nfdump is a toolset in order to collect and process netflow/ipfix and sflow data
sent from netflow/sflow compatible devices.
The toolset contains several collectors to collect flow data:
- nfcapd supports netflow v1, v5/v7,v9 and IPFIX
- sfcapd support sflow
- nfpcapd converts pcap data read from a host interface or from pcap files.
nfdump is now a multi-threaded program and uses parallel threads mainly for reading,
writing and processing flows as well as for sorting.
