OpenInference Google GenAI Instrumentation

Python auto-instrumentation library for GenAI SDK. Traces are fully OpenTelemetry compatible and can be sent to any OpenTelemetry collector for viewing, such as Arize Phoenix or Arize AX.

Installation

pip install -Uqqq openinference-instrumentation-google-genai

Quickstart

Install openinference-instrumentation-google-genai and arize-phoenix.

pip install -U \
    openinference-instrumentation-google-genai \
    arize-phoenix \
    opentelemetry-sdk \
    opentelemetry-exporter-otlp \
    "opentelemetry-proto>=1.12.0"

Start the phoenix server so that it is ready to receive traces. The phoenix server runs entirely on your machine and does not send data over the internet.

phoenix serve

Instrumenting genai is simple.

from openinference.instrumentation.google_genai import GoogleGenAIInstrumentor
from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import SimpleSpanProcessor

endpoint = "http://127.0.0.1:4317"
tracer_provider = TracerProvider()
tracer_provider.add_span_processor(SimpleSpanProcessor(OTLPSpanExporter(endpoint)))

GoogleGenAIInstrumentor().instrument(tracer_provider=tracer_provider)

Now, all calls by generate_content are instrumented and can be viewed in the phoenix UI.

Progress

This instrumentation is a work in progress

  • parse messages and invocation
  • capture tool definitions
