Where -v is the volume name, and -n is the expected number of bricks.

#Called via NRPE#

#Deployment# Add to nrpe.cfg.

command[check_gluster]=/usr/local/nagios/libexec/check_gluster.pl -v data -n 4 

The script wraps a call to gluster, and that command needs to be run as root, so you might need to add something similar to your sudoers.

Defaults:nagios !requiretty
nagios ALL=NOPASSWD:/usr/sbin/gluster volume info data

Put this in command.cfg on your nagios server.

define command{ command_name check-gluster-status command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c check_gluster }

Define the service, and you're done.

define service{ 
       use generic-service 
     hostgroup_name gluster-hosts
     service_description gluster_status
     check_command check-gluster-status
     notifications_enabled 0
     }
