About:
nfdump is a powerful toolset designed to collect and process netflow data on the command-line. It reads data from flow tools like nfcapd and allows users to filter, aggregate, and analyze network traffic efficiently. Its main value proposition is providing high-performance analysis capabilities for large volumes of flow data.
Key Features:
  • High-performance reading and writing of flow data
  • Flexible filtering and aggregation syntax
  • Support for multiple flow versions (NetFlow v1, v5, v7, v9, IPFIX)
  • Integration with tools like nfcapd for continuous collection
Use Cases:
  • Network traffic analysis and monitoring
  • Security incident response and forensics
  • Capacity planning and usage billing
Alternatives:
  • pmacct – pmacct offers similar network monitoring capabilities but often focuses more on BGP and IP accounting integration.
  • ntopng – ntopng provides a web-based GUI for traffic analysis, whereas nfdump is primarily command-line driven.
