!-->Followed https://docs.centreon.com/docs/installation/installation-of-a-central-server/using-virtual-machines/ to install the latest 25.10 Alma OVA on an ESXi 6.7 host. Had to manually start the VM, root login & setup seemed to work. Login to web UI also worked ... except I ended up right in the main interface, never got to see the install wizard. I guess I can poke around and manually apply all the things the wizard does. But isn't there a way to force an initialization from scratch? I have already re-run the OVA install with the same result. It looks a bit fishy as it doesn’t ask for any parameters, but just dumps a minimally sized VM with DHCP.

Here is the English translation of your text:---I have installed Centreon version 25.10.9 on a Red Hat 8 operating system. I am using the open-source edition. The server IP is 192.168.1.100. I added a poller with the IP 192.168.1.101. This poller encountered a failure, so I completely reinstalled it on a virtual machine, keeping the IP address the same as 192.168.1.101. The OS is still Red Hat 8. I successfully registered the poller to the server, but when I check the web interface under Configuration > Pollers, it shows that this poller is not running.The poller's log file at /var/log/centreon-gorgone/gorgoned.log contains the following errors:```2026-04-26 21:04:39 - ERROR - [core] unknown identity: proxy-1-2-bdaf280f86b038d7ec34c7862026-04-26 21:04:39 - ERROR - [core] unknown identity: obGRGh1cHuwvZPYCNdVpwH1UrOVxYCUbbSSp4CF2oxc=2026-04-26 21:04:39 - ERROR - [core] unknown identity: proxy-1-2-bdaf280f86b038d7ec34c7862026-04-26 21:04:39 - ERROR - [core] unknown identity: obGRGh1cH

Hi,I recently updated to version 24.10.15 from 24.10.14I also updated some third party plugins at the same time.Since that update I have had the problem that occassionally the services running the plugins (Dell iDRAC among others) are timed out after a while. Could be every other hour or after a day or two.All services using those plugins are moved to “Unknown” with information “(Process Timeout)”Restarting the poller in the GUI solves the problem but why is this happening and any solution?Running the same plugin in the CLI works without any problems so it seems to be a poller issue. OK: All 2 components are ok [2/2 psus]. | 'PSU1#hardware.powersupply.power.watt'=200W;;;0; 'PSU2#hardware.powersupply.power.watt'=180W;;;0; 'hardware.psu.count'=2;;;;Checking poer suppliespower supply 'PSU1' status is 'ok' [instance: 1.1] [value: 200]power supply 'PSU2' status is 'ok' [instance: 1.2] [value: 180]

Est-il possible d’utiliser le magasin d’autorités de certification Windows plutôt que de devoir spécifier un chemin vers un fichier de certificat en dur ?Les autorités de certification étant déjà déployées sur mes serveurs via des GPO, il serait pertinent de pouvoir s’appuyer sur ce mécanisme existant plutôt que de maintenir des fichiers séparés.  Is it possible to use the Windows Certification Authorities store instead of specifying a hard-coded path to a certificate file?Since the certification authorities are already deployed to my servers via Group Policy, it would make sense to leverage this existing mechanism rather than maintaining separate certificate files.

Hello,I’m facing an issue with discovery jobs stuck in Running state on my Centreon platform.Context Multiple discovery jobs configured per poller Providers used: VMware (ESXi & VM discovery, ~20 jobs with filters) AWX (2 jobs: pre-prod and prod) Pollers are sized according to Centreon recommendations Jobs are scheduled sequentially with intervals, running once per day IssueRecently, some discovery jobs are getting stuck in Running state indefinitely. On the central server, I get errors indicating that the job cannot be launched because it is already in Running state It is impossible to restart the job from the UI (even after waiting a long time and after restarting gorgoned service ) Checks already performed Reviewed gorgoned logs on central and pollers Checked VMware daemon logs on pollers No explicit errors found explaining the blockage Verified that jobs are not overlapping by design (sequential scheduling) Observations The issue appeared recently (no maj

Voici une version adaptée intégrant ce contexte : Bonjour à tous,Nous supervisons actuellement des conteneurs OpenVZ avec Centreon.Nous disposons d’un ancien plugin “fait maison” qui permet de contrôler l’état des conteneurs (notamment la partie démarrage), mais il commence à dater et nous souhaitons savoir s’il existe aujourd’hui une méthode plus standard / officielle pour superviser correctement cet aspect.Notre besoin est de : Détecter un échec de démarrage d’un conteneur Vérifier que le conteneur est réellement en état running Disposer d’un statut clair et fiable dans Centreon (OK / CRITICAL si le conteneur n’est pas démarré) Éviter de maintenir un script custom si une solution packagée existe Nous n’avons pas trouvé de plugin officiel Centreon Plugin Pack dédié à OpenVZ pour cette vérification spécifique.Existe-t-il : Un plugin officiel Centreon compatible OpenVZ ? Une bonne pratique recommandée (via SNMP, agent, API, commande système côté hôte) ? Un mode opératoire vali

Bonjour,J’ai une question par rapport à l’Activité métiers (Business Activity). Récemment, on m’a demandé de créer des activités métiers pour mes serveurs, mes applications hébergées. Cependant, je l’ai créé que depuis la semaine dernière. Cependant, les applications et les serveurs existaient depuis pas mal d’année. Par contre, quand je génère un rapport pour mon activité métier, il n’affiche que les valeurs à partir de la création de l’activité métier pour mes serveurs et mes applications. Est-ce normal? Comment je peux faire pour que ce rapport prend toute l’historique de mes serveurs et de mes applications? Ou ce n’est pas du tout possible?Aussi, j’avais déjà quelques activités métiers en place depuis pas mal d’année. Et j’ai modifié les plages d’horaire de rapport de 24x7 en heures ouvrées de 8h à 20h et aussi supprimer quelques indicateurs non utiles à mes rapports. Est-ce que j’aurai une réécriture de mes historique d’activités métiers dans ce cas là, ou bien c’est comme si je r

Hello,I am experiencing an issue with my Centreon IT‑100 license. The “Add Token” button is no longer available in my Centreon interface and has been replaced by “Choose Subscription”, which prevents me from re‑registering or activating my token.According to the Centreon community, this situation occurs when an IT‑100 license is still linked to a previous server, and an unlink operation must be performed on Centreon’s side. This was explained in discussions where moderators indicated that the problem happens when the token has already been registered or when an offline license remains attached to the platform.It was also mentioned that only the Centreon team can unlink the license in such cases, and users were asked to provide their server fingerprint so that the operation can be performed. [thewatch.c...ntreon.com] [thewatch.c...ntreon.com]Here is the fingerprint of my current server:👉 11b3a090fa1e2d59e34af7a4c2d7b3d3edd52a67a574584972ec8297b5f921d1Could you please unlink my IT‑100 l

Hello,I’m encountering an issue with ACL behavior after service discovery in Centreon.Environment: OS: Red Hat Enterprise Linux 9.6 Centreon version: 25.10.9 (Central + Poller + MySQL 8) SELinux: disabled Context: I have configured user ACLs to restrict actions (menus, features, etc.). For resources, I did not create any specific restriction since all users should see all resources. Therefore, I am using the default “All Resources” ACL. Issue:When new services are discovered via service discovery: Non-admin users cannot see the newly created services. Even after logging out and logging back in, the services are still not visible. The only way to make them visible is to manually click the “Reload ACL” button. Additional observations: The log file /var/log/centreon/centAcl.log is always empty. Running the ACL reload command manually does not solve the issue: sudo -u apache /usr/bin/php -q /usr/share/centreon/cron/centAcl.php This command produces no output and does not make

Hi,In the 24.10.22 release notes we can read:> [API] The API no longer returns "null" when trying to acces the /monitoring/servers endpoint (it will now returns the IP address of the pollers). What’s about the /monitoring/downtimes endpoint? Shouldn’t all the endpoints with the same erratic behaviour be fixed once? 

Hello,I’m facing an issue with a discovery rule in Centreon where the inclusion filter does not seem to work as expected.Context: I created a discovery rule to include only interfaces with names containing StackPort. My inclusion rule is configured as: Macro: $name$ Regexp: ^StackPort* Expected behavior:Only interfaces like StackPort1, StackPort2, etc. should be discovered.Actual behavior:When I run the discovery command manually, I can see interfaces such as:'StackPort2' [speed = 160000][status = up][id = 124][type = propVirtual]However, when I perform a manual scan from the Centreon UI, the inclusion filter does not seem to apply, and other interfaces are still discovered.Command used to list interfaces in CLI :sudo -u centreon-engine /usr/lib/centreon/plugins/centreon_cisco_standard_snmp.pl --plugin='network::cisco::standard::snmp::plugin' --mode=list-interfaces --hostname='10.0.0.8' --snmp-version='2c' --snmp-community='public' --disco-show<?xml version="1.0" encoding

Bonjour,Je souhaite avoir des précisions concernant les services de supervision embarqués dans Centreon Monitoring Agent (CMA), notamment sur leur personnalisation.Environnement OS : Red Hat Enterprise Linux 9.6 Plateforme : Centreon 25.10.9 Architecture : Centreon + Poller + DB sur le même serveur SELinux désactivé ContexteLors du déploiement de CMA sur les serveurs, nous constatons que les sondes embarquées sont bien présentes, mais nous ne trouvons pas de moyen clair pour personnaliser leur configuration.En particulier : l’entrée de registreComputer\HKEY_LOCAL_MACHINE\SOFTWARE\Centreon\CentreonMonitoringAgent ne semble pas indiquer de fichier de configuration permettant de modifier ces sondes ; nous souhaiterions adapter certains comportements des contrôles natifs embarqués.
