[Feature Request] Add Observability tool like Langfuse

[vkehfdl1]

@Aaryaveerkrishna23

I would like to know how we can add a layer of observability in auto RAG, such as using Langfuse, for example, to monitor the system in development, pre-production, and production environments , to check what chunks are being retrieved , what was the final prompt after data augmentation etc .

Great idea!
