sFlow monitoring is a network monitoring technology used to capture and analyze traffic data in real-time. It operates by sampling packets flowing through network devices, such as switches and routers, to provide insights into network traffic patterns and performance. Unlike traditional methods that inspect every packet, sFlow uses statistical sampling to efficiently monitor network traffic without overwhelming the monitoring system.
It collects key information about network traffic, including source and destination IP addresses, protocols, and traffic volumes, enabling network administrators to identify anomalies, troubleshoot issues, and optimize network performance. sFlow is widely used in large-scale networks for its scalability and low overhead.
