Dear Tristan

thanks, i know about that. however i was asking for workaround, because once the device is located in the /etc/hosts file, then i do not need to discover it ( in a certain sense ) , cause it is known :-).
The point is that i have a hundreds of Cisco AP's and dozen of switches all around the world, that i do not now about their IP's and particular location..
They all have CDP running so i would have to first log to those switches and check their names,neighbors,  relations and so on. And this i would like to avoid. Different departments configure devices and not all of them are known ( we operate in 60 countries ).

So is there a way to discover them without being known by the DNS or hosts file ? ( there is a netdisco tool, that can manage it , however i prefer Observium cause it is more powerful )

Many Thanks
Pet .

Pet, 

The wiki you linked to has the solution:

Alternative: Add lines to the "/etc/hosts" file on Observium that match the hostnames and domains that you have configured in your devices.

Hi
I've started you use Observium mand must say I'm very impressed :-). Very useful and comfortable tool

I have question regarding the autodiscovery feature. I read the do here , http://www.observium.org/wiki/Device_Autodiscovery, and one of the condition is that sysName and device name must be same, or resolvable.
In our scalable design all over the world it is very difficult, cause there are about 80 domains and strong of the domain itself takes about 20 characters, so we use only hostname resolvable via /etc/hosts. We also cannot use DNS, cause AD DNS is processed by the other department ( in Asia :-) , and it would take a weeks to synchronize it.

So the question is, how can i workaround the auto discovery without same sysName and the hostname ? As far as get it, sysName only  contains the domain extension of the hostname.
we have about 300 routers/switches, so we want to discover them automatically.

many thanks
