Note: These instructions are debian based.

##Step 1## Download send_textbelt_sms to /usr/local/nagios/libexec

chmod +x send_textbelt_sms

replace REPLACEWITHPHONENUMBER with your phone number e.g. 8185551213

##Step 2##

Add the following lines to commands.cfg

sudo nano /usr/local/nagios/etc/objects/commands.cfg

'notify-service-by-sms' command definition

define command{ command_name notify-service-by-sms command_line /usr/local/nagios/libexec/send_textbelt_sms "--Nagios Service Notification-- Host: $HOSTNAME$, 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/send_textbelt_sms "--Nagios Host Notification-- Host: $HOSTNAME$, State: $HOSTSTATE$, Time: $LONGDATETIME$" }

##Step 3 ## Modify contacts.cfg sudo nano /usr/local/nagios/etc/objects/contacts.cfg

Modify your contact definition to look like the following:

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_commands notify-service-by-sms ;sms notices host_notification_commands notify-host-by-sms ;sms notices email youremailaddy@xyz.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ****** }

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