Collects OpenTelemetry traces from all services, correlating spans by trace ID so any request can be followed end-to-end across the full call chain. Stores traces for 30 days with sub-second query response for recent data. Used as the primary tool for diagnosing latency regressions, cascading failures, and unexpected service interactions in production.
