To learn more about the tool, I invite you to visit the official site at http://www.centreon.com

What we need? ?

Apache
PHP 5.3.x + a lot of dependencies
Mysql
Nagios
Pear + a lot of dependencies
Perl + a lot of dependencies
rrdtool
snmp
sudo
Centreon (obvious :-p)

Starting installation of packages

For this tutorial, we will use the tool portmaster, you can even do all the installation manually, but I advise u to use the tool in order to facilitate the installation of the dependencies and the amount of packages that we need.

/usr/ports/ports-mgmt/portmaster
make install clean

if you are using csh shell

rehash

We start by some common packages to provide the Centreon:

# In the package configurations, keep the default settings or to your liking.
portmaster -d lang/perl5.12 www/apache22 shells/bash security/sudo net-mgmt/net-snmp net-mgmt/snmptt

Installing our database (if using MySQL outside, only install mysql-client)

portmaster -d databases/mysql51-client databases/mysql51-server

Let’s go, install the PHP:

Attention to configure PHP5 package, you need some options checked, at least those which are listed below:

 │ │ [*] CLI        Build CLI version                               │ │
 │ │ [*] APACHE     Build Apache module                             │ │

	graphics/pear-Image_GraphViz

Let’s go to the part of Perl:

portmaster -d devel/p5-Config-IniFiles graphics/p5-GD 
	databases/p5-DBD-mysql security/p5-Crypt-DES 
	security/p5-Digest-HMAC net-mgmt/p5-Net-SNMP

An important tool that can not miss in our environment:

portmaster -d databases/rrdtool

And our background of Centreon, Nagios!

portmaster -d net-mgmt/nagios net-mgmt/ndoutils

Check the options:

│ │[X] EMBEDDED_PERL   Enable embedded Perl [requires Perl 5.8.0+] │ │
│ │[X] NANOSLEEP       Use nanosleep in event timing               │ │
│ │[X] EVENT_BROKER    Enable event broker functionality           │ │

ndoutils:

│ │ [X] MYSQL  MySQL Backend  			                   │ │

Let’s settings for some packages:

if you are using csh shell

rehash

PHP:

cd /usr/local/etc
cp php.ini-production php.ini
# Set the time zone for your location
perl -p -i -e 's/;date.timezone =/date.timezone = America/Sao_Paulo/' /usr/local/etc/php.ini

Apache:

echo 'apache22_enable="YES"' >> /etc/rc.conf
echo "AddType application/x-httpd-php .php" >> /usr/local/etc/apache22/Includes/php.conf
echo "AddType application/x-httpd-php-source .phps" >> /usr/local/etc/apache22/Includes/php.conf
perl -p -i -e 's/DirectoryIndex index.html/DirectoryIndex index.html index.php/g' /usr/local/etc/apache22/httpd.conf
 
# Make sure your hosts file (/etc/hosts) or internal DNS is working properly
/usr/local/etc/rc.d/apache22 start

Mysql:

echo 'mysql_enable="YES"' >> /etc/rc.conf
/usr/local/etc/rc.d/mysql-server start
# set the root password for mysql
mysqladmin -u root password "new-password"

SNMP:

echo 'snmpd_enable="YES"' >> /etc/rc.conf
echo 'snmpd_flags="-a"' >> /etc/rc.conf
echo 'snmpd_conffile="/usr/local/etc/snmp/snmpd.conf"' >> /etc/rc.conf
echo 'snmptrapd_enable="YES"' >> /etc/rc.conf
echo 'snmptrapd_flags="-a -p /var/run/snmptrapd.pid"' >> /etc/rc.conf
 
mkdir -p /usr/local/etc/snmp
cp /usr/local/share/snmp/snmpd.conf.example /usr/local/etc/snmp/snmpd.conf
perl -p -i -e 's/rocommunity public  default    -V systemonly/rocommunity public default/g' /usr/local/etc/snmp/snmpd.conf
perl -p -i -e 's/agentAddress  udp:127.0.0.1:161/#agentAddress  udp:127.0.0.1:161/' /usr/local/etc/snmp/snmpd.conf
/usr/local/etc/rc.d/snmpd start
/usr/local/etc/rc.d/snmptrapd start

Fix the file /usr/local/etc/snmp/snmpd.conf with location information and identification.

If you are installing snmpd in a Jail, see this article for the same operation in Jail:
http://ggeek.blogspot.com/2008/10/freebsd-jails-and-net-snmp.html

Nagios:

sh
cd /usr/local/etc/nagios/
ls -1 *-sample | while read arq ; do mv $arq `echo $arq | cut -f1 -d'-'` ; done
cd objects/
ls -1 *-sample | while read arq ; do mv $arq `echo $arq | cut -f1 -d'-'` ; done
exit
echo 'nagios_enable="YES"' >> /etc/rc.conf
/usr/local/etc/rc.d/nagios start

NDOUtils:

echo 'ndo2db_enable="YES"' >> /etc/rc.conf

Download Centreon:

cd /tmp
fetch http://download.centreon.com/centreon/centreon-2.3.3.tar.gz
tar zxf centreon-2.3.3.tar.gz
cd centreon-2.3.3

Making Centreon read the bash shell

There are two ways (choose one):

- Changing the path the scripts Centreon:

perl -p -i -e 's//bin/bash//usr/local/bin/bash/g' install.sh
perl -p -i -e 's//bin/bash//usr/local/bin/bash/g' libinstall/*

- Creating a symbolic link in /bin

ln -s /usr/local/bin/bash /bin/bash

Some preparations for the installation:

mkdir -p /tmp/cron.d
fetch -o tmpl/vardistrib/freebsd http://www.luizgustavo.pro.br/downloads/freebsd.txt

Now start the installation via the command:

bash install.sh -f tmpl/vardistrib/freebsd

Follow the installation process through the video below:

After installation, we will leave for the web part to do so, restart MySQL and Apache:

/usr/local/etc/rc.d/apache2 restart
/usr/local/etc/rc.d/mysql-server restart

We fix some patches of permission:

chown -R www:www /usr/local/etc/centreon/
cd /usr/local/centreon
rm filesGeneration
mv /var/cache/centreon/filesGeneration .
chown -R www:www filesGeneration
rm filesUpload
mv /var/cache/centreon/filesUpload .
chown -R www:www filesUpload
cd /var/cache/centreon
ln -s /usr/local/centreon/filesGeneration
ln -s /usr/local/centreon/filesUpload

We also fix a problem of dependence on the version of PEAR:

/usr/local/bin/pear uninstall HTML_QuickForm_advmultiselect 
/usr/local/bin/pear install -f pear/HTML_QuickForm_advmultiselect-1.2.0

Now this way, we can point to our broswer centreon server address:

http:///centreon

Follow the video to configure the web:

There is less, we still need to export the configuration files for our NDO-Utils to work for it, follow the export of the same video on the web:

Now, let’s start the processes of Centreon:

pw user mod nagios -s /bin/sh
/usr/local/etc/rc.d/centcore start
/usr/local/etc/rc.d/centstorage start

Setting the part of the CRON to FreeBSD:

cat /tmp/cron.d/* >> /etc/crontab
/etc/rc.d/cron restart
rm -rf /tmp/cron.d

Restart nagios processes and ndoutils

/usr/local/etc/rc.d/nagios restart
/usr/local/etc/rc.d/ndo2db restart

Ready! Now just configure your hosts and start monitoring.

If you need support Centreon, contact the Mundounix, we offer support and advice for network monitoring solution.

Fazendo download do Centreon:

cd /tmp
fetch http://download.centreon.com/centreon/centreon-2.3.3.tar.gz
tar zxf centreon-2.3.3.tar.gz
cd centreon-2.3.3

Fazendo o Centreon ler o shell bash

Existem 2 maneiras (escolha uma):

- Alterando o caminho nos scripts do Centreon:

perl -p -i -e 's/\/bin\/bash/\/usr\/local\/bin\/bash/g' install.sh
perl -p -i -e 's/\/bin\/bash/\/usr\/local\/bin\/bash/g' libinstall/*

- Criando um link simbolico no /bin

ln -s /usr/local/bin/bash /bin/bash

Alguns preparativos para a instalação:

mkdir -p /tmp/cron.d
fetch -o tmpl/vardistrib/freebsd http://www.luizgustavo.pro.br/downloads/freebsd.txt

Inicie agora a instalação via comando:

bash install.sh -f tmpl/vardistrib/freebsd

Acompanhe o processo de instalação através do video abaixo:

Terminada a instalação, vamos partir para a parte web, para isso, reinicie o MySQL e o Apache:

/usr/local/etc/rc.d/apache2 restart
/usr/local/etc/rc.d/mysql-server restart

Vamos acertar algumas correções de permissão:

chown -R www:www /usr/local/etc/centreon/
cd /usr/local/centreon
rm filesGeneration
mv /var/cache/centreon/filesGeneration .
chown -R www:www filesGeneration
rm filesUpload
mv /var/cache/centreon/filesUpload .
chown -R www:www filesUpload
cd /var/cache/centreon
ln -s /usr/local/centreon/filesGeneration
ln -s /usr/local/centreon/filesUpload

Vamos corrigir também um problema de versão de dependência do PEAR:

/usr/local/bin/pear uninstall HTML_QuickForm_advmultiselect 
/usr/local/bin/pear install -f pear/HTML_QuickForm_advmultiselect-1.2.0

Agora assim, podemos apontar nosso navergador para o endereço do servidor centreon:

http:///centreon

Acompanhe o vídeo para configurar via web:

Falta pouco, ainda precisamos exportar os arquivos de configuração para que nosso NDO-Utils possa funcionar, para isso, acompanhe o vídeo na exportação do mesmo via web:

Agora, vamos iniciar os processos do Centreon:

pw user mod nagios -s /bin/sh
/usr/local/etc/rc.d/centcore start
/usr/local/etc/rc.d/centstorage start

Acertar a parte da CRON para o FreeBSD:

cat /tmp/cron.d/* >> /etc/crontab
/etc/rc.d/cron restart
rm -rf /tmp/cron.d

Reinicie os processos do nagios e ndoutils

/usr/local/etc/rc.d/nagios restart
/usr/local/etc/rc.d/ndo2db restart

Pronto ! agora é só configurar os seus hosts e iniciar o monitoramento.

Notificação do Nagios no Gtalk

luizgustavo — Sat, 06 Mar 2010 00:21:19 +0000

Essa dica e pra quem quer receber notificações de mensagens do nagios através de uma conta do gtalk, assim você pode receber na hora um alerta do nagios no seu cliente de gtalk (seja no seu desktop ou celular)

Essa dica eu peguei do site: http://www.gridpp.ac.uk/wiki/Nagios_jabber_notification

Vou mostrar aqui como configurar em um FreeBSD:

Satisfazendo algumas dependências do perl para o script:

cd /usr/ports/net-im/p5-Net-XMPP
make install clean
cd /usr/ports/security/p5-IO-Socket-SSL
make install clean

A partir dai podemos criar o nosso script:

#!/usr/bin/perl -w
#
# script for nagios notify via Jabber / Google Talk Instant Messaging
#   using XMPP protocol and SASL PLAIN authentication.
#
# author: Andrew Elwell
# based on work by Thus0
 and  David Cox
#
# released under the terms of the GNU General Public License v2
# Copyright 2007 Andrew Elwell.
 
use strict;
use Net::XMPP;
 
## Configuration
my $username = "your.google.username";
my $password = "your.google.password";
my $resource = "nagios";
## End of configuration
 
my $len = scalar @ARGV;
if ($len ne 2) {
 die "Usage...\n $0 [jabberid] [message]\n";
}
my @field=split(/,/,$ARGV[0]);
#------------------------------------
 
# Google Talk & Jabber parameters :
 
my $hostname = 'talk.google.com';
my $port = 5222;
my $componentname = 'gmail.com';
my $connectiontype = 'tcpip';
my $tls = 1;
 
#------------------------------------
 
my $Connection = new Net::XMPP::Client();
 
# Connect to talk.google.com
my $status = $Connection->Connect(
 hostname => $hostname, port => $port,
 componentname => $componentname,
 connectiontype => $connectiontype, tls => $tls);
 
if (!(defined($status))) {
 print "ERROR:  XMPP connection failed.\n";
 print "        ($!)\n";
 exit(0);
}
 
# Change hostname
my $sid = $Connection->{SESSION}->{id};
$Connection->{STREAM}->{SIDS}->{$sid}->{hostname} = $componentname;
 
# Authenticate
my @result = $Connection->AuthSend(
 username => $username, password => $password,
 resource => $resource);
 
if ($result[0] ne "ok") {
 print "ERROR: Authorization failed: $result[0] - $result[1]\n";
 exit(0);
}
 
# Send messages
foreach ( @field ) {
$Connection->MessageSend(
 to       => "$_\@$componentname",
 resource => $resource,
 subject  => "Notification",
 type     => "chat",
 body     => $ARGV[1]);
}

Altere as opcoes no script conforme os dados de sua conexao no Gtalk

Dai configure no seu nagios (ou Centreon) o seu comando de notificacao:

# 'host-notify-by-jabber' command definition
define command{
 command_name    host-notify-by-jabber
 command_line    /usr/local/bin/notify_via_jabber $CONTACTPAGER$ "Host '$HOSTALIAS$' is $HOSTSTATE$ - Info
: $HOSTOUTPUT$"
 }
 
# 'notify-by-jabber' command definition
define command{
 command_name    notify-by-jabber
 command_line    /usr/local/bin/notify_via_jabber $CONTACTPAGER$ "$NOTIFICATIONTYPE$ $HOSTNAME$ $SERVICED
ESC$ $SERVICESTATE$ $SERVICEOUTPUT$ $LONGDATETIME$"
 }

Centreon: Nova versão estável 2.1
