+## SAMPLE GLUSTER CLUSTER CONFIGURATION FOR NAGIOS
+##
+## This is an example of how Nagios can be configured to monitor your
+## gluster cluster. Please use this as a reference.
+## The sample configures a cluster "test-cluster" both as a host group
+## and host. Volume and Cluster services are under the host "test-cluster"
+##
