Installation Centreon MBI (Licence commerciale)

Bonjour,Nous utilisons Centreon 23.10.11 (Bientôt 24.04.XX), dans un environnement Redhat 8.Nous envisageons d’installer un nouveau serveur MBI (Centreon Bi Reporting Server) avec sa base de donnée Mariadb (Donc 1 seul nouveau server)J’aimerais avoir un retour d’expérience sur ceux qui ont déjà fait ça … et surtout:Avez vous rencontré des soucis lors de l’Ajout du serveur MBI dans votre infra de Prod existante ?Genre: Problème de crash de la base ou d’indispo du Central Web ..… ?A la base on m’avait conseillé de créer une nouvelle infra de POC identique à la Prod puis de relier le nouveau serveur MBI dessus … puis une fois validé: brancher le serveur MBI sur l’infra existante…. mais tout ça me semble compliqué et trop long….Surtout que la Doc me semble bien faite : https://docs.centreon.com/fr/docs/reporting/installation/ Merci pour vos retours,Cdt

Restart of a poller and synchronization of the current downtimes

Hi,When a poller has just been restarted, both querying the API or looking at the UI, one can see there is no downtime for some particular objects. The fact is, there is a downtime actually, but it doesn’t appear before a few time (around a couple of minutes).When some external tools relay on the presence of a downtime to take some decision, restarting a poller may lead to some issue (and sometime a simple reload isn’t sufficient).I wonder if some other people have also experienced this behaviour, and if it could be possible for Centreon not to indicate the absence of a downtime before it is not fully updated (hence with a 100% reliability)?Sorry if I’m unclear, please ask for some clarification if this isn’t the case.

reverse high avaiability done by a " centreon expert "

hello,in the start of the year , an expert was mandated for our client to make his centreon clean . Right from the start , he make the high avaibility cluster on the qualification side ..He made it with mysql 1.3 instead of 1.5 ( for some reason the repository for mariadb 1.5 , install the 1.3 version). He should have stop here , the prerequisite of mysql 1.5 was not meet. but he did it anyway. He was let go before ending his work and didnt revert what he did. Today i cant upgrade , it ask me to upgrade mysql but i cant ( always the same not resolved issue with the repo ) . We try to use a save from all of the servers but the change where already in place , and we cant go on last year because we switch from centos to redhat on january. I cant revert the dnf install of the update. I tried to reverse the HA , but it dont work. How can i reverse the HA , to not be in cluster anymore like it was before , and reuse the DB that was in place before ( and with the good mysql version ) ? Thanks

ACL issue - no ressource showed

Hello,I have an issue regarding ACL. I wanted to restrict the ressource view to some users.For information I run a fresh 24.04.07 centreon installation made on a debian 12.Here what I’ve done (following the documentation) :Creation of a “Ressource Access” ACL On tab “Hosts resources” I’ve checked only the host I wanted to display and leave everything by default On tab “Services Resources” I’ve checked “Include all servicegroups” I leave the others tab as default Creation of a “Menu access” ACL I only checked “Home”, “Monitoring” and “Reporting” Creation of a “Action Access” ACL I duplicated the existing “Simple User” ACL and removed some actions like Enable/Disable Notification … I just wanted the users to have a display access. Finally I created an “Access Group” linked with a test user and in the “Authorizations information” tab I selected the 3 ACL I just created.When I log on with my user display limitation are OK but I don’t see any hosts or services.I tried a lot of different

envoi de notification par mail vers une personne d'astreinte en plus des notifications courantes.

Bonjour Je cherche une manière “élégante” de mettre en place des notification vers une personne d’astreinte (de garde) en plus des notifications autres : nous envoyons un mail sur une boite mail qui est transformé en appel téléphonique. contexte : astreinte en heure non ouvrée (mais ce n’est pas grave si il y a aussi des appels en heures ouvrées)Centreon 23.04 Nous utilisons déjà les notifications en journée. Nous avons des sites qui nécessitent une astreinte et d’autre non (groupes d’hôtes différents) Nous avons des services qui nécessitent une astreinte et d’autre non (groupes de services différents et criticités différentes)J’ai essayé 2 méthodes :Mettre le destinataire d’astreinte sur un modèle de service laborieux au niveau paramétrage et donc source d’erreur Mettre une escalade laborieux au niveau paramétrage et donc source d’erreur dans ce cas si on fait l’escalade à la première notification alors la notification normale ne part pas et est remplacée par la notification d’esca

Force check wont work since update

Hi everyone,Since the last update I can’t use force check on my hosts/services + I need to restart centengine everytime I add a new host in order to make it appear on Centreon.I use the IT-100 license. Gorgoned is not starting because of this error (below), I did some research but can’t find any solution on how to install this FFI::Platypus module (seems to be a Perl module). Is this why there is a problem on the force checks?Hope someone has a solution to my problem ! :) Have a good day and thank’s for reading ;)

Error ACL management

Hello everyone,Since upgrading to 24.04.7, I have a problem with ACL management.My non-admin users no longer see the service groups in the detailed services or in the custom views.If I set my user as administrator, I can see the service groups. I've looked at the acl management and resource access is set to all.For testing purposes, I gave my user full rights (he has access to all) but the list of group services remains empty. I've checked that my user is in the right rights group. When I want to reload the ACLs, I get an error message. Thanks for your help
