Hello,I’m currently facing an issue with our Centreon monitoring and would like to get some advice from the community.We are monitoring several customer virtual machines (mostly Windows) with Centreon, using standard checks such as: ICMP (ping) SNMP (CPU, memory, etc.) Some service checks Recently, one of our VMs crashed with a Windows BSOD. However, no alert was triggered in Centreon: The host was still responding to ping SNMP checks were still returning values Services appeared as OK So from Centreon’s perspective, everything looked healthy, while the OS was actually not operational.We would like to improve our monitoring to detect this kind of situation (OS freeze, BSOD, or unresponsive system), not just network availability.My questions are: What would be the best way to detect that a Windows OS is really alive and responsive? Would using NSClient++ or Centreon Monitoring Agent be the recommended approach in this case? Are there specific checks (uptime, heartbeat, proce

Bonjour,Depuis que j’ai migré vers la version 25.10.5, je suis obligé de redémarrer mon collecteur tous les jours.Le matin je me connecte et le collecteur semble tourner mais nb de machines : 0 et sur la ligne je retrouve la date de la dernière mise à jour de mon collecteur sur fond Orange.Je redémarre mon collecteur et tout se remet à jour naturellement...Comment puis-je outrepasser cette opération qui n’était pas nécessaire sur la version précédente. Il doit y avoir un paramètre qui bloque l’uptime du collecteur.Merci pour vos retoursBonne journée 

Hello, I just updated to 25.10 and when editing a host using Centreon-Web, New host macro value are not saved.I can see the correct form payload values, HTTP status is 200, nothing is shown in centreon-web or sql-errors, but no new entry is added to on_demand_macro_host SQL table. Any idea ? Edit: I just figured out something: the hosts where it’s failing have a large number of macros, hosts with less entries work Thanks

Bonjour,Je cherche à ouvrir des tickets dans mon ITSM (EasyVista) via OpenTicket, mais je rencontre une difficulté avec les macros.Je souhaite passer en paramètre le Catalogue GUID stocké dans la macro EVSM_CATALOG_ID située dans les modèles (templates) de mes services. Lorsque je renseigne le GUID directement dans la règle de notification (champ Catalog GUID), cela fonctionne. En revanche, si j'utilise la variable {$service.custom_variables.EVSM_CATALOG_ID}, la transmission échoue. De plus, je souhaiterais récupérer la valeur présente dans l'alias du service pour l'intégrer dans le champ CI, afin de lier automatiquement le ticket à ce CI.Pourriez-vous m'aider à résoudre ces deux points ?Merci d'avance.English Version  Hello,I am trying to open tickets in my ITSM (EasyVista) using OpenTicket, but I am having an issue with macro integration.I need to pass the Catalog GUID as a parameter.

Bonjour,suite à la mise à jour de centreon (passage à la version 25.10), la licence IT semble ne plus fonctionner.Dans Administration\Extensions\Gestionnaire, elle est bien active (Date de fin de licence : 31/12/9999).

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.

I've been asked to produce a report on the average memory use of our servers.I can get the information I need via a Performance Graph (see below) but, because I've beenasked to do this for several hundred servers, I'm looking for a way to automatethis as much as possible.Is it possible to get average memory use via clapi or SQL queries? Memory use on one server

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.
