Google GenAI

Use the GoogleGenAiSdkInstrumentor from opentelemetry-instrumentation-google-genai to auto-instrument the Google GenAI SDK. Traces are exported to a local OpenTelemetry Collector over OTLP/gRPC; the collector forwards to Coralogix.

Before you start

These examples export to a local OpenTelemetry Collector over OTLP/gRPC. Deploy the collector first — see Code examples → Deploy an OpenTelemetry Collector.

Install

pip install google-genai opentelemetry-instrumentation-google-genai opentelemetry-sdk opentelemetry-exporter-otlp-proto-grpc

Environment variables

export GOOGLE_API_KEY="<YOUR_GOOGLE_API_KEY>"
# Point to your local OTel Collector (which forwards to Coralogix)
export OTEL_EXPORTER_OTLP_ENDPOINT="http://<COLLECTOR_HOST>:4317"
export OTEL_EXPORTER_OTLP_INSECURE="true"
export OTEL_SEMCONV_STABILITY_OPT_IN="gen_ai_latest_experimental"
export OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT="SPAN_AND_EVENT"

    )
    print(f"Gemini response: {response.text}")

    # OTel: flush and shut down the tracer provider
    provider.force_flush()
    provider.shutdown()


if __name__ == "__main__":
    main()

Expected span attributes

• gen_ai.provider.name = "google_genai"
• gen_ai.request.model = "gemini-2.0-flash"
• gen_ai.operation.name = "chat"
• gen_ai.usage.input_tokens, gen_ai.usage.output_tokens
• gen_ai.input.messages, gen_ai.output.messages (with content capture)

Tip

Put your Coralogix Send-Your-Data API key on the collector (e.g. CORALOGIX_PRIVATE_KEY in otel-collector-config.yaml), not in the Python exporter. The exporter only needs to reach the local collector.

Next steps

Look up which open-source library to use for your provider in Compatibility matrix.
