LlamaIndex Workflows Tracing

LlamaIndex Workflows are a subset of the LlamaIndex package specifically designed to support agent development.

Install#

pip install openinference-instrumentation-llama_index

Setup#

Initialize the LlamaIndexInstrumentor before your application code. This instrumentor will trace both LlamaIndex Workflows calls, as well as calls to the general LlamaIndex package.

from openinference.instrumentation.llama_index import LlamaIndexInstrumentorfrom phoenix.otel import registertracer_provider = register()LlamaIndexInstrumentor().instrument(tracer_provider=tracer_provider)

Run LlamaIndex Workflows#

By instrumenting LlamaIndex, spans will be created whenever an agent is invoked and will be sent to the Phoenix server for collection.

Observe#

Now that you have tracing setup, all invocations of chains will be streamed to your running Phoenix for observability and evaluation.
