How to define ethernet card in network maps

[limbooface]

I have point to point setup between 2 10G cards and in my network map I have a link from the server 10G card to the client 10G card. I wish to show the IN and OUT of network traffic

example: IN:{server:ifInOctets[Intel(R) Ethernet Server Adapter X520-2 #2].last(0)}
OUT:{server:ifOutOctets[[Intel(R) Ethernet Server Adapter X520-2 #2].last(0)}

The above is wrong as I am getting IN: *UNKNOWN* OUT: *UNKNOWN*

How should the above be defined? The interface I am getting graphs on is Adapter X520-2 #2

I know how to define network ports on switch but not on network cards.

IN:{servername:net.if.in[Intel(R) Ethernet Server Adapter X520-2 #2].last(0)}
OUT:{servername:net.if.out[Intel(R) Ethernet Server Adapter X520-2 #2].last(0)}

Seems to be working with the above commands
