renetcol ( RENATER  NetFlow Collector) is a NetFlow collector under GPL. NetFlow is a technology originally proposed by  Cisco, that is currently under standardization in  IPFIX IETF working group. renetcol works with NetFlow Data Export version 9, which allows to monitor IPv6, Multicast and MPLS flows, in addition to the IPv4 ones. The main functionnalities of renetcol are:

  • Real-time flow monitoring (tcpdump-like)
  • RRD accounting for IPv4 subnet
  • RRD accounting for BGP AS number
  • RRD accounting for IPv6 links (new in release 0.0.14beta)

Roadmap

  • RRD accounting for IPv6 subnet
  • Top AS

renetcol in production

  • On RENATER backbone (since 2007):
    • NetFlow configured in full mode on 22 Cisco 7600, 14 Cisco 7200.
    • NetFlow configured in sampled mode (1 packet / 10) on 3 Cisco CRS-1, 7 Cisco 12400 (IOS-XR) and 6 Cisco 12400 (IOS)
    • NetFlow Data Export (NDE) trafic until 80 Mbits/s on the collector.
    • Aggregation & accounting for 3800 IPv4 prefixes, 376 BGP AS & all links where we have IPv6.
    • Real-time flow monitoring for  CERT RENATER
    • hardware monitoring
