Ok, you can fix that by adding the right domain to your config.
for Cisco switches that is:
ip domain yourdomain.com

this will make the switch report its FQDN via CDP so that it will be "swe10011-otherthings.yourdomain.com" and if you autogenerate DNS for that Observium will be able to resolv it and add the switch via autodiscovery.

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.

 

Regards

Fredrik

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?

 

 

Regards

Fredrik
