Important change on 21.10 package repository

As you probably already know, Centreon 21.10 is not a supported version anymore (more information here).As a consequence, the RPM package repository for this version has been archived: it moved from https://packages.centreon.com/rpm-standard/21.10 to https://archives.centreon.com/standard/21.10.If your platform is still running 21.10 and you need to update it, please update your YUM or DNF repository configuration to handle this change.

Dés-enregister un poller suite à erreur sur le nom

Salut,J’ai enregistré un poller sur un cenral mais je mes suis trompé dans le nom que je devais lui donner. Si je tente de refaire la manipulation avec le bon nom il me dit qu’un poller avec cette IP est déjà connu et il semblerait quðil n’y ai pas d’option pour annuler le premier enregistrement.Je commençais à regarder en BDD voir si et où je pouvais agir mais je ne voudrais pas tout péter.Il y a un moyen moins bricolage pour faire ça ? Et s’il faut éditer directement en base : c’est quelle(s) table(s) précisément ?EN: How do I revert the action of adding a poller via the script registerServerTopology.sh? So I would be able to add the same one again but with with the right name.

Remove hosts from probe that does not exist

Hi,I have an issue - poller went down permanently before I was able to remove them from monitoring. So now they are in the main view all the time. How do I remove them? I found a topic: but there is no good explanation how to remove them from monitoring properly, without causing any new issues after deleting hosts from SQL?

Can't export poller after 'PATCH' a host

Hi everyone, I’m running 24.04, and try to use the APIv2 to maintain some HostGroup to Host by script.I can do what I want, but maybe I have a ‘bug’:I use a command method ‘PATCH’ to update a single Host configuration, by modifying only the ‘groups’ item (by passing an array of integer (of HostGroup ID)).https://docs-api.centreon.com/api/centreon-web/24.10/#tag/Host/paths/~1configuration~1hosts~1%7Bhost_id%7D/patchThat work like a charm BUT, after doing that, I can’t export poller configuration anymore.It seems like this command add a ‘null’ value to Host Categories:After that if I go to the host configuration, clic the cross to ‘delete’ host category (but in fact, there is none), and save. Then I can export poller configuration again.Does someone have a way to update only ‘groups’ for a ‘host’ ?
