1. What is sFlow? sFlow (Sampled Flow) is an industry-standard technology for monitoring network traffic. Unlike full packet capture tools (like tcpdump) or flow aggregation protocols (like NetFlow), sFlow uses statistical sampling to monitor all traffic at wire speed without impacting performance.
