


Thank you for your time.

Currently, OutSystems does not provide a fully documented list of all analytics stream attributes generated for AI agents/traces in ODC. The analytics stream mainly follows OpenTelemetry-style observability data, but many agent-specific fields such as agent.id, input.messages, prompts, tool calls, and outputs may vary depending on the AI feature being used and the exporter configuration. In practice, the best way to discover the available attributes is to inspect the actual streamed payloads in your analytics destination (for example Azure Event Hub, Datadog, Elastic, or another OTEL-compatible sink). You can then map those fields to your external evaluator requirements. At the moment, OutSystems documentation only explains how to configure analytics streams and does not expose a complete schema reference for AI tracing attributes. If your client needs automated evaluation with external frameworks, you may also need to enrich traces manually by adding custom metadata/logging around agent execution until OutSystems provides more detailed observability support for AI agents.
