The required version of Centreon software for compatibility with Centreon MAP is as follows:
|Centreon BAM (Optional)||18.10|
Centreon must be installed using the RPM packages.
Centreon MAP Server¶
To retrieve a license, you’ll need to send a unique number, called “fingerprint” to Centreon support. To do so you need “centreon-fingerprint” binary.
To install it, you need the following repository on your Centreon Map server:
#yum install http://yum.centreon.com/standard/19.04/el7/stable/noarch/RPMS/centreon-release-19.04-1.el7.centos.noarch.rpm
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.
These values are applied after optimization of Centreon MAP tables.
|OS||CentOS 7 / Redhat 7|
|Java||8 (installed automatically)|
|Tomcat||7 (installed automatically)|
Information required during configuration
- Centreon Web login with admin rights.
Even with a correctly sized server, you should have in mind the best practices & recommandations when creating views so you don’t face performance issues. (More information here)
Centreon MAP Web interface¶
The Centreon MAP Web interface 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.
- 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:
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
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.
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
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.
