How to add a netflow only device

How to add a netflow only device

Hi guys,

I have configured a device to send netflow to manageengine, when i go into my Inventory/devices, I don't see the IP address there, if I go to inventory/interfaces I see about 10 interfaces with this device ip address (none of them have any values received) I deleted them and they all came back immediately.

What are the steps to correctly add the device (just for netflow not for ncm)? if I do a ncm discovery on the hostname, it doesn't let me add the device, it says already present in inventory. 


thanks!
