Description
One of the best features of Observium is automatic discovery by spidering a network using CDP/LLDP. However, the current implementation will only add a device if the discovered hostname matches a usable DNS name (or local hosts file).
The web-interface needs a way to show admins which devices were identified during discovery, but then failed to be added for some reason. This information may already exist in the "Links" table.
With this information, admins can correct the the problem and Observium will discover the fixed devices during the next discovery.

This is exacly what I am looing for, any progress on this?
To be able to see if devices fail autodiscovery due to hostname not being resolvable or wrong SNMP community would be great(also to display the IP address)
Under ports, neighbours I can filter on unknown devices but can't see the actual IP adress without logging into the local device and doing a "show....cdp/lldp details"
Keep up the good work

Where is this information found on the web-interface? I am running Observium 0.15.2.6240.
I did find a temporary work-around to get this information:
1) Perform a debug discovery and save the output to a file > "output.log"
2) Search that log for "autodiscovery fails".
grep "autodiscovery fails" output.log
This will give you the hostnames of the devices that failed discovery, perhaps because:
"Host AVX5BE9F3 not resolved, autodiscovery fails."
Actually, this will not help in many cases when the admin doesn't know the IP of that hostname. Observium needs to tell admins the "Management IP" that was gathered from xDP.
Fixed in recent (rolling) versions.
