Hello,Most of the Centreon web menu pages appear blank since the update. I've cleared my browser cache, tested in incognito mode, and cleared the Symfony cache. Nothing works.I checked the logs in /var/log/apache2/error.log and found this, but it might be unrelated:[Thu May 14 12:46:32.281519 2026] [proxy_fcgi:error] [pid 774:tid 774] [client 82.66.247.24:65357] AH01071: Got error 'PHP message: PHP Warning:  Undefined variable $sessionKeyFreeze in /usr/share/centreon/www/include/Administration/parameters/general/form.php on line 279; PHP message: PHP Warning:  touch(): Utime failed: Syst\xc3\xa8me de fichiers accessible en lecture seulement in /usr/share/centreon/vendor/smarty/smarty/libs/sysplugins/smarty_template_compiled.php on line 178; PHP message: PHP Warning:  touch(): Utime failed: Syst\xc3\xa8me de fichiers accessible en lecture seulement in /usr/share/centreon/vendor/smarty/smarty/libs/sysplugins/smarty_template_compiled.php on line 188', referer:

Hello,After upgrading Centreon on AlmaLinux 9 from version 24.10.23 to 24.10.24, I am no longer able to modify any host, for example rename it.When I try to save the modification, I get the following error message: Unexpected return statusI am able to clone the host, but modifying an existing host is not possible.In /var/log/centreon/centreon-web.log, I can see the following error:[2026-05-05T14:23:47+02:00] ERROR : Error during host/hostTemplate update | {"custom":{"hostId":332,"isTemplate":false,"exception":{"message":"Unexpected return status","trace":"#0 /usr/share/centreon/www/include/configuration/configObject/host/DB-Func.php(2912): callHostApi()\n#1 /usr/share/centreon/www/include/configuration/configObject/host/DB-Func.php(2820): updateByApi()\n#2

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 recently upgraded a Centreon platform from 24.04 to 24.10 on AlmaLinux 9.The upgrade initially failed because of PHP dependency conflicts (PHP 8.1 vs PHP 8.2 modular filtering), but the platform is now running correctly with:PHP 8.2.30centreon-web 24.10.24API responding correctlyGorgone runningPollers and monitoring workingHowever, I still have an issue with host templates.When editing  templates in the UI, I get:"Host template not found"In the logs, I see API calls like:PATCH /centreon/api/latest/configuration/hosts/templates/<id> 2026-05-06T14:39:52+0200] [ERROR] Host template not found {"custom":{"host_template_id":737},"exception":null,"default":{"request_infos":{"uri":"/centreon/api/latest/configuration/hosts/templates/737","http_method":"PATCH","server":"127.0.0.1"}}} [2026-05-06T14:39:52+0200] [DEBUG] Data not found.

Bonjour,Nous avons plusieurs tâches de découvertes d’hôtes .Existe-t-il un plugin permettant de remonter une alerte dans le cas d’erreur ou de dysfonctionnement d’une tache de découverte?Aujourd’hui le seul moyen , que je connaisse, pour vérifier l’état des taches est d’aller manuellement regarder dans le menu  Configuration > Hôtes > Découverte.Cdt

Hello everyone, I'm having an issue—apparently a communication problem—between my two collectors and my central server. After investigating and conducting extensive research, particularly in the logs, I'm seeing errors when reading the socket data coming from the poller's IP. Here's an excerpt:Central:central-broker-master.logPoller 1:centengine.log For your information, the operating systems are AlmaLinux 8 for the central server and AlmaLinux 9 for the pollers. I installed the latest updates on 25.10.25 Could you help me resolve this issue and let me know if there are any similar cases curr

Bonjour j’aimerai passer à la version 25.10. SI jamais celle ci me pose des problèmes est ce que le downgrade de version est-il possible ou faut-il privilégier de restaurer une backup de la 24.10 ?

Hi all,I’m figureing out how to monitor Centreon MAP with the Centreon MAP pack.An api username/password is asked but where can I found these elements ?jfr

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-bdaf280f86b038d7ec34c7862026-04-2

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 gorg

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]
