Prompt Flow Tracing

Create flows using Microsoft PromptFlow and send their traces to Phoenix

This integration will allow you to trace Microsoft PromptFlow flows and send their traces intoarize-phoenix.

Install

pip install promptflow

Setup

Set up the OpenTelemetry endpoint to point to Phoenix and use Prompt flow’s setup_exporter_from_environ to start tracing any further flows and LLM calls.

import os
from opentelemetry.sdk.environment_variables import OTEL_EXPORTER_OTLP_ENDPOINT
from promptflow.tracing._start_trace import setup_exporter_from_environ

endpoint = f"{os.environ["PHOENIX_COLLECTOR_ENDPOINT]}/v1/traces" # replace with your Phoenix endpoint if self-hosting
os.environ[OTEL_EXPORTER_OTLP_ENDPOINT] = endpoint
setup_exporter_from_environ()

Run PromptFlow

Proceed with creating Prompt flow flows as usual. See this example notebook for inspiration.

Observe

You should see the spans render in Phoenix as shown in the below screenshots.
