Prtg sFlow Sensor only certain traffic.



I see that I can add a sFlow sensor including interfaces and excluding interfaces. Can I only report certain traffic from a interface? I have a switch port that feeds into the vendor managed router. This switch port is for our WAN network and internet network. I would like to separate the sFlow information to watch for the network between the branches from the sFlow information that is for internet.

I already have a sFlow sensor for the interface.

Hi Edward,

You need to use the custom version of the sensor and create your own filter rules to show traffic for particular IP-Addresses only. You can find the filter rules here.

Kind regards,
