With Netflow how to retrieve assigned protocol name in top connections



We use netflow with success to monitor activities. I can define a protocol name based on IP or/and port used. We use also API to export information to powerbi We export top talkers & top protocol.

But I cannot associate the 2, never in top protocol I have an info saying this transaction is of type protocol A

an example

the filter created for top protocol in netflow

Protocol[TCP] and ( SourcePort[80] or DestinationPort[80])  and  ip[]
Protocol[TCP] and ( SourcePort[81] or DestinationPort[81])  and  ip[]
Protocol[TCP] and ( SourcePort[80] or DestinationPort[80]) 

Now in my top connections , I would like to retrieve the associate protocol directly or via an API (I names my column my wish)

Source IPDestination IPSourcePortMY WISH

I hope someone can help me

api netflow protocol--connections

Hi there,

did you already tried to create a custom toplist in your Sensor? If this don't solves your issue, it's not possible via the native PRTG API.

Thanks a lot, in the custom toplist, there is a field channel, giving the name of the type of traffic. The info I was looking for
