Missing Metric documentation #4222
Description
There are metrics gen_ai_chat_client.operation_* for the chat client and db_vector_client_operation_* for the vector database. Legend: *=count,max,sum. However, I can't find any documentation on this in the current documentation under Observability. What do the metric values mean? Especially the distinction between gen_ai_chat_client.operation_active_* and no active gen_ai_chat_client.operation_* in both cases chat and vector.
