 # How to trace your application with prompt flow SDK | Azure Machine Learning
 
+> [!CAUTION]
+> **Deprecation notice:** The prompt flow tracing SDK has been has been deprecated in favor of [tracing with Azure AI Foundry project library](../../ai-foundry/how-to/develop/trace-local-sdk.md). The prompt flow config `set trace.destination` attribute is not supported to send traces to Azure Machine Learning workspaces, use the Azure AI Inference SDK with Azure AI Foundry project library to trace your application code.

 Tracing is a powerful tool that offers developers an in-depth understanding of the execution process of their generative AI applications such as agents, [AutoGen](https://microsoft.github.io/autogen/docs/Use-Cases/agent_chat), and retrieval augmented generation (RAG) use cases. It provides a detailed view of the execution flow, including the inputs and outputs of each node within the application. This essential information proves critical while debugging complex applications or optimizing performance.
