For some reason, my PRTG is not classifying certain traffic into the channel defined. As a result, they are in the default "Other" Channel. For testing, I created a NetFlow v9 Customer sensor,with only one channel:
#70 VoIP_Down DestinationIP[172.28.11.0/24]
When debugging the stream data log, I can see the flow information such as:
Now,FromDateTime,ToDateTime,EthernetType,Protocol,SourceIP,SourcePort,SourceMAC,DestinationIP,DestinationPort,DestinationMAC,Size,ChannelID,ToS,SenderIP,InboundInterface,OutboundInterface,SourceASI,DestinationASI,SourceMask,DestinationMask,NextHop,SourceVLAN,DestinationVLAN 7/09/2012 9:51:06 PM,7/09/2012 11:50:47 AM,7/09/2012 11:50:47 AM,0,17,172.28.11.3,123,00-00-00-00-00-00,220.127.116.11,123,00-00-00-00-00-00,76,0,0,18.104.22.168,40,31,0,0,24,0,22.214.171.124,0,0 7/09/2012 9:51:06 PM,7/09/2012 11:50:47 AM,7/09/2012 11:50:47 AM,0,17,126.96.36.199,123,00-00-00-00-00-00,172.28.11.3,123,00-00-00-00-00-00,76,0,16,188.8.131.52,31,40,0,0,0,24,172.28.11.3,0,0
However the channel "VoIP_Down" doesn't show up in the graph or the channel list. My PRTG version is PRTG Network Monitor 184.108.40.20654
I also tried channel with "DestinationIP[172.28.11.*]" and still falls into "Other" Can someone help to see why?
