Now restart your Icinga 2 daemon to finish the installation!
Add director-global zone.
monitoring$ cat << EOF | sudo tee -a /etc/icinga2/zones.conf
object Zone "director-global" {
global = true
}
EOF
Clean up local configuration on this node.
monitoring$ sudo echo -n | sudo tee /etc/icinga2/conf.d/{apt.conf,commands.conf,groups.conf,hosts.conf,downtimes.conf,notifications.conf,satellite.conf,services.conf,templates.conf,timeperiods.conf,users.conf}
Restart icinga2 service on this node.
$ sudo service restart icinga2
Verify that everything works.
Additional notes
You can use the Director-assisted setup to configure a top down approach.
Feel free to experiment.
