sFlow monitoring
sFlow is a standard for monitoring high-speed switched and routed networks. sFlow
technology is built into the switch and many other network devices to give visibility into
network activity.
The sFlow monitoring system consists of an embedded sFlow agent and a central sFlow
collector, also referred to as an sFlow receiver. The sFlow agent uses sampling
technology to capture traffic statistics from the device it is monitoring. sFlow datagrams
are used to forward the sampled traffic statistics to an sFlow collector for analysis.
The sFlow agent uses two forms of sampling: statistical packet-based sampling of
switched or routed packet flows, and time-based sampling of counters.
