flow-tools vs cflowd
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
