Prerequisites¶

Centreon¶

The required version of Centreon software for compatibility with Centreon MAP is as follows:

Software	Version
Centreon Web	18.10
Centreon Broker	18.10
Centreon BAM (Optional)	18.10

Centreon must be installed using the RPM packages.

Centreon MAP Server¶

Hardware

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

Monitored services	< 10 000	< 20 000	< 40 000	> 40 000
CPU	2 vCPU ( 3Ghz ) minimum	4 CPU (3GHz) Minimum	4 CPU (3GHz) Minimum	Ask Centreon Support
Dedicated Memory	2GB	4GB	8GB	Ask Centreon Support
MySQL data partition	2GB	5GB	10GB	Ask Centreon Support

To correctly implement the dedicated memory, you have to edit the JAVA_OPTS parameter in the Tomcat configurations file /etc/tomcat/tomcat.conf and restart the service:

JAVA_OPTS=" -Xms512m -Xmx4G"

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

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.

Note

These values are applied after optimization of Centreon MAP tables.

Software

Software	Version
OS	CentOS 7 / Redhat 7
DBMS	MariaDB 10.1
Java	8 (installed automatically)
Tomcat	7 (installed automatically)
Firewall	Disabled
SELinux	Disabled

Information required during configuration

Centreon Web login with admin rights.

Centreon MAP Web Client¶

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

Firefox (latest version)
Chrome (latest version)
Safari (latest version).

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.

Note

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. To do so, modify the Centreon-Map4.ini* file and add the following parameters:

-Xms512m
-Xmx4Go

Note: The Xmx value is the maximum memory used by the application (i.e, if your computer has 4 Go RAM, set this value to 3GB maximum (or 75% of the maximum).

*Depending on your OS, the file is located in one of this directories:

WINDOWS: C:[USER][AppdatalocaleCentreon-map4unstableCentreon-Map4.ini
LINUX: /opt/centreon-map4-desktop-client/Centreon-Map4.ini

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 TCP port 8080 or 8443 when SSL is enabled
Internet with or without proxy.

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

License¶

A license file is required in order to use Centreon MAP.

To generate the license, we need the fingerprint of the machine on which Centreon MAP server is installed. The fingerprint is generated using Centreon Fingerprint which is packaged in the RPM and available in the Centreon repository.

Install the Centreon Fingerprint binary version.

# yum install centreon-fingerprint

Run Centreon Fingerprint

# centreon-fingerprint

The machine fingerprint will be displayed on the console.

After you provide the fingerprint to Centreon Support, it will generate the license file you require to use Centreon MAP Server. If you already have a license, we will explain in the next chapter how to install it while installing the Centreon MAP server.
