Change title on graphite graphs

My check_network.exe agent service is using the funky windows interface name and that is what is being fed to carbon/graphite for graphing. So the graphs end up here:
/opt/graphite/storage/whisper/icinga2/$HOSTNAME/services:
Network/network-windows/perfdata
Network/network-windows/perfdata/Intel[R]Ethernet_Connection[2]_I219-V_in
Network/network-windows/perfdata/Intel[R]Ethernet_Connection[2]_I219-V_in/value.wsp
Network/network-windows/perfdata/Intel[R]_I211_Gigabit_Network_Connection_in
Network/network-windows/perfdata/Intel[R]_I211_Gigabit_Network_Connection_in/value.wsp
Network/network-windows/perfdata/Intel[R]_I211_Gigabit_Network_Connection_out
Network/network-windows/perfdata/Intel[R]_I211_Gigabit_Network_Connection_out/value.wsp
Network/network-windows/perfdata/network
Network/network-windows/perfdata/network/value.wsp
Network/network-windows/perfdata/Intel[R]Ethernet_Connection[2]_I219-V_out
Network/network-windows/perfdata/Intel[R]Ethernet_Connection[2]_I219-V_out/value.wsp

Where can I change the name for the interface? Do I do it in director somewhere?

Thanks!
