3.2 Graphing with sFLow and NTOP

I have a running NTOP server listening to sFlow on 192.168.0.18 port 61000 and want to graph network traffic of br0 bridge.

3.2.1 Open vSwitch sFlow configuration

sflow

  • a Select Flows tab
  • b Select sFlow tab
  • c Enter ip and port of distant NTOP server
  • d Validate. A UUID should appear in e !

3.2.2 Visualization in NTOP

With 2 docker containers (10.0.0.2 and 10.0.03) attached to br0, let's generate some traffic on br0 with iperf.

The result can be seen on NTOP interface: sflow

3.2.3 Additional NTOP configuration

Here are some details on how to basically configure NTOP sFlow collector: sflow

  • f Select Configure
  • g Enter listening port for collector
