DSPy Tracing in Phoenix

Published on May 19, 2024. Updated on

I pop the following instrument_dspy() into my utils library to get tracing in Phoenix from DSPy.

def instrument_dspy():
    """Setup DSPy tracing in phoenix"""
    import phoenix
    import opentelemetry
    import openinference.instrumentation.dspy

    phoenix.launch_app()
    opentelemetry.trace.set_tracer_provider(opentelemetry.sdk.trace.TracerProvider(
        resource=opentelemetry.sdk.resources.Resource(attributes={}),
        active_span_processor=opentelemetry.sdk.trace.export.SimpleSpanProcessor(
            span_exporter=opentelemetry.exporter.otlp.proto.http.trace_exporter.OTLPSpanExporter(
                endpoint=f'{phoenix.active_session().url}v1/traces'))))

    openinference.instrumentation.dspy.DSPyInstrumentor().instrument()
