I tried to build a minimal setup to use the Syslog-Northbounder to forward Alarms to a syslog server. I build a minimal setup on CentOS 6.5 with rsyslog. The configuration from my rsyslog daemon is attached on the issue. I've also attached my syslog-northbounder-configuration.xml. In my example the rsyslog server is running on localhost listening on TCP/127.0.0.1:514. Syslogd in OpenNMS is not running. The setup is just in a test environment so I don't filter UEI's and want to forward all generated OpenNMS Alarms to syslog. In Alarmd log file the following error message appears after creating an outage for a node by setting a null route to the IP address.
This issue can be verified running the OpenNMS Vagrant box and using the two configuration files attached to this issue. http://www.opennms.org/wiki/OpenNMS_and_Vagrant_with_VirtualBox
