Prompt Flow Tracing

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

Prompt flow exports to the endpoint as given, so it must be the full OTLP traces URL — including the /v1/traces path:

PHOENIX_COLLECTOR_ENDPOINT=http://localhost:6006/v1/traces

import osfrom opentelemetry.sdk.environment_variables import OTEL_EXPORTER_OTLP_ENDPOINTfrom promptflow.tracing._start_trace import setup_exporter_from_environendpoint = os.environ.get(    "PHOENIX_COLLECTOR_ENDPOINT", "http://localhost:6006/v1/traces")os.environ[OTEL_EXPORTER_OTLP_ENDPOINT] = endpointsetup_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.
