sflow/sflowtool repository overview

⁠What is sflowtool?

sflowtool⁠ receives sFlow data, and generates either a simple-to-parse tagged-ASCII output, or binary output in tcpdump(1) format. It can also generate Cisco NetFlow version 5 datagrams and send them to a destination UDP host:port, or forward the original sFlow feed to a number of additional collectors.
