We released another free utility yesterday called Flowalyzer. The Flowalyzer NetFlow & sFlow Tester is a free NetFlow and sFlow Tool Kit for testing and configuring hardware and software.

Flowalyzer can help you troubleshoot hardware from vendors like Cisco and Enterasys, as well as testing the NetFlow collector software, to ensure that both the hardware and software are configured correctly.

The Flowalyzer provides the following functions::

  • Listener
  • Generator
  • Configurator
  • Communicator


The Listener application can determine which flow exporting device(s) are sending the highest volume; can listen on multiple ports; display the packet count, version of NetFlow, and the UDP port that flows are coming in on; and also displays the IP address and DNS name.

The Generator application can generate NetFlow v5 and v9 flow packets to test your NetFlow collector application. You can test that your collector is accepting flows and also whether or not it is dropping flows by comparing what is sent from Flowalyzer to what is received by your collector.

You can use the Configurator application as a configuration wizard to configure Cisco Routers or Enterasys switches for exporting NetFlow data. The Configurator uses SNMP to make OID sets, supporting SNMP v1, v2, and v3.

This application gives you the ability to run a ping or a traceroute to any host with the communication responses in a very clear, highly readable response display. You can select to ping via ICMP, UDP, or TCP protocols.
