[Observium] Both HOSTNAME and IP ADDRESS in Observium

Hello all,

I am new to Observium, i am wondering if it is possible to have both the 'hostname' and 'IP address' of our monitored devices in 'devices' -> 'All Devices' tap?

Actually i can either add a device by :

1) Its IP address thus i won't have the 'hostname'

2) Or add the 'hostname" and 'IP address' in (/etc/hosts) and add the equipment on Observium, with this option i won't have the IP address
