Centreon Map Server¶
Find below the hardware pre-requisites for your dedicated Centreon Map 4 server :
|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 use the dedicated memory, you have to edit the JAVA_OPTS parameter in the tomcat configurations file /etc/tomcat/tomcat/tomcat.conf and restart the service :
JAVA_OPTS="... -Xms512m Xmx4Go"
NB: The Xmx value depends on the amount of memory corresponding to 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 of elements (like hosts, groups, etc.) have children which must be included in the count.
These values are taken after optimizing the tables of Centreon Map.
|OS||CentOS 7 / Redhat 7|
|Java||8 (installed automatically)|
|Tomcat||7 (installed automatically)|
Else you can use any other GNU/Linux operating system as long as you can install MariaDB, Java and Tomcat 7 minimum.
Information that will be required during configuration
- Centreon Web login with admin rights
Centreon Map 4 Web Client¶
The Centreon Map web client is compatible with the following list of web browser:

- If another version of Java than 8 is installed, please 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 :
NB: The Xmx value is the MAX memory used by the application. i.e: if your computer has 4Go RAM, set this value to 3GB maximum. (or 75% of the maximum)
*Regarding your OS, the file is located here
- WINDOWS: C:[USER][AppdatalocaleCentreon-map4unstableCentreon-Map4.ini
- LINUX: /opt/centreon-map4-desktop-client/Centreon-Map4.ini

In order to be able to use Centreon Map, you need to retrieve a license file.
To generate it, 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 RPM and is available on the Centreon repository.
Install the Centreon Fingerprint binary.
# yum install centreon-fingerprint
Execute Centreon Fingerprint
The machine fingerprint will be displayed in the console.
You will have to provide it to Centreon Support that will generate the license file you need to use Centreon Map Server. If you already have the license, we’ll show you how to install it while installing the Centreon Map server in the next chapter.
