Installing Centreon MAP extension

As MAP (Legacy) will not evolve anymore, we suggest you install Centreon MAP instead. MAP has significant advantages compared to MAP (Legacy) including:

  • Web editor: Create and edit your views directly from your web browser.
  • New server: Brand new server and data model providing better performance.

Centreon MAP requires a valid license key. To purchase one and retrieve the necessary repositories, contact Centreon.

This chapter describes how to install Centreon MAP. The server must be installed on a dedicated machine to allow Centreon MAP to operate with its own database and avoid any potential conflict with the Centreon central server.

Before installation, be sure to review the Prerequisites chapter for system requirements (CPU and memory). Remember to choose the best type of architecture to suit your needs.

Architecture​

Centreon MAP consists of three components:

  • Centreon MAP Server, developed in Java, using SpringBoot, Hibernate and CXF
  • Centreon MAP Web interface, developed in Javascript, based on Backbone.js
  • Centreon MAP Desktop Client, developed in Java, based on Eclipse RCP 4.

The diagram below summarizes the architecture:

Prerequisites​

Centreon​

The central server and Centreon MAP must be installed in the same major versions (i.e. both in 22.04.x).

Centreon MAP Server​

License​

The server requires the license to be available and valid on Centreon's central server. To do this, you must contact the support Centreon support team to get & install your license key.

Hardware​

Hardware requirements for your dedicated Centreon MAP server are as follows:

Monitored services< 10 000< 20 000< 40 000> 40 000
CPU2 vCPU ( 3Ghz ) minimum4 CPU (3GHz) Minimum4 CPU (3GHz) MinimumAsk Centreon Support
Dedicated Memory2GB4GB8GBAsk Centreon Support
MariaDB data partition2GB5GB10GBAsk Centreon Support

To correctly implement the dedicated memory, you have to edit the JAVA_OPTS parameter in the Centreon Map configurations file /etc/centreon-studio/centreon-map.conf and restart the service:

JAVA_OPTS="-Xms512m -Xmx4G"

The Xmx value depends on the amount of memory indicated in the above table.

Then restart the service:

systemctl restart centreon-map

The space used by Centreon MAP server is directly determined by the number of elements you add into your views. An element is any graphical object in Centreon MAP. Most elements (like hosts, groups, etc.) have children which must be included in the count.

These values are applied after optimization of Centreon MAP tables.

Software​

See the software requirements.

Information required during configuration​

  • Centreon Web login with admin rights.

Even with a correctly sized server, you should have in mind the best practices & recommendations when creating views so you don't face performance issues.

If the central server is configured in HTTPS, you must apply the SSL configuration on the MAP server. Follow this procedure to secure your MAP server.

Centreon MAP Web interface​

License​

The web interface requires the license to be available and valid on Centreon's central server. To do this, you must contact the support Centreon support team to get & install your license key.

Compatibility​

The Centreon MAP Web interface is compatible with the following web browsers:

  • Google Chrome (latest version at the time of Centreon software release and above). Please visit the Google Chrome FAQ for a description of the Chrome support policy.
  • Mozilla Firefox (latest version at the time of Centreon software release and above). Please visit the Mozilla FAQ for a description of the Firefox support policy.
  • Apple Safari (latest version at the time of Centreon software release and above)
  • Microsoft Edge Chromium (latest version at the time of Centreon software release and above)

If an update to those supported browsers was to cause an incompatibility, Centreon would work on a fix in the shortest possible time (for supported Centreon versions). Though other browsers may work, Centreon will not attempt to resolve problems with browsers other than those listed above.

Your screen resolution must be at least 1280 x 768.

Centreon MAP Desktop Client​

  • 4 GB of RAM minimum, 8 GB advised (mandatory for 10,000 or more services)
  • Java 64 bits version 8
  • Resolution must be at least 1280 x 768.
  • Debian 7,8 or 9

Desktop Client is not compatible with Microsoft Windows Server. * If a version of Java other than 8 is installed, consider installing Java 8 and modifying Centreon-Map4.ini to add the following line -vm $path_to_java8$ BEFORE -vmwargs.

To optimize the desktop client, you have to "give" it more memory than the default value. Modify the following file:

C:\Users\<YOUR_USERNAME>\AppData\Local\Centreon-Map4\Centreon-Map4.ini

And add the following lines at the end of the file, on a new line:

-Xms512m
-Xmx4g

Network requirements​

Centreon MAP Server machine must access:

  • Centreon Central broker, usually on Centreon Central machine, using TCP port 5758
  • Centreon Database, usually on Centreon Central machine, using TCP port 3306
  • Centreon MAP database, usually on localhost, using TCP port 3306.

All the ports above are default values and can be changed if needed.

  • Centreon Web Central, using HTTP port 80 or HTTPS port 443

Centreon MAP Desktop Client machines must access:

  • Centreon MAP Server, using HTTP port 8080 or 8443 when HTTPS/TLS is enabled
  • Internet with or without proxy.

Ports 8080 and 8443 are recommended default values, but other configurations are possible.

Server installation​

Centreon Web interface​

You must provide to Centreon MAP server a dedicated user who has access to all resources through the appropriate access list groups. Since the password will be stored in human-readable form in a configuration file, you should not use a Centreon admin user account.

Provide this user with access to the Centreon Web real-time API:

image

Exclude the user from the password expiration policy on page Administration > Authentication: their password will never expire.

image

Centreon Central server​

Create a user in the mysql instance hosting 'centreon' and 'centreon_storage' databases:

CREATE USER 'centreon_map'@'<IP_SERVER_MAP>' IDENTIFIED BY 'centreon_map';
GRANT SELECT ON centreon_storage.* TO 'centreon_map'@'<IP_SERVER_MAP>';
GRANT SELECT, INSERT ON centreon.* TO 'centreon_map'@'<IP_SERVER_MAP>';

The INSERT privilege will only be used during the installation process in order to create new Centreon Broker output. It will be revoked later.

Centreon MAP (Legacy) server​

Java version requirement​

Ensure a version of Java 17 (or 18) is installed before you start the procedure.

  • If you need to check the Java version, enter the following command:

    java -version
  • If you need to upgrade the Java installation to Java 17 (or 18), go to the Oracle official download page.

  • If several Java versions are installed, you need to activate the right version. Display the installed versions using the following command and select the Java 17 (or 18) version:

    sudo update-alternatives --config java
  • If you need to use your platform in HTTPS, you will have to generate a keystore file for the Java 17 (or 18) version (see the procedure).

Procedure​

If you installed your Centreon MAP server from a "fresh OS installation" you need to install the Centreon repository:

dnf install -y dnf-plugins-core
dnf config-manager --add-repo https://packages.centreon.com/rpm-standard/22.04/el8/centreon-22.04.repo

If the URL doesn't work, you can manualy find this package in the folder.

Install Centreon Business repository, you can find it on the support portal.

Then install Centreon MAP server using the following command:

dnf install centreon-map-server

When installing Centreon MAP server, it will automatically install java (OpenJDK 11) if needed.

You need to have a MariaDB database to store Centreon MAP data, whether it's on localhost or somewhere else.

To install MariaDB, execute the following command:

dnf install MariaDB-client MariaDB-server

Configuration​

Make sure the database that stores Centreon MAP data is optimized (automatically added by the RPM in /etc/my.cnf.d/map.cnf):

max_allowed_packet = 20M
innodb_log_file_size = 200M

Then, restart MariaDB:

systemctl restart mariadb

Secure the database​

Since MariaDB 10.5, it is mandatory to secure the database's root access before installing Centreon. If you are using a local database, run the following command on the central server:

mysql_secure_installation
  • Answer yes to all questions except "Disallow root login remotely?".
  • It is mandatory to set a password for the root user of the database. You will need this password during the web installation.

For more information, please see the official MariaDB documentation.

Configure.sh script​

Execute the Centreon MAP server configuration script. Two modes are available: interactive or automatic.

  • interactive (no option/default mode): Several questions will be asked to interactively fill in the installation variables.
  • automatic (--automatic or -a): The installation will be done automatically from the values set in /etc/centreon-studio/vars.sh file

If it's your first installation, we advise you to use the standard mode (interactive) and choose No when asked for advanced installation mode:

/etc/centreon-studio/configure.sh

The output should look like this:

Configuration completed, enjoy !

This script generates the studio-config.properties file.

Custom URI​

If you have customized the URI for your Centreon platform, you need to edit the studio-config.properties file by adding the following command using the custom URI already defined here:

centreon.path=/your-custom-uri

Then restart the centreon-map service:

systemctl restart centreon-map

Central server​

Before restarting Broker you must export the configuration from the Centreon Web interface.

Restart Centreon Broker on the Central server:

systemctl restart cbd

Remove the INSERT privilege from user centreon_map:

REVOKE INSERT ON centreon.* FROM 'centreon_map'@'<IP_SERVER_MAP>';

Centreon MAP server​

Check your configuration:

/etc/centreon-studio/diagnostic.sh

If configuration is correct, the centreon-map service can be started from the Centreon MAP server:

systemctl restart centreon-map

Enable the service to start up automatically on server boot:

systemctl enable centreon-map

Centreon Map server is now started and enabled, let's install the interface part of the extension.

Web Interface installation​

Central server​

Install Centreon Business repository, you can find it on the support portal.

Then execute the following command:

dnf install centreon-map-web-client

Web​

Go to Centreon > Administration > Extensions and click on the install button:

  • License Manager (if not yet installed)
  • Map Web Client

Upload the license map.license given by the support team. Refresh the page and the banner must be green with the valid license date.

Desktop Client​

Executables​

The desktop client is currently available only for 64-bit Windows, Mac and Linux platforms (Debian and Ubuntu).

You can find the installers in Monitoring > Map > Desktop Client or here.

For performance considerations, we highly recommend to have less than 5, 10 users maximum connected at the same time manipulating views.

Installation​

On user's computer​

The desktop client requires Java 8. You can download and install the latest version of Java from here.

Be sure to download the 64-bit version. Browsers are usually 32-bit and the Oracle website generally proposes 32-bit Java instead of the 64-bit version. If you already have Java installed, use the java -version command to check the architecture. If 64-bit does not appear, the version is 32-bit.

On a Mac platform, note that you must install Oracle JDK instead of the usually-required JRE.

To check the Java version run the command:

java -version

Execute centreon-map4-desktop-client-xxxx.exe:

You do not need to be the administrator of your computer to perform the installation. All the files are will be installed in your personnal folders.

The default installation folder is C:\Users\$user$\AppData\LocalCentreon-Map4.

You can install the software at this location without administrator rights but can change the destination to Program files if you have the sufficient rights.

Use the installer to install the software properly and integrate it into the Windows environment. The installer can also be used to uninstall it from the Windows dedicated configuration page.

Updates​

Once installed, the Desktop Client is automatically kept up to date through an online update system. When it connects to a Centreon MAP server it automatically downloads and installs the latest version compatible with the server. Auto-update requires your computer to have internet access.

Secure your platform​

Don't forget to secure your Centreon platform following our recommendations
