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
