if you have a list of the hostnames the easiest way would be to just use add_device.php and feed it a textfile of all your servers.

Otherwise you could use LLDP-discovery for example if all your servers are talking LLDP to the switches and you already have the switches in Observium.

now question is how to add those 1000 device? Does Observium has any
kind of auto discovery and add device itself?
