 Traces link together related transactions to show an end-to-end performance of how a request was served and which services were part of it. In addition to the Traces overview, you can view your application traces in the [trace sample timeline waterfall](/solutions/observability/apm/trace-sample-timeline.md).

 A trace is a group of [transactions](/solutions/observability/apm/transactions.md) and [spans](/solutions/observability/apm/spans.md) with a common root. Each trace tracks the entirety of a single request. It describes the individual operations and their causality that ensue from a single logical operation.

The chat interface translates your natural language questions into {{es}} queries, retrieves the most relevant results from your {{es}} documents, and passes those documents to the LLM to generate tailored responses.
