To whom it may concern,
Currently we are having some issues with Observium's Auto Discovery. The problem is that it currently only discovers about 10% of the network. Does somebody have a clue on how to fix this issue? We already disabled the option "require valid hostnames" at the auto discovery settings.
Unfortunately after changing this option, it only discovered about 10 more devices. Also we do not have any problems with the CDP neighbours on our switches.
Best regards, Mikey van der Worp

I had issues getting the auto discovery working too, although I managed it in the end! These are the entries in my config.php for auto discovery:
//Autodiscovery $config['mydomain'] = "myswitchdomain.co.uk"; $config['autodiscovery']['ip_nets'] = array("10.0.23.0/23", "10.0.28.0/23", "10.0.17.0/23", "10.0.3.0/23", "10.0.50.0/23", "10.0.52.0/23", "10.0.54.0/23", "10.0.13.3/32"); $config['autodiscovery']['xdp'] = TRUE; // Autodiscover hosts via discovery protocols $config['autodiscovery']['ospf'] = TRUE; // Autodiscover hosts via OSPF $config['autodiscovery']['bgp'] = TRUE; // Autodiscover hosts via iBGP $config['autodiscovery']['snmpscan'] = TRUE; // autodiscover hosts via SNMP scanning
Hope this helps you!

Hey Mikey, you can troubleshoot the neighbor discovery by manually discover the device you want to start from with debug output like this: ./discovery.php -m neighbours -d -h <switchname>
