Comment 1 Steven Hardy 2013-10-08 13:50:19 UTC 
Ok, so further info after some investigation:

1. The problem is that packstack/puppet won't create the /etc/nagios/nrpe.cfg file if it doesn't exist, simply doing "touch /etc/nagios/nrpe.cfg" allows the file to be populated:

2. Even after the file is populated, there are config problems with the 
/etc/nagios/nagios_host.cfg and 
/etc/nagios/nagios_command.cfg files, which mean starting nagios fails:

# systemctl restart nagios.service
Job for nagios.service failed. See 'systemctl status nagios.service' and 'journalctl -xn' for details.
[root@t430slt ~]# systemctl status nagios.service
nagios.service - SYSV: Starts and stops the Nagios monitor
   Loaded: loaded (/etc/rc.d/init.d/nagios)
   Active: failed (Result: exit-code) since Tue 2013-10-08 14:36:46 BST; 10s ago
  Process: 10941 ExecStart=/etc/rc.d/init.d/nagios start (code=exited, status=1/FAILURE)

Oct 08 14:36:46 t430slt systemd[1]: nagios.service: control process exited, code=exited status=1
Oct 08 14:36:46 t430slt systemd[1]: Failed to start SYSV: Starts and stops the Nagios monitor.
Oct 08 14:36:46 t430slt systemd[1]: Unit nagios.service entered failed state.

The problems are:
- /etc/nagios/nagios_command.cfg contains a duplicate cinder-list section
- /etc/nagios/nagios_host.cfg contains a duplicate linux-server section for localhost.
Comment 2 Ivan Chavero 2013-10-11 20:26:51 UTC 
Added the creation of the file on the puppet modules.
