feat(oci-genai): add OCI Generative AI instrumentation - #4483
Adds opentelemetry-instrumentation-oci-genai, instrumenting the OCI Python SDK's GenerativeAiInferenceClient (chat, generate_text, embed_text, rerank_text) with the current OTel GenAI semantic conventions, following the Bedrock/Groq packages: {operation} {model} span names, gen_ai.provider.name = oracle_cloud.generative_ai (the value proposed in open-telemetry/semantic-conventions-genai#526 and adopted by LiteLLM's OTel v2 callback and OpenLIT), gen_ai.request.*, gen_ai.response.*, gen_ai.usage.*, and content-gated gen_ai.input.messages / gen_ai.output.messages / gen_ai.system_instructions.
GENERIC (Meta, OpenAI, Google, xAI), COHERE and COHEREV2 chat formats, including tools, images and reasoning content
SSE streaming: the span completes when response.data.events() is consumed; text and tool-call deltas, finish reason and is_include_usage token counts are aggregated
on-demand and dedicated (endpoint_id) serving modes; server.address from the client endpoint
embeddings (gen_ai.embeddings.dimension.count, input count and type) and rerank (top_n, document count; rerank is used as the operation name since semconv has no value for it)
span-attribute mode (default) and event mode (use_attributes=False); gen_ai.client.token.usage and gen_ai.client.operation.duration metrics
registered in traceloop-sdk (Instruments.OCI_GENAI, guarded by is_package_installed("oci"); inference.generativeai added to the excluded URLs so the requests/urllib3 instrumentors do not double-trace), root README providers list, .cz.toml, dependabot
Verification
Live against OCI Generative AI in us-chicago-1 with an in-memory exporter, then exported to Arize Phoenix over OTLP:
chat meta.llama-3.3-70b-instruct non-streaming and streaming (38 SSE events): provider oracle_cloud.generative_ai, operation chat, gen_ai.oci.api_format=GENERIC, gen_ai.oci.serving_mode=ON_DEMAND, request/response model, gen_ai.is_streaming, finish reason stop, usage 42/2/44 (the streaming span takes usage from the trailing usage event)
chat cohere.command-a-03-2025 with preamble and two-turn history: api_format=COHERE, gen_ai.system_instructions, roles user/assistant/user
chat openai.gpt-5.4 with max_completion_tokens: mapped to gen_ai.request.max_tokens, cache-read and reasoning token attributes present
embeddings cohere.embed-v4.0: dimension count 1536, input count/type, input tokens only (OCI reports no completion tokens for embeddings)
rerank cohere.rerank-v4.0-fast: top_n, document count, ranks as output messages
generate_text returns 404 "The requested API is not available" in the commercial realm for both runtimes, so it is covered by mocked tests only
Phoenix, attributes of the streaming Llama span:
Traces list (two chat spans and one embeddings span):
Tests: uv run pytest tests/ --record-mode=none → 50 passed (13 VCR tests: 9 chat including GENERIC/Cohere streaming and event mode with and without content, 2 embeddings, 2 rerank; 3 mocked generate_text; unit tests for the finish-reason map, usage normalisation, GENERIC / Cohere v1 / Cohere v2 message conversion with tools, images and reasoning, dedicated serving mode, content gating, the stream accumulator on recorded event shapes, the stream wrapper callback and error path, instrumentor lifecycle, suppression keys, ServiceError and mid-stream error status/metrics). ruff check clean; nx run opentelemetry-instrumentation-oci-genai:lint and :test pass. traceloop-sdk: uv lock && uv sync --all-groups, tests/test_sdk_initialization.py 28 passed; init_oci_genai_instrumentor() returns True with oci installed and wraps GenerativeAiInferenceClient.chat, False without it.
Cassettes scrub the request signature (authorization), opc-request-id, opc-client-info, x-content-sha256, date, user-agent, and every OCID in bodies (ocid1.<type>.oc1..redacted); playback uses a security-token signer with a throwaway key. One thing reviewers should know: the OCI SDK's OCIConnectionPool sets its own ConnectionCls, which bypasses VCR's urllib3 patch, so tests/conftest.py adds a custom_patches entry for it; without that, "recorded" runs silently hit the live API.
Notes: traceloop-sdk/uv.lock also bumps the editable workspace packages 0.62.1 → 0.62.3 because the upstream lock was stale; CI's uv sync would produce the same. No packages/sample-app example and no entry on the Traceloop docs site (separate repo) yet.
I have added tests that cover my changes.
If adding a new instrumentation or changing an existing one, I've added screenshots from some observability platform showing the change.

- Run request handling, the SDK call and synchronous response handling
under use_span(span, end_on_exit=False) so emitted GenAI events carry
the client span's trace context and spans created inside the SDK call
become children instead of siblings. The span is reactivated while the
SSE stream is read (never across a yield) and in _finish_streaming_span
before response events and metrics are recorded.
- OCIGenAIStreamWrapper: GeneratorExit and other BaseExceptions finish
the span as incomplete (status left UNSET, partial output kept), close()
closes the wrapped SSEClient and finishes the span, and only a stream
consumed to the end is marked OK. on_done now receives a complete flag.
- README: alt text on the PyPI badge.
- tests: restore TRACELOOP_TRACE_CONTENT through monkeypatch instead of
deleting it; add span-context correlation and stream lifecycle tests.
When the caller leaves the events() loop early (GeneratorExit, or any
other BaseException), OCIGenAIStreamWrapper now closes the wrapped
SSEClient after finishing the span as incomplete, instead of leaving the
HTTP event source open until garbage collection. The close is
best-effort: a failure is logged at debug level and never masks the
exception being propagated. A later explicit close() by the caller stays
safe, since requests/urllib3 treat a second close as a no-op.
Tests assert the fake event source is closed on early exit (wrapper unit
test and instrumented-client test) and that a failing close() does not
raise or double-report the stream.
Rebased onto main at e3d651a (new head b2dd858). The only conflict was packages/traceloop-sdk/uv.lock (sibling version pins); took main's copy and regenerated it with uv lock. Bumped the new package to 0.63.0 so it matches the .cz.toml version it is registered under.
opentelemetry-instrumentation-oci-genai: 57 tests pass against the recorded cassettes with network blocked (--record-mode=none --block-network); ruff check is clean for the package and for traceloop-sdk.

Include the test group in the test command.
On a fresh environment, uv run pytest tests/ installs the dev group but not this group. Test collection then fails because tests/conftest.py imports oci. Include test in the default groups or pass --group test in the test target. (docs.astral.sh)
