The interface through which the packets exited the agent. ![]() The interface through which the packets entered the agent.The sampled data is sent as a UDP packet to the sFlow Collector on port 6343.Each datagram contains the following information: The sFlow agent sends counters and flow samples to the sFlow collector in UDP datagrams. The sFlow agent’s two main function are Random Sampling and Statistics Gathering. Random sampling of packets or application layer operations,Īn sFlow monitoring system consists of an sFlow agent embedded in the switch/router and a centralized collector.sFlow is supported by multiple network device manufacturers and network management software vendors.An sFlow system consists of multiple devices performing two types of sampling: SFlow uses sampling to achieve scalability and therefore is applicable to high speed networks (Gbps and even higher). ![]() ![]() sFlow is designed to be embedded in any network device and to provide continuous statistics on any protocol (up to L7), so that all traffic throughout a network can be precisely monitored. It provides a means for exporting truncated packets, together with interface counters. sFlow packet export at Layer 2 of the OSI model. Originally developed by InMon, sFlow is the leading, multi-vendor, standard for monitoring networks. SFLOW is abbreviation for “ Sampled flow”.
