Syslog messages missing nodelabel, location, and interface

Syslog event originated from a node in a remote location is missing fields nodelabel, location, and interface. Attached screenshot below.

It appears that this happens when OpenNMS fails to perform RDNS to resolve the hostname to IP address and thereby not associating the syslog event to a node although the node is provisioned in the requisition. Verified that OpenNMS can only resolve the FQDN of the node and minion can resolve both FQDN and hostname.

Check out the EventBuilder and SyslogMessage class for more info.
