LLMObs Team Review
Nice work aligning the Java SDK payloads with the intake schema — this is a big step for system test compliance. A few items to address/clarify below (inline), plus some overall notes:
Test Coverage Notes
What's well-covered: LLMObsSpanMapperTest expansion is great — covers _dd map, nested meta.error, map-based input with prompt/chat_template, tool definitions, tool calls + tool results. The decorator tests verify the new tags (source, integration, error, ddtrace.version).
Gaps to consider:
- Error paths: No test exercises the error-path defaults (model_name and empty output set during
withResponseCreateParamswhen the HTTP call fails). A test where the response errors out and verifying the span still hasmodel_nameand placeholder output would be valuable. - Prompt tracking:
enrichInputWithPromptTracking(),extractChatTemplate(),extractPromptFromParams(), andnormalizePromptVariable()have no unit tests. Template variable replacement edge cases (overlapping values, empty variables, image/file fallbacks) would increase confidence. - Custom/MCP tool calls:
ToolCallExtractor.getToolCall(ResponseCustomToolCall)andgetToolCall(McpCall)are new with no unit tests. JsonValueUtils: New utility class with no dedicated tests for recursive JSON-to-Object conversion.
Questions
- The min version bump from
3.0.0to3.0.1— what API was missing in3.0.0? This affects which customer versions get instrumented. - For the
_ddmap — does the intake expectapm_trace_idto equaltrace_id? In other SDKs these can differ (APM trace ID vs LLMObs ID).

The top-level error: 0/1 integer field has been removed and replaced with status: "ok"/"error" + error details nested under meta.error. Can you confirm no downstream consumers (EvP remapper, indexer facets, etc.) read error from the top level? This is a payload shape change that could be breaking if anything depends on the old field.

This change is dictated by the TestOpenAiLlmInteractions::test_chat_completion assertion. I assume that the system test assertions are correct. Have they been verified as being compliant with the requirements of downstream consumers?

If I leave the top-level error field, the system test will fail.

What Does This Do
Aligns OpenAI Java LLMObs span payloads with expected intake/system-test schema by:
_ml_obs_tag.integration_ml_obs_tag.source_ml_obs_tag.ddtrace.version_ml_obs_tag.error_ml_obs_tag.error_typemodel_name(and stable placeholder output where applicable) is set on error paths forchat/completions/embeddings/responses.
input.prompt,variables,chat_template)tool_definitions)stream,tool_choice,text.verbosity, etc.)_ddmap with span/trace idsmeta.errorinputserialization (messages+prompt)tool_definitionsintometa.Motivation
OpenAI/LLMObs system tests exposed schema and tag mismatches in Java payloads (especially response spans, tool metadata, error mapping, and prompt tracking structure). This change brings Java output in line with expected LLMObs intake contract and behavior.
