Step by Step Nagios untuk OZEKI NG

Assumption:

– Nagios server and clients are configured and running
– Mobile tethering is enabled and support unlimited SMS
– Ozeki NG SMS gateway server is running

All above three assumptions have been explained in this blog previously. Kindly do visit and start monitoring your infrastructure efficiently.

Step 1: Install SMS plugin in nagios server

[root@server.local ~]# vi /usr/local/nagios/libexec/nagios_sms.sh

Copy and paste the below lines

#!/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"

where,

http://127.0.0.1:9501 — the computer Ozeki NG SMS Gateway has been installed
username=admin — username you use to log into Ozeki NG SMS Gateway
password=abc123 — password of the user
recipient=085279959498 — recipient’s phone number

Step 2: Define command for nagios sms plugin

[root@server.local ~]# vi /usr/local/nagios/etc/objects/commands.cfg

Copy and paste the below lines

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

Save and Exit (:wq!)

Step 3: Define contacts

[root@server.local ~]# vi /usr/local/nagios/etc/objects/contacts.cfg

Copy and insert the below lines in nagiosadmin template

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

It looks like below changes;

define contact{
contact_name nagiosadmin
use generic-contact
alias Nagios Admin
service_notification_commands notify-service-by-sms
host_notification_commands notify-host-by-sms
email nagios@localhost
}

Save and Exit (:wq!)

Step 4: Restart the nagios

[root@server.local ~]# /etc/init.d/nagios restart

That’s it.. Now nagios alerts are triggered to SMS gateway server and finally recipient start receiving alerts.
