Pada server Nagios (Wheezy):

1. Install pakej-pakej yang diperlukan:
   apt-get install nagios3 nagios-plugins nagios-nrpe-plugin
2. Buatkan fail /etc/nagios3/conf.d/dns-mylab.cfg seperti berikut:

   [code lang=’plain’]define host{
   use generic-host
   host_name dns
   alias dns-mylab
   address 192.168.1.102
   }
   define service{
   use generic-service
   host_name dns
   service_description Current Load
   check_command check_nrpe_1arg!check_load
   }
   define service{
   use generic-service
   host_name dns
   service_description Current Users
   check_command check_nrpe_1arg!check_users
   }
   define service{
   use generic-service
   host_name dns
   service_description Disk Space
   check_command check_nrpe_1arg!check_root
   }
   define service{
   use generic-service
   host_name dns
   service_description Total Processes
   check_command check_nrpe_1arg!check_total_procs
   }[/code]

   [code lang=’plain’]#server_address=127.0.0.1
   server_address=192.168.1.102

   #allowed_hosts=127.0.0.1
   allowed_hosts=192.168.1.110

   #command[check_hda1]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /dev/hda1
   command[check_root]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /dev/mapper/debian-root[/code]
