LlamaIndex Workflows are a subset of the LlamaIndex package specifically designed to support agent development.
Our LlamaIndexInstrumentor automatically captures traces for LlamaIndex Workflows agents. If you’ve already enabled that instrumentor, you do not need to complete the steps below.
We recommend using llama_index >= 0.11.0
Install
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.
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.
