Sending custom Nagios notification emails with coffeescript

Lets imagine for a second that you are using Nagios to monitor systems and services.  Nagios can send you notifications upon events, but the default email notification command is kind of boring.

Lets spice it up with coffeescript!

Nagios

---

define contact{

        contact_name                    mike

        alias                           Mike Kunze

        service_notification_period     24x7

        host_notification_period        24x7

        service_notification_options    w,u,c,r

        host_notification_options       d,r

        service_notification_commands   notify-service-with-nodejs

        host_notification_commands      notify-host-by-email

        email                          

}

define command {

    command_name    notify-service-with-nodejs

    command_line    /opt/bin/notify-service.coffee "$HOSTNAME$" "$SERVICEDESC$" "$HOSTADDRESS$" "$NOTIFICATIONTYPE$" "$SERVICESTATE$" "$LONGDATETIME$" "$SERVICEOUTPUT$"

}
