 ### Traces
 
-- A trace represents a single transaction or request through your system. This includes things like user browser sessions, HTTP requests, DB queries, middleware, caches and more.
-- It captures a series of operations (_spans_) that show how different parts of your application interacted during that transaction.

 ### Span Metrics
 
-- [Span metrics](/concepts/key-terms/tracing/span-metrics/) are derived from applying a function to your span attributes (default or custom), like `p50(cart.value)` or `sum(ai.token_use)`, over a granular time frame. This calculation extrapolates metrics that then populate dashboards, alerts, etc. based on that rolling time window.
