             usage
             exit 1
             ;;

         ?)
             usage
             exit
             ;;
         
     esac

Send SMS through a script example:

/etc/nagios/objects/schosts.cfg

./sendsms_vutlan -H 192.168.0.193 -p secret -P +777 -m 'This is a text'

where 192.168.0.193 - address of the master unit with GSM modem;
       secret - user password for the master unit with GSM modem;
       +777 - phone number to send a message;
       'This is a text' - forwarded message text;

In order to bind the current script to Nagios, you must create a notification command in the Nagios configuration file:

/etc/nagios/objects/commands.cfg

define command{
        command_name notify-service-by-sms
        command_line $USER1$/sendsms_vutlan -H 192.168.1.190 -p guest -P $CONTACTPAGER$ -m "Nagios – $NOTIFICATIONTYPE$ : $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$"
}
define command{
        command_name notify-host-by-sms
        command_line $USER1$/sendsms_vutlan -H 192.168.1.190 -p guest -P $CONTACTPAGER$ -m "Nagios – $NOTIFICATIONTYPE$ : Host $HOSTALIAS$ is $HOSTSTATE$"
}

You must also create or edit a Nagios contact:

/etc/nagios/objects/contacts.cfg

define contact{
        contact_name                    nagiosadmin             ; Short name of user
        use                             generic-contact         ; Inherit default values from generic-contact template (defined above)
        alias                           Nagios Admin            ; Full name of user
        service_notification_options    w,u,c,r
        host_notification_options       d,u,r
        service_notification_commands   notify-service-by-email,notify-service-by-sms
        host_notification_commands      notify-host-by-email,notify-host-by-sms
        email                           nagios@localhost        ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******
        pager                           +329999999999           ; <<***** CHANGE THIS TO YOUR PHONE NUMBER ******
}
