You want to create a new module for Centreon or to adapt an existing one? You're at the right place!
An empty module template can be found inside Centreon's repository
NOTE: Main documentation is directly stored in the dummy repository
You should know Centreon contains a page dedicated to the installation and the uninstallation of modules
(Administration > Extensions > Manager). To make the module appears on this page, its directory must be placed inside
modules/ directory. Example:
The essential elements your module's directory must contain are presented below:
$module_conf['dummy'] = [ // Short module's name. Must be equal to your module's directory name 'name' => 'dummy', // Full module's name 'rname' => 'Dummy Example Module', // Module's version 'mod_release' => '21.04', // Additional information 'infos' => 'This module is a skeleton', // Allow your module to be uninstalled 'is_removeable' => '1', // Module author's name 'author' => 'Centreon', // Stability of module. 'stability' => 'stable', // Last time module was updated. 'last_update' => '2020-12-01', // Release notes link, if any. 'release_note' => 'https://docs.centreon.com/current/en/releases/centreon-os-extensions.html', // Images associated with this module. 'images' => [ 'images/centreon.png', ], ];
[php > install.php]
This PHP file is executed at module installation if it is configured inside the conf.php file.
[php > uninstall.php]
This PHP file is executed at module uninstallation if it is configured inside the conf.php file.
[sql > install.sql]
This SQL file is executed during the module installation if it is configured inside the conf.php file. If you want
your module to be available from Centreon menus, you must insert new entries into the
topology table of the
centreon database. An example is available inside the
[sql > uninstall.sql]
This SQL file is executed during the module uninstallation if it is configured inside the conf.php file. It can also remove your module from Centreon menus.
[generate_files > *.php]
The PHP files contained inside the
generate_files directory will be executed during the monitoring engine
configuration files generation (inside Configuration > Monitoring Engines). Those files must generate configuration
[UPGRADE > dummy-x.x > sql > upgrade.sql]
Centreon provides an upgrade system for modules. To use it, just add a directory under
UPGRADE named using the
<module name>-<version>. When clicking on the upgrade button, Centreon will search for scripts
to execute, following the logical order of versions.
For example, if the version 1.0 of the dummy module is installed and the following directories exist:
ls UPGRADE dummy-1.1 dummy-1.2
Centreon will execute the scripts in the following order : 1.1, 1.2. A configuration file in each upgrade directory is present in order to allow (or not) the execution.
You're free to organize the remaining files (your module's content) as you like.

That's great, you know how to install a module! As an empty module is not really useful, put your imagination at work. Knowing that you can do almost everything, it should not be too complicated :-).
Connecting to the database
You can use the
centstorage databases by calling the following file:
For example, execute requests like this:
$pearDB = new CentreonDB(); $pearDB->query("SELECT * FROM host");
You can access most of the functions already developed within Centreon using
include() statements. They're generally
Before developing your own function, check the existing code, it could spare your time!
