Description of problem:
------------------------

The status information column, for the RHS node on which nagios server is running, is shown as 'null' in the 'Hosts' screen.

Following are the contents of the configuration file for the node - 

define host{
   use gluster-host
   host_name node1
   alias web-node01
   address localhost
   hostgroups gluster_hosts
}

Find screenshot attached.

Version-Release number of selected component (if applicable):
nagios-3.5.1-1.el6.x86_64
glusterfs-3.4.0.59rhs-1.el6rhs.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install nagios server and the required packages for a storage node to be monitored on one of the RHS nodes. The configuration file with the above contents would typically be present after installation.
2. Start the required services and navigate to the Nagios web UI.
3. Click on Hosts in the list on the left-hand side of the screen.

Actual results:
Status information for the node running the nagios server is null.

Expected results:
The status information for the RHS node running the nagios server should be displayed correctly, and not as 'null'.
