Ntopng export flows1/4/2023 ![]() ![]() The sFlow messaging system is similar to NetFlow in that it creates a format for notifications that are generated by networking equipment and can be picked up by monitoring software. The ethos behind this administration aims to break the dominance of one network equipment supplier and create a universal standard - NetFlow is owned by Cisco Systems. ![]() NTOPNG EXPORT FLOWS SOFTWAREThe sFlow network messaging standard is managed and developed by an independent not-for-profit organization that is overseen by a number of network equipment and software producers. When your organization relies on and develops a complex high-performance network, you need more powerful help. NTOPNG EXPORT FLOWS FREEWhen your organization’s network is behaving strangely, how do you know what’s going on inside it? If you have just a few segments connected by a handful of switches or routers – like a simple small-office/home-office (SOHO) network – you might be fine with basic network monitoring tools, such as the simpler ones from among our lists of the best packet sniffers and network analyzers and best free bandwidth monitoring software. Using sFlow for network traffic monitoring A key characteristic of sFlow is that the strategy of sampling is scalable to high-speed networks more on that below. There is thus no flow cache at the device. It gathers the initial bytes of all sampled packet into sFlow datagrams, along with device counters, and sends the resulting UDP datagrams to the collector. The exporter samples one out of every n packets, where “n” is the chosen sampling rate it also selects some random packets to include. An sFlow exporter simply collects the prefixes of a subset of the packets passing through the device. sFlow provides general-purpose packet sampling, spanning Layers 2 through 7, and is designed to be built into any network device. Today, many vendors support sFlow in their devices. InMon handed over the management of the standard to an industry consortium, called in 2003. The sFlow standard was created by InMon Corporation and was made public in 2001 through the publication of RFC 3176. Available for online access or on-premises installation.

The “s” in the name is significant: sampling. SFlow is a stateless packet sampling protocol that’s aimed at monitoring high-speed networks. ![]()
