We are having an installation with over 1000 switches, and several persons are installing new switches every week. So, just to be able to know where and to what switch a new device is connected is impossible.
DNS is in our case auto-generated, BUT, we are allowing additions in the hostname after the standard first 8 characters in the name/dns-entry.
But, we solved it: discovery.php -d -h all | grep "autodiscovery fails" >/opt/observium/logs/discovery.log
From that file a can see what switches that not is added through autodiscovery.
”discovery fails” comes from the rows in the discovery process: Example: o Try discovering host swe10011-otherthings through CDP Host swe10011-otherthings not resolved, autodiscovery fails.
I hope this can help others witch the same problem.

Fromt the CLI run this: ./discovery.php -d -m neighbours -h <device-you-want-to-start-discovery-from>
this will run the discovery module on a device, look for neighours and the try to add the discovered neighbours to observium, -d will add debug output

Hello! I know that many of my new devices doesnt have the same DNS and hostname, so, autodiscovery is not working. Is there a way to debug this so I know what switches isn’t autodiscovered?
