openNMS fetch nodes from DNS server

Question

I am trying to get openNMS (v1.12) to fetch the list of nodes from DNS server. First, I tried to add requisition-def in my provisiond-configuration.xml with dns://mydnsServerIP/myZone and following, I executed:

/opt/opennms/bin/send-event.pl uei.opennms.org/internal/reloadDaemonConfig --parm 'daemonName Provisiond'

to avoid restarting. Nothing happened.

Following, I tried to add the dns URL in configure discovery URL in the admin page. After saving, discovery.log started having entries like this:

2014-02-24 20:54:53,919 WARN  [OpenNMS.Discovery-Thread] DiscoveryConfigFactory: 
Unknown host '<node building="MYZONE_HERE" foreign-id="520105224"

address ignored

2014-02-24 20:54:53,925 WARN  [OpenNMS.Discovery-Thread] DiscoveryConfigFactory:

2014-02-24 20:54:53,927 WARN  [OpenNMS.Discovery-Thread] DiscoveryConfigFactory:

2014-02-24 20:54:53,929 WARN  [OpenNMS.Discovery-Thread] DiscoveryConfigFactory: 
Unknown host '</node>' inside discovery include file: address ignored

It there anything else I have to do to get it to auto discover nodes from DNS server?

Thanks in advance!

Your OpenNMS server that is initiating the provisioning via a DNS import must be allowed to perform a zone transfer. You can test it with the following from your OpenNMS server console.

dig -t AXFR @<dnsServer> <zone>

If that fails the provisioning will fail.

Also you need to create a provisioning group first.
