1. Setup of a Central server with engine: Nagios, Broker: ndo2d, database: local MySql Now we start preparing an Ubuntu Server 10.04 system to become a Central Centreon using Nagios engine to check hosts and services status and ndo2db to send data to its local MySql database. 1.1 Central: Ubuntu server setup

Start with ubuntu-10.04.3-server-amd64.iso a default system setup. User created cristian/password ( sudo password = password).

Switch to fixed IP address vi /etc/network/interfaces

Please verify that you are working with fixed IP address. If not, please change your settings. You should see something like this at the end of the file (the value should be different for you):

auto lo iface lo inet loopback # The primary network interface auto eth0 # iface eth0 inet dhcp iface eth0 inet static address 10.77.3.120 netmask 255.255.252.0 network 10.77.0.0 broadcast 10.77.3.255 gateway 10.77.2.255

Modify also resolv.conf to set dns server vi /etc/resolv.conf

1.4 Central: Nagios setup

- 11 -

Create nagios user /usr/sbin/useradd -m -s /bin/bash nagios passwd nagios (remember this password for future poller setup)

On older Ubuntu server editions you will need to also add a nagios group (it's not created by default). You should be able to skip this step on desktop, or newer server editions of Ubuntu.

Create a new nagios group for allowing external commands to be submitted through the web interface. Add both the nagios user and the apache user to the group.

/usr/sbin/groupadd nagios /usr/sbin/usermod -a -G nagios nagios /usr/sbin/usermod -a -G nagios www-data cd /usr/local/src/ wget http://downloads.sourceforge.net/project/nagio s/nagios-3.x/nagios-3.3.1/nagios-3.3.1.tar.gz tar -xzf nagios-3.3.1.tar.gz cd nagios ./configure --prefix=/usr/local/nagios --with-comma nd-group=nagios --enable-nanosleep --enable-event-broker make all make install make install-init make install-commandmode make install-config cd /usr/local/nagios/var/ mkdir spool cd spool mkdir checkresults cd /usr/local/nagios/ chown nagios:nagios -R var chmod 777 -R var export PATH="$PATH:/usr/local/nagios/bin/"

1.5 Central: Nagios Plugins setup cd /usr/local/src/ wget http://downloads.sourceforge.net/project/nagiosplug /nagiosplug/1.4.15/nagios-plugins-1.4.15.tar.gz tar -xzf nagios-plugins-1.4.15.tar.gz

- 12 -

cd nagios-plugins-1.4.15 ./configure --with-nagios-user=nagios --with-nagios -group=nagios --with-openssl=/usr/bin/openssl --enable-perl-modules make make install

1.6 Central: Ndoutils setup cd /usr/local/src wget http://prdownloads.sourceforge.net/sourceforge /nagios/ndoutils-1.4b9.tar.gz tar -xzf ndoutils-1.4b9.tar.gz cd ndoutils-1.4b9 wget http://svn.centreon.com/trunk/ndoutils-patch/n doutils1.4b9_light.patch patch -p1 -N < ndoutils1.4b9_light.patch

configuration and installation ./configure --prefix=/usr/local/nagios/ --enable-my sql --disable-pgsql \ --with-ndo2db-user=nagios --with-ndo2db-group=na gios Make

manual installation :

After creating the binaries and libraries they have to be copied

cd /usr/local/src/ndoutils-1.4b9/src cp ndomod-3x.o /usr/local/nagios/bin/ndomod.o cp ndo2db-3x /usr/local/nagios/bin/ndo2db cd /usr/local/src/ndoutils-1.4b9/config cp ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.c fg cp ndomod.cfg-sample /usr/local/nagios/etc/ndomod.c fg chmod 777 /usr/local/nagios/bin/ * chown nagios:nagios /usr/local/nagios/bin/ndo*

make ndo2db daemon autorun

Install the ndo init script by copying it from the ndoutils to the init directory and making it executable by running

cd /usr/local/src/ndoutils-1.4b9 cp daemon-init /etc/init.d/ndo2db chmod +x /etc/init.d/ndo2db

Then add it to your init runlevel to load it automatically when starting/restarting your server. For Debian/Ubuntu do as root or with sudo:

update-rc.d ndo2db defaults

Check if process is running and if tcp port is being used:

- 13 -

ps –f | grep ndo2db netstat -apn |grep 5668

1.7 Central: Enable snmp

vi /etc/default/snmpd

and change these sections:

#SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'

SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p / var/run/snmpd.pid 127.0.0.1 10.77.3.120'

Where 10.77.3.120 is the host / network allowed to ask for snmp entries.

#TRAPDRUN=no

TRAPDRUN=yes

Edit snmpd configuration file:

vi /etc/snmp/snmpd.conf

and change this section:

# sec.name source community

#com2sec paranoid default public

com2sec readonly default public

com2sec readonly 127.0.0.1 public

com2sec readonly 192.168.0.0/24 public

#com2sec readwrite default private

Or more simply :


delete all the content of this file and type: rocommunity public service snmpd restart

1.8 Central: Check services sysv-rc-conf Check Apche2, MySQL , Nagios , ndo2db , snmpd to st artup at 2,3,4 and 5 runlevel And reboot

1.9 Central: Install Centreon

- 15 -

Remember if you have not done before:

export PATH="$PATH:/usr/local/nagios/bin/"

Then follow these steps

cd /usr/local/src wget http://download.centreon.com/centreon/centreon -2.3.4.tar.gz tar -xzf centreon-2.3.4.tar.gz cd centreon-2.3.4 ./install.sh –i ################################################### ############################ # # # Centreon (www.centreon.co m) # # Thanks for using Centreo n # # # # v2.3 # # # # [email protected] # # # # Make sure you have installed an d configured # # sudo - sed - php - apache - rrd tool - mysql # # # ################################################### ############################ --------------------------------------------------- --------------------- Checking all needed binaries --------------------------------------------------- --------------------- rm OK cp OK mv OK /bin/chmod OK /bin/chown OK echo OK more OK mkdir OK find OK /bin/grep OK /bin/cat OK /bin/sed OK You will now read Centreon Licence.

If these steps are succesfully completed, you should be able to log on to the satellite monitor via SSH without entering a password. Verify that you could access to the satellite without password prompt: ssh [email protected]

From central centreon Synchronize commands with the satellite (only if you are using the same architecture on both side 32bits or 64bits): scp /usr/local/nagios/libexec/* [email protected]:/usr/local/nagios/ libexec scp /usr/local/nagios/bin/ndomod.o [email protected]:/usr/local/nagios/ bin if you encounter access denied errors like: scp: /usr/local/nagios/libexec/check_dhcp: Permissi on denied

Delete files from satellite and resync again with scp. 2.21 Central: Add Poller to Centreon configuration On the poller: cd /usr/local/nagios/etc rm *

- 54 -

Connect to the Centreon interface and configure the satellite monitor. Configuration > Centreon > Pollers > Add (Status: enabled, Localhost: no, IP address, etc.)

Next, duplicate the ndomod configuration for the new poller. Configuration > Centreon > ndomod.cfg. Select action "Duplicate". (Status: enabled, Requester: the name of the freshly created poller, IP address: the IP address of the central server, Instance name: must be unique)

Ndo2db not needed

- 55 -

Next, also duplicate the nagios configuration for the new poller. Configuration > Nagios > nagios.cfg Select action "Duplicate". (Status: enabled, Server Nagios configured: the name of the freshly created poller)

Finalization: Make sure centcore is running on the central server. If it is not running, start it: Reboot both central and poller Hosts configuration

Finally, attach host/services to the new poller and generate the configuration for all servers, take a beer and watch your setup go.

Save and restart nagios Check ndo2db if communication is working: root@central:/# netstat -apn |grep 5668 tcp 0 0 0.0.0.0:5668 0.0.0.0 :* LISTEN 769/ndo2db

3. Setup of a Central server with engine: Nagios, Broker: ndo2d, database: external MySql and setup of its Poller server with engine: Nagios using ndomod

Now we start preparing an Ubuntu Server 10.04 system to become a mysql external database server for a Centreon Central server.

From central centreon Synchronize commands with the satellite (only if you are using the same architecture on both side 32bits or 64bits): scp /usr/local/nagios/libexec/* [email protected]:/usr/local/nagios/ libexec scp /usr/local/nagios/bin/ndomod.o [email protected]:/usr/local/nagios/ bin if you encounter access denied errors like: scp: /usr/local/nagios/libexec/check_dhcp: Permissi on denied

Delete files from satellite and resync again with scp. 3.29 Central: Add Poller to Centreon configuration

- 95 -

On the poller: cd /usr/local/nagios/etc rm *

Connect to the Centreon interface and configure the satellite monitor. Configuration > Centreon > Pollers > Add (Status: enabled, Localhost: no, IP address, etc.)

Next, duplicate the ndomod configuration for the new poller. Configuration > Centreon > ndomod.cfg. Select action "Duplicate". (Status: enabled, Requester: the name of the freshly created poller, IP address: the IP address of the central server, Instance name: must be unique)

- 96 -

Ndo2db not needed

Next, also duplicate the nagios configuration for the new poller. Configuration > Nagios > nagios.cfg Select action "Duplicate". (Status: enabled, Server Nagios configured: the name of the freshly created poller)

Finalization: Make sure centcore is running on the central server. If it is not running, start it: Reboot both central and poller Hosts configuration

Finally, attach host/services to the new poller and generate the configuration for all servers, take a beer and watch your setup go.

Save and restart nagios

5. Setup of a Central server with engine: Nagios, Broker: Centreon-Broker, database: local MySql and setup of its Poller server with engine: Nagios, Broker: Centreon-Broker CentreonBroker's usage is pretty simple. But first let's have an overview of how the whole system works. As you might know (if not you probably wouldn't be here), the goal of Centreon Broker is to store Nagios events in a database. When monitoring services and hosts, Nagios generates differents kinds of events to notify if a check has been executed or if a service state has changed for example. Those events are processed internally by Nagios and cannot be exported by default. To do this, we will have to load a module within the Nagios process. Once loaded, the module will be able to convert Nagios event structures to a data stream (which is just raw data).

The next step is to retrieve the (potential multiple) data streams from the Nagios instance and store them in a database. Centreon Broker can listen on a or multiple sockets (IPv4, IPv6 or Unix) for a connection from the Nagios module. Each event data will be fetched and transfered to your favorite database.

5.1 Central: Ubuntu server setup Now we start preparing an Ubuntu Server 10.04 system to become a Central Centreon using Nagios engine to check hosts and services status and Centreon-Broker to send data its local MySql database.

Building Centreon Broker¶

Overview

To build Centreon Broker, you will need the following external dependencies :

• a C++ compilation environment. • CMake, a cross-platform build system. • the Qt framework with QtCore, QtSql and QtXml modules. • RRDTool development files (for the RRD module).

And you need to get Centreon Broker sources (see in the "Checkout Centreon Broker" section).

Centreon Broker is compatible only with Unix-like platforms (Linux, FreeBSD, Solaris, ...).

Dependencies

In binary form

Some OS provides binary versions of some dependencies required by Centreon Broker. To install them, use the standard package installation tool of your plateform (apt on Debian and Ubuntu, yum on Fedora, CentOS, RedHat) and install the following packages:

Warning : Check the package version of CMake (>= 2.8) and Qt (>= 4.5) before installation.

Software OS Version Package Name Debian

Ubuntu build-essential

C++ compilation environment

Ubuntu librrd-dev

RRDTool development files

Red Hat rrdtool-devel

With Debian or Ubuntu

You need to run:

apt-get install build-essential cmake libqt4-dev li brrd-dev

Compilation configuration

At the root of the project directory you'll find a build directory which holds build scripts. Generate the Makefile by running the following command:

- 109 -

tar xzf centreon-broker-2.0.1.tar.gz

cd centreon-broker-2.0.1

cd build

cmake .

CMake will check for all necessary dependencies and indicates if they could not be found.

Variables

Your Centreon Broker can be tweaked to your particular needs using CMake's variable system. Variables can be set like this:

$> cmake -D<variable1>=<value1> [-D<variable2>=<val ue2>] .

Here's the list of variables available and their description:

Variable Description

WITH_PREFIX Base directory for Centreon Broker installation. If other prefixes are expressed as relative paths, they are relative to this path.

WITH_PREFIX_ARCHIVE Path in which development libraries (static libraries) will be installed.

WITH_PREFIX_BINARY Path in which binaries will be installed.

WITH_PREFIX_LIBRARY Where shared objects (like @em cbmod.so) will be installed.

WITH_PREFIX_MODULES Where Centreon Broker modules will be installed.

Example $> cmake -DWITH_PREFIX=/usr/local/centreon-broker -DWITH_PREFIX_LIBRARY=/usr/lib/nagios .

Compilation

Once properly configured, the compilation process is really simple. Just run:

$> make

And wait until compilation completes.

Installation

See the broker installation page.

Installing Centreon Broker

Installation Process

Centreon Broker has multiple components which can be splitted in 5 groups :

• binaries

- 110 -

• Centreon Engine / Nagios modules • Centreon Broker modules • development headers • development libraries

Each of these groups can have a separate installation directory which are configurable as specified in the "Building Centreon Broker" section. Once Centreon Broker has been successfully built, the install process is very simple. Just run the following command as a priviledged user:

$> make install

Packages

Centreon Broker can be packaged directly as a RPM or a DEB package using CPack (part of the CMake software suite). To generate the appropriate package, refer to the @ref build "Building Centreon Broker" section and set the following variables to enable package creation:

• CPACK_BINARY_DEB for Debian package generation • CPACK_BINARY_RPM for RPM package generation

Also note that Merethis provides RPM packages of Centreon Broker using its Centreon Enterprise Server (CES) product.

Pour les installations sur Debian, il faut ajouter la librairie librrd-dev en plus.

Bien noter le résultat du make install pour avoir les chemins qui seront utile par la suite.

Pollers

Dans Configuration -> Centreon -> Pollers : Modifier les champs suivants :

• Centreon Broker configuration path : /etc/centreon (là ou les fichiers .xml seront enregistré) • Centreon Broker modules path : /usr/local/lib/centreon-broker/ (là ou se trouve les fichiers

[0-9][0-9]-*.so)

Nagios.cfg

Dans Configuration -> Nagios -> nagios.cfg, Modifier les champs suivants :

• Multiple Broker Module : /usr/local/lib/cbmod.so /etc/centreon/central-module.xml • Broker Module Options : -1

Export des fichiers de config

Les fichiers de configuration du broker sont exporté en même temps que la config de Nagios. Il faut donc faire :

Configuration du module Centreon-Nagvis Tout d'abord, une chose importante : un compte administrateur de Centreon ne peut pas visualiser la vue Nagvis. Si vous avez une installation flambante neuve, il vous faudra créer un utilisateur standard dans Centreon.

Création des utilisateurs Nous allons créer un utilisateur supervision qui fera partie du groupe de contact niveau1. Celui-ci recevra les autorisations pour la vue Nagvis et l'accès aux ressources. Ce groupe sera limité à la vue dans Nagvis en lecture seule. Un groupe d'accès nagvisRO sera initialisé pour correspondre au groupe Read-Only de Nagvis. Il faudra créer un utilisateur exploitant qui fera partie du groupe de contact niveau2. Ce groupe recevra des autorisations plus importantes telles que les actions d'acquittements des alarmes. En outre, ce groupe aura le droit de modifier la cartographie de Nagvis. Un groupe d'accès nagvisRW sera initialisé pour correspondre au groupe Administrators de Nagvis.

Création du groupe de contact niveau1.

- 287 -

Liste des groupes de contacts

Création de l'utilisateur supervision associé au groupe niveau1

Celui-ci n'est pas administrateur. Faire de même pour l'utilisateur exploitant et son groupe de contact associé niveau2

Liste des utilisateurs

- 288 -

Configuration des ACL de Centreon Maintenant, créez deux groupes d'accès nagvisRW et nagvisRO.

supervision et niveau1 devront être sélectionnés pour le groupe d'accès nagvisRO

exploitant et niveau2 devront être sélectionnés pour le groupe d'accès nagvisRW Nous donnerons accès aux menus de Centreon avec les groupes d'accès aux Menus MNUniveau1 et MNUniveau2.

- 289 -

Le niveau 1 aura une vue limitée au monitoring en temps réel de la supervision. Ne pas oublier d'associer le groupe d'accès nagvisRO.

- 290 -

Le niveau 2 aura une vue plus étendue. Ne pas oublier d'associer le groupe d'accès nagvisRW.

Ensuite nous utiliserons un groupe d'accès aux ressources nommé All Ressources (celui créé par défaut lors de l'installation de Centreon) et nous ajouterons les deux groupes d'accès nagvisRW et nagvisRO.

- 291 -

Pour information, nous créerons le groupe d'accès aux actions pour le niveau2 et nous ajouterons le groupe d'accès nagvisRW. Les actions permises par ce groupe seront cochées dans la liste proposée.

Configuration du mappage Nagvis-Centreon Nos ACL étant créés, nous devons associer chaque groupe d'accès à un groupe de Nagvis. Sélectionnez Configuration -> Nagvis -> ACL

Dans notre exemple le groupe nagvisRO (nagios en lecture seule) sera associé au groupe Users (read-only) et le groupe nagvisRW (admin nagvis) sera associé au groupe Administrators. N'oubliez pas de sauvegarder.

Vérification Et voila, votre module est fonctionnel. Vous pouvez le tester en vous connectant en exploitant. La vue Nagvis est parfaitement intégrée dans l'interface Centreon.

- 292 -

Un conseil, n'oublier pas de changer le mot de passe par défaut de l'administrateur nagiosadmin proposé par Nagvis.

Utilisation des utilisateurs en lecture seule Dernière chose à paramétrer, un utilisateur Nagvis en lecture seule. Si vous vous connectez en supervision sans ce dernier paramétrage vous aurez cette vue ci-dessous.

Cette situation est tout à fait normale, car il n'y a pas de relation entre les utilisateurs Centreon et un utilisateur Nagvis en lecture seule (Il n'existe pas en fait). Pour remédier, se connecter en administrateur (par exemple en exploitant). Sélectionnez le menu User Menu / Manage Users

- 293 -

Créer l'utilisateur supervision ou tout autre nom.

Lui affecter le rôle Users (read-only). N'oubliez pas de sauvegarder et quitter l'interface. Vous pouvez utiliser sans problème le compte supervision. 8.2 syslog

Installation du module Centreon Syslog Frontend Nous allons aborder l'installation du module Centreon Syslog Frontend, celui permet de visualiser les logs du serveur Syslog dans l'interface Centreon. Ce module permet d'effectuer des recherches et/ou des tris selon certains paramètres (date, niveau d'alerte, etc)

Pré requis Il nous faut installer la librairie libssh2 pour la connexion ssh entre le serveur de supervision et syslog, les outils de développement php5. apt-get install libssh2-1-dev php5-dev apt-get install libssh2-php apache2ctl -k graceful pecl install -f ssh2-beta

On récupère la librairie PECL cd /usr/local/src/ wget http://pecl.php.net/get/ssh2-0.11.0.tgz tar xzf ssh2-0.11.0.tgz cd ssh2-0.11.0

- 294 -

Il faut compiler le module ssh pour php phpize && ./configure --with-ssh2 && make

Copier le module dans php5 cp modules/ssh2.so /usr/lib/php5/20060613+lfs

On doit faire prendre en compte cette librairie par le serveur apache echo "extension=ssh2.so" > /etc/php5/cli/conf.d/ssh 2.ini echo "extension=ssh2.so" > /etc/php5/apache2/conf.d /ssh2.ini

Redémarrer le serveur apache /etc/init.d/apache2 restart

Vérifions l'activation de ssh2 php -i |grep ssh Registered PHP Streams => zip, php, file, data, htt p, ftp, compress.bzip2, compress.zlib, https, ftps, ssh2.shell, ssh2.exec, ssh2.tunnel, ssh2.scp, ssh2. sftp ssh2 libssh2 version => 0.18 banner => SSH-2.0-libssh2_0.18

Installation en mode ligne de commande sur le serve ur de supervision Vous devez récupérer les binaires sur le site de Centreon.(authentification obligatoire) cd /usr/local/src tar xzf centreon-syslog-frontend-1.3.3.tar.gz cd centreon-syslog-frontend-1.3.3 ./install -i

L'installation en ligne de commande est terminée

Installation du module dans Centreon Il faut se connecter à l'interface Web de centreon

- 296 -

Sélectionnez Administration / Modules. Cliquez sur l'icône à droite pour installer le module.

Cliquez sur le bouton Install Modules

L'installation s'est bien passée, cliquer sur le bouton back.

- 297 -

L'installation du module est terminée, vous pouvez accéder à sa configuration.

Une nouvelle vue Syslog a été créé dans la section Monitoring, mais celle-ci n'est pas encore fonctionnelle. Il faut configurer l'authentification ssh entre le serveur de supervision et le serveur syslog.

Configuration du module Avant de réaliser la configuration du module, affectez un mot de passe à l'utilisateur syslog sur le serveur Syslog. root@syslog:~# passwd syslog Entrez le nouveau mot de passe UNIX : syslog2011 Retapez le nouveau mot de passe UNIX : syslog2011 passwd : le mot de passe a été mis à jour avec succ ès

Sélectionnez Administration / Modules.

- 298 -

Cliquez sur Configuration

Cliquez sur Modify pour modifier la configuration

Onglet Database : Saisir l'adresse IP du serveur Syslog, le nom de la base Syslog et le mot de passe syslogadmin

Onglet SSH : Saisir l'adresse IP du serveur Syslog, le mot de passe de l'utilisateur syslog

Onglet Configuration : Saisir le chemin du fichier de configuration de syslog sur le serveur Syslog. Sauvegarder la configuration en cliquant sur le bouton Save.

Il faut exporter le fichier de configuration vers le serveur Syslog. Cliquer sur le bouton Export Configuration

- 300 -

Le fichier a bien été envoyé. Attention, il y a un problème de configuration dans la connexion Mysql que je n'arrive pas à expliquer actuellement. Remettre l'adresse ip du serveur Syslog dans l'onglet Database.

Sauvegarder la configuration sans l'exporter. Retour à la vue Monitoring, il n'y a toujours pas de données affichées ! En fait le serveur Mysql de Syslog n'accepte pas les connexions externes. Il faut donc modifier le fichier de configuration my.cnf du serveur Syslog. bind-address = 172.16.209.132

Modifier le paramètre bind-address et relancer le serveur Mysql /etc/init.d/mysql restart

- 301 -

Cliquez sur Monitoring / Syslog. Vous avez vos messages syslog.

Cliquez sur Search, vous avez un message d'erreur. C'est un fonctionnement normal. La table des logs de la journée actuelle n'est pas encore présente. Il faudra attendre 23 h 59 pour que le script /usr/bin/syslog/tableLogRotate.php s'exécute. Il y a possiblité de forcer son exécution en se connectant sur le serveur Syslog. root@syslog:/usr/bin/syslog# php tableLogRotate.php BEGIN TABLES LOGS ROTATION AT 2011-05-06 15:53:10 DROP TABLE all_logs RENAME TABLE logs TO logs20110507 CREATE TABLE logs CREATE MERGE TABLE all_logs

- 302 -

END OF TABLES LOGS ROTATION AT 2011-05-06 15:53:10 BEGIN TABLES CACHE ROTATION AT 2011-05-06 15:53:10 DROP TABLE all_cache RENAME TABLE cache TO cache20110507 CREATE MERGE TABLE all_cache END OF TABLES CACHE ROTATION AT 2011-05-06 15:53:10

La table est créée, vous pouvez retourner sur Centreon et visualiser les logs.

Vous avez la possibilité de filtrer sur une période de date et d'exporter au format csv ou open office.

Mise en place de la coloration syntaxique des événe ments Pour bénéficier de la coloration des événements en fonction de leur criticité, nous devons modifier le fichier de configuration de Rsyslog. Cette modification permettra d'afficher au format texte, les champs Facility et Severity. Editez le fichier /etc/rsyslog.conf et modifiez l'avant dernière ligne comme ci-dessous. $template sysMysql,"INSERT INTO logs (host,facility , priority,level,tag,datetime,program,msg) VALUES ('%HOSTNAME%','%syslogfacility-text%','%sysl ogpriority-text%','%syslogseverity%', '%syslogtag%', '%timereported:::date-mysql%','%prog ramname%', '%msg%')", SQL

Nous rajoutons le suffixe -text aux champs syslogfacility et syslogpriority. N'oubliez pas de relancer le serveur syslog. /etc/init.d/rsyslog restart

- 303 -

Les champs se remplissent aussitôt avec du texte, le champ Severity change de couleur en fonction de la criticité de l'événement comme ci-dessous.

L'installation de notre Syslog est terminée. Pour effectuer une éventuelle mise à jour du module, visiter cette page. Il restera à compléter l'installation du module de langue français. Nous allons, maintenant, aborder la centralisation des événements windows par l'intermédiaire de Centreon E2S. 8.3 geolocation
