Instrument LLM Apps with Phoenix Tracing

The Arize-Phoenix LlamaPack provides a workflow integration between LlamaIndex query engines and Arize Phoenix, an observability and evaluation platform for LLM applications. This pack enables developers to instrument their LlamaIndex query pipelines with Phoenix's tracing and monitoring capabilities, allowing them to track query execution, analyze performance, and debug issues in their retrieval-augmented generation (RAG) systems.

Use this pack when you are building production LlamaIndex applications that require observability, performance monitoring, or debugging capabilities for your query engines. It is particularly valuable when you need to trace multi-step retrieval workflows, identify bottlenecks in your RAG pipeline, or evaluate the quality of retrieved context and generated responses. Do not use this pack if you are building simple proof-of-concept applications where observability overhead is unnecessary, or if you are already using a different observability solution that conflicts with Arize Phoenix's instrumentation approach.
