Monitor application performance with Distributed Tracing

This post announces the Beta release of Distributed Tracing as a new feature within GitLab Observability. It explains what distributed tracing is, how it works (collecting data with OpenTelemetry, ingesting/retaining with ClickHouse/Kubernetes, and analyzing via a new UI), and provides two internal use cases: debugging the GitLab Agent for Kubernetes and optimizing build pipeline duration. It also highlights the integration with OpenTelemetry as a vendor-neutral approach and mentions the underlying storage solution based on the Opstrace acquisition.
