"nagios.cfg" file to edit. Start "Terminal" and login as administrator then open "nagios.cfg" file with "vi" editor. To do so type in the follows (Figure 5):

vi /usr/local/nagios/etc/nagios.cfg

Edit Nagios' configuration file

Find the following row: /Hilangkan tanda comment-nya
# Definitions for monitoring Windows machine
Press "i" to enter Insert mode and in the row below it, delete the comment mark. The final row will look like as follows (Figure 6):

cfg_file=/usr/local/nagios/etc/objects/windows.cfg

Then press "Escape" and type the follows to exit and save the file:

:wq

Remove comment from configuration file

Now open "windows.cfg" file with "vi" editor. You can do this if you type in the following command :

vi /usr/local/nagios/etc/objects/windows.cfg

Edit windows configuration file

Press "i" to enter Insert mode, then find the row beginning with "address". Now type the IP address of the computer you wish to monitor. In our example the row will look like as follows (Figure 8):

I have already downloaded "sms_send.sh" shell script to the desktop.
download di:
http://www.sms-integration.com/attachments/110/sms_send.sh

isinya sbb:

#!/bin/bash
url1="http://127.0.0.1:9501/api?action=sendmessage&username=admin&password=abc123&recipient=085279959498&messagetype=SMS:TEXT&messagedata="
url2="$@"
url2+=$(php -r "echo rawurlencode('$(sed "s/'/\\\\'/g" <<< )');")
url=$url1+$url2
wget -O- "$url"

Now I copy it to "libexec" directory of Nagios :

cp /home/ozekisms/Desktop/sms_send.sh /usr/local/nagios/libexec/

Please note that "ozekisms" username is only for test purposes, so provide your username instead of it.

Copy the shell script

You can customize the "send_sms.sh" if you change "url1". In our example it is customized in the following way:

#!/bin/bash
url1="http://127.0.0.1:9501/api?action=sendmessage&username=admin&password= abc123&recipient=085279959498&messagetype=SMS:TEXT&messagedata="
url2="$@"
url2+=$(php -r "echo rawurlencode('$(sed "s/'/\\\\'/g" <<< )');")
url=$url1+$url2
wget -O- "$url"

You can customize url1 variable in the following way:
http://127.0.0.1:9501 is the computer on which Ozeki NG SMS Gateway has been installed
username=admin is the username you use to log into Ozeki NG SMS Gateway
password=abc123 is the password of the user
recipient=085279959498 recipient's phone number

Now open "commands.cfg" file with "vi" editor:

vi /usr/local/nagios/etc/objects/commands.cfg

Edit commands configuration file

Press "i" to enter Insert mode and insert a new row after "notify-service-by-email" and "notify-host-by-email" and provide the following commands

# 'notify-service-by-sms' command definition
define command{
command_name    notify-service-by-sms
command_line      /usr/local/nagios/libexec/sms_send.sh "--Nagios Service Notification-- Host: $HOSTNAME$, State: $HOSTSTATE$ Service $SERVICEDESC$ Description: $SERVICESTATE$ Time: $LONGDATETIME$"

} # 'notify-host-by-sms' command definition
define command{
command_name    notify-host-by-sms
command_line      /usr/local/nagios/libexec/sms_send.sh "--Nagios Host Notification-- Host: $HOSTNAME$, State: $HOSTSTATE$, Time: $LONGDATETIME$"
}

Then press "Escape" and type the follows to exit and save the file:

:wq

Open "contacts.cfg" file with "vi" editor :

vi /usr/local/nagios/etc/objects/contacts.cfg

Edit contacts file

Press "i" to enter Insert mode and insert a new row before the one beginning with "e-mail". Type the follows :

service_notification_commands notify-service-by-sms host_notification_commands notify-host-by-sms

Notification commands for admin

Then press "Escape" and type the follows to exit and save the file:

:wq

Then restart Nagios service to have changes come into operation. Type in the following command:

service nagios restart

Restart Nagios service

After Nagios has been restarted, start your web browser and type in the follows:

http://localhost/nagios

Login with the default username which has been created during the installation (nagiosadmin), and with your provided password. Now you can see that there is a critical error on the monitored computer. The Explorer service reports this error. You can see at "Last Notification" row that Nagios has already sent the notification
