I am trying to monitor traffic on local network interface (P2_LAN_7).
PRTG probe is placed on computer running Win 10 inside this LAN - 192.168.7.221 (collector).
Mikrotik IP 192.168.7.254 (sender).

result on sensor "No data since startup"

i have also tried the Netflow collector tester (on the same pc) but I am still not getting any data.

Is there a chance that Mikrotik itself is blocking data being sent to LAN 192.168.7.X ?


• /ip traffic-flow set
• interfaces=P2_LAN_7
• cache-entries=2k
• active-flow-timeout=30m ((timeout on sensor is set to 31m according recommendations))
• inactive-flow-timeout=15s
• enabled=yes


• /iptraffic-flowtarget
• add disabled=no
• dst-address=192.168.7.221
• port=1234
• src-address=0.0.0.0
• v9-template-refresh=20
• v9-template-timeout=30m
• version=ipfix

Did you try to actually put something in the "Source Address" in the target config ?
So in stead of 0.0.0.0 put 192.168.7.254 or whatever the IP on the MT side.

I'm using Netflow to (towards Splunk) and this just works.

Sure, Splunk is free upto 500MBytes per day
Now remember Netflow does not just work "out of the box" , you need an App for that (Splunk Stream) (so no "click-click-click ready)
And there is no set of nice details dashboard on Netflow, you need to create that yourself based in the data that is in the database.
