IF a host has only the DNS-Name as Agent interfaces,
and you want use "net.if.in[

{IPADDRESS},bytes]" it doesn work.

but if you enter the IP adress under Agent interfaces it works fine...

pleas add resolving IP-Adress over the DNS-NAME for the Makro Agent {IPADDRESS}

it would be a nice feature, and you can template this item exable for windows hosts whit diferent interface names.
