Sflow Analyzer Open Source !full!
If you are analyzing 10Gbps or 100Gbps links, the volume of sFlow packets arriving at the analyzer will be immense.
sFlow (Sampled Flow) is a stateless packet sampling protocol (RFC 3176) that exports packet headers and interface counters. Unlike NetFlow/IPFIX, sFlow samples packets at line rate in hardware , making it ideal for high-speed networks (10G–400G). Open-source analyzers vary in architecture (stream processing, databases, time-series) and use cases (security, QoS, capacity planning). sflow analyzer open source
Because sFlow is sampled (e.g., 1-in-1000), it provides a statistical estimate, not an absolute count. An analyzer must be configured to understand this. Small flows (like a single ping) might be missed entirely if they don't hit the sampling bucket. Open-source analyzers often allow adjustment of the "scaling factor" to compensate for this in visualization. If you are analyzing 10Gbps or 100Gbps links,
