How to compile centreon-collect 22.10.0 from source?

Hello everyone,I am currently trying to compile centreon-collect 22.10.0 from source, with no success so far.Could you please provide the information related to the environment you use to compile centreon-collect 22.10.0? What are the Pre-requisites? Do you plan to publish a full documentation about how to install a poller from source? Here I share the list of all actions tried and all the errors encountered (so far): The first approach is to look for the official documentation (https://docs.centreon.com/). However, no information is provided about how to install a poller from source. The only process available explains how to install a poller using packages. The second approach taken was then to try compiling centreon-collect 22.10.0 on a CentOs7; following the readme file contained in the source, using the tarball available on https://download.centreon.com/.       wget https://s3-eu-west-1.amazonaws.com/centreon-download/public/centreon-collect/centreon-collect-22.10.0.tar.g

Changement des couleurs dans l’interface

Hi,Is it possible to change the color used for the banner and the menu, which is currently blue?We have two Centreon environments, one is our production environment, the other is a integration/test environment. We’d like to have a different color for the top banner and the menu to help distinguish the two to prevent potential human errors.

Export hosts and services to file

Hi,I would like to export hosts and services from centreon to a file. There is an option in the menu. I only choose hosts and services but there is a problem. I have several groups of hosts where standard services are connected (c drive, cpu, memory, etc.). It is convenient because I do not have to set up these services every time, but these services are created automatically.But these services are omitted from the export. has anyone had a similar problem? I tried to make a sql query in the database but it doesn't quite work.
