Which of the following can be used to monitor bandwidth usage and traffic patterns across devices?

NetFlow provides flow-based telemetry that reveals how much bandwidth is being used and what traffic patterns look like across devices. It captures flow records that include source and destination IPs, ports, protocol, bytes, packets, and duration, then exports these to a central collector. By analyzing these flow records, you can quantify bandwidth usage on each interface, identify top talkers and dominant applications, and spot unusual patterns or bottlenecks over time. This cross-device visibility is what makes NetFlow the best choice for monitoring both bandwidth and traffic patterns. Ping monitoring only checks reachability and latency, not usage. SNMP can give interface counters but doesn’t provide detailed per-flow traffic patterns without additional tooling. DNS monitoring focuses on name resolution performance, not bandwidth.
