+
+LocalAI can retain recent API exchanges and backend operations for inspection
+on the **Traces** page in the management interface. Enable tracing in runtime
+settings or with the existing tracing configuration.
+
+API and backend trace histories are persisted in separate directories below
+the configured data path. They are restored after a clean service restart,
+whether or not authentication is enabled.
+
+Each history remains independently bounded by `tracing_max_items`. When a
+history reaches that limit, LocalAI removes its oldest records from memory and
+disk. The existing clear actions on the Traces page remove both the in-memory
+history and its persisted records.
