Python autoinstrumentation library for the Anthropic package. This package implements the following Anthropic clients:
  • Messages
  • Completions
  • AsyncMessages
  • AsyncCompletions
These traces are fully OpenTelemetry compatible and can be sent to an OpenTelemetry collector for viewing, such as Arize Phoenix.

​
Installation

pip install openinference-instrumentation-anthropic

​
Quickstart

Install required packages: 
pip install openinference-instrumentation-anthropic anthropic arize-phoenix opentelemetry-sdk opentelemetry-exporter-otlp

​
Start Phoenix server

python -m phoenix.server.main serve
By default, Phoenix listens on http://localhost:6006. You can visit the app via a browser at the same address. (Phoenix does not send data over the internet. It only operates locally on your machine.)

​
Setup instrumentation

Set up AnthropicInstrumentor to trace your application and send traces to Phoenix: 
import os
from anthropic import Anthropic
from openinference.instrumentation.anthropic import AnthropicInstrumentor
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk import trace as trace_sdk
from opentelemetry.sdk.trace.export import SimpleSpanProcessor

# Configure AnthropicInstrumentor with Phoenix endpoint
endpoint = "http://127.0.0.1:6006/v1/traces"
tracer_provider = trace_sdk.TracerProvider()
tracer_provider.add_span_processor(SimpleSpanProcessor(OTLPSpanExporter(endpoint)))

AnthropicInstrumentor().instrument(tracer_provider=tracer_provider)

os.environ["ANTHROPIC_API_KEY"] = "YOUR_KEY_HERE"

client = Anthropic()

response = client.messages.create(
    max_tokens=1024,
    messages=[
        {
            "role": "user",
            "content": "Tell me about the history of Iceland!",
        }
    ],
    model="claude-3-opus-20240229",
)
print(response)
Now, on the Phoenix UI in your browser, you should see the traces from your Anthropic application. Click on a trace, then the “Attributes” tab will provide you with in-depth information regarding execution.
