The text discusses the implementation of a dual-approach monitoring system called Network Inspector in CockroachDB Cloud, which improves network observability and enables proactive detection and resolution of network issues before they affect customers. The solution combines two complementary approaches: proactive network probes that monitor DNS health and pod-to-pod connectivity, and network observation via Hubble, which enriches network metrics with contextual labels. By providing real-time visibility into network health, Network Inspector helps detect issues earlier and provides the detailed metrics needed for quick problem resolution.
