Datadog's Cloud Network Monitoring (CNM) feature provides comprehensive visibility into network and DNS performance, enabling users to quickly spot issues that manifest as traffic spikes, drops, or latency between different endpoints in their environment. CNM automatically collects key transport-layer (TCP/UDP) and DNS data related to traffic between each endpoint, including VMs, containers, services, cloud regions or datacenters, and much more. The feature provides an out-of-the-box CNM Overview dashboard that organizes network metrics into essential categories, such as Network load, TCP metrics, DNS metrics, Application overview, and Cross-regional traffic metrics. These metrics provide a unified view of key network health and performance across different facets of the distributed network. Additionally, CNM enables users to quickly monitor critical dependencies with Saved Views, which provide quick access to relevant network flow data. The feature also correlates network data with telemetry from each layer of the stack, enabling users to pinpoint root causes of issues. Overall, Datadog's Cloud Network Monitoring helps make troubleshooting problems with your network easier by providing a comprehensive and unified view of key network performance metrics.
