NetFlow is a network protocol that provides key traffic flow data, enabling administrators to understand bandwidth utilization and identify network bottlenecks, unlike SNMP, which offers broader network-device telemetry. Datadog has introduced NetFlow monitoring through its Network Device Monitoring (NDM) view, allowing users to visualize NetFlow data and variants like IPFIX and sFlow within the platform. This feature helps organizations identify top network traffic contributors, optimize resource utilization, and plan for capacity upgrades. By visualizing critical data on a customizable dashboard, administrators can monitor the state of their network, address congestion, and prioritize essential applications to ensure smooth operations. With the integration of NetFlow monitoring, Datadog users can diagnose network issues alongside SNMP Trap data, aiding in troubleshooting and network health management.
