A list of all installable modules (depending on the registered licence) can be found in the openITCOCKPIT front end under "Administration / Package Manager".
To install a module, simply click on the Install button for the given module. This will open a light box, install the corresponding module and display information about the steps to be performed..
In older versions of openITCOCKPIT < 3.0.10-7 the openitcockpit-update command must be executed from the console after a module has been installed.
Installing modules often includes new rights for openITCOCKPIT users. These rights must be activated for the desired role under "Administration / Manage User Roles" for the module to be usable.
