Adding Centos 6.4 Samba Server to Nagois Monitoring Server

Install NRPE on Clients (Nagios Clients)


#rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

#rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

#yum -y install nagios nagios-plugins-all nrpe

#chkconfig nrpe on

This next step is where you get to specify any manual commands that Monitoring server can send via NRPE to these client hosts.

Make sure to change allowed_hosts to your own values.


#vim /etc/nagios/nrpe.cfg



log_facility=daemon
pid_file=/var/run/nrpe/nrpe.pid
server_port=5666
nrpe_user=nrpe
nrpe_group=nrpe
allowed_hosts=198.211.117.251
dont_blame_nrpe=1
debug=0
command_timeout=60
connection_timeout=300
include_dir=/etc/nrpe.d/
command[check_users]=/usr/lib64/nagios/plugins/check_users -w 5 -c 10
command[check_load]=/usr/lib64/nagios/plugins/check_load -w 15,10,5 -c 30,25,20
command[check_disk]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sda1,sda2,sda3
command[check_zombie_procs]=/usr/lib64/nagios/plugins/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=/usr/lib64/nagios/plugins/check_procs -w 150 -c 200
command[check_procs]=/usr/lib64/nagios/plugins/check_procs -w $ARG1$ -c $ARG2$ -s $ARG3$

We should also setup firewall rules to allow connections from our Monitoring server to those clients and drop everyone else:


iptables -N NRPE
iptables -I INPUT -s 0/0 -p tcp --dport 5666 -j NRPE
iptables -I NRPE -s 198.211.117.251 -j ACCEPT
iptables -A NRPE -s 0/0 -j DROP

Save the Iptables Entires


# /etc/init.d/iptables save

Start the nrpe Service as Below :


# service nrpe start

Add Server Configuration on monitoring Server


#sudo vim /etc/nagios3/conf.d/sambafileserver_nagios2.cfg

Add the following lines


define host {
        use                   	        generic-host
        host_name              	        sambafileserver

        check_command                   check_ping!100.0,20%!500.0,60%
        }

define service {
        use                             generic-service		; Name of service template to use
        host_name                       sambafileserver

        check_command                   check_ssh
        notifications_enabled           0
        }
define service{
        use                             generic-service         ; Name of service template to use
        host_name                       sambafileserver
        service_description             Current Load
        check_command                   check_load!5.0!4.0!3.0!10.0!6.0!4.0
}

Finally, after you are done adding all the client configurations, you should set folder permissions correctly and restart Nagios on your Monitoring Server:


# chown -R nagios. /etc/nagios

# service nagios restart

Open the browser and Entire Your Nagios Servers Ip/nagois3 version (http://192.168.1.20/nagios3) And entire Your User as nagiosadmin Password as ur Given ..
