PolarDB for PostgreSQL integrates DAS features into its quick diagnostics. When a cluster shows signs of slowdown, the real-time performance feature gives you an immediate view of what's happening across all nodes — without waiting for scheduled reports. It surfaces QPS, TPS, and network traffic in real time, so you can catch performance issues as they develop and act before they affect your workload.
