for CDP/LLDP autodiscovery to work you need this: 1) device address is inside the subnet(s) added in $config['autodiscovery']['ip_nets'] 2) device configured hostname match DNS hostname 3) device domain-name match DNS domain
for exampel if you have a cisco switch with dns address: switch1.mgmt.company.com you need to have this config in the swtich: hostname switch1 ip domain-name mgmt.company.com
Observium will get hostname and domain name via CDP/LLDP and then try to resolve it.
For OSPF/BGP autodiscovery you will also need PTR to match as observium will find a OSPF peer with address 192.168.58.1 and then looks for PTR for that address before it can be added.

Hi all,
My first post here. First I must say that Observium is the most easy looking open source tool I have ever seen J
I’m trying to figure out a few config items that maybe someone can help me with.
*Autodiscovery*
If I’m using $config['autodiscovery']['xdp'] = TRUE; and $config['autodiscovery']['snmpscan'] = TRUE;
First it does not seems to add any devices discovered with LLDP/CDP, nor have I found a way to do a snmpscan based on my subnets (also added)
1.) Does Autodiscover work as the config file says the feature is not yet added?
*PTR/DNS*
Does observium require a PTR record for every device or just a valid host name trough SNMP? How about FQDN?
*WMI *
Seems to be a topic not much covered and not really supported, however in the modules section of a device, let’s say a server one can find an on/off switch for WMI and also a settings page.
Does this mean WMI is somewhat supported or just a GUI glitch?
Thanks
