OpenInference Google VertexAI Instrumentation

Python auto-instrumentation library for VertexAI SDK and the Google Cloud AI Platform. Traces are fully OpenTelemetry compatible and can be sent to any OpenTelemetry collector for viewing, such as Arize Phoenix.

pypi

Installation

pip install -Uqqq openinference-instrumentation-vertexai

Quickstart

Install openinference-instrumentation-vertexai and arize-phoenix.

pip install -U \
    openinference-instrumentation-vertexai \
    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.

python -m phoenix.server.main serve

Instrumenting vertexai is simple.

from openinference.instrumentation.vertexai import VertexAIInstrumentor
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)))

VertexAIInstrumentor().instrument(tracer_provider=tracer_provider)

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

import vertexai
from vertexai.generative_models import GenerativeModel

vertexai.init(location="us-central1")
model = GenerativeModel("gemini-1.5-flash")

print(model.generate_content("Why is sky blue?"))
