Thanks for your prompt answer. It seems the collector see all the network traffic. If it can help, I was a problem : my sflow sampling rate was 8192 and ntop were showing me nothing. On an advice of this mailing list, I modified
plugins/sflowPlugin.c: myGlobals.device[deviceId].samplingRate = sample->meanSkipCount; and put plugins/sflowPlugin.c: myGlobals.device[deviceId].samplingRate = 0; Since this modification, ntop seems to work and the sampling rate is now 1. But I did NOT understand what this change can modify... Maybe this disturbe the calcul of the traffic ?
