Why use flow-tools instead of cflowd?

  • flow-capture preserves the sub-second portion of the NetFlow timestamps that cflowd discards
  • flow-tools is easier to build because it is written in portable C. Problems with building cflowd may occur because it requires cutting edge C++ features
  • flow-tools is actively maintained, and supports newer NetFlow versions, including those from the popular Cisco Cat6K series platforms
Using flow-tools only required a small change to FlowScan, so a full release was not done. Tips for configuring FlowScan to work with flow-tools can be found at: http://net.doit.wisc.edu/~plonka/list/flowscan/archive/1117.html.

Does FlowScan still support cflowd?

FlowScan supports cflowd as long as Dave Plonka's patch is installed. Currently, a majority of FlowScan users choose cflowd.
