Erreur d'affichage du theme apres Upgrade vers 24.10

Bonjour a tous, Je viens tout juste de mettre à jour mon Centreon de la version 22.04 à 24.10, et l’opération s’est bien déroulée. Les versions du central et des pollers sont à jour, tout comme le serveur de base de données, qui utilise désormais MariaDB 10.11.Cependant, je rencontre un souci d’affichage global de l’interface web. Il semble que Centreon n’arrive pas à charger correctement le thème, même après avoir vidé le cache de mon navigateur.Test fait en ingconito, meme resulta.Auriez-vous une piste ou une solution à me proposer, s’il vous plaît ?A savoir que je suis sur AlmaLinux 8.Merci d’avance pour votre aide.;)

Unsecure install of Centreon Monitoring Agent

Hello, I would like to test Centreon Monitoring Agent on my LAB Centreon, freshly updated on 24.10.7. I followed the installation manual here : https://docs.centreon.com/fr/pp/integrations/plugin-packs/getting-started/how-to-guides/cma/I understood that the connection between the poller and CMA agent must be secure on production. This means it may not be required in a demo/test environment. However, I can't find any further information on this.Also, the "Public certificate file name" and "Private key file name" fields in the Poller/agent configuration section seem to be mandatory. Does this mean that the poller-agent connection must be secure regardless of the environment?Thanks!

Use API - There was an consistency error in the exported files

Hi, I have a problem using the APIs.I created my API with the admin accountcurl -s -d "username=admin&password=MyPassword" -H "Content-Type: application/x-www-form-urlencoded" -X POST https://Website/centreon/api/index.php?action=authenticate{"authToken": "MyAPI"} curl -s -H ‘X-AUTH-TOKEN:'MyAPI’' -H “Content-Type: application/json” -X GET 'https://Website/centreon/api/latest/configuration/monitoring-servers/7/generate-and-reload' It returns the error {"code":500, "message": "There was an inconsistency error in the exported files - please use the legacy export menu to troubleshoot"}I'm using Centreon version 24.10.7.   There's an IP to access the web interface in front of a reverse proxy for the central unit. Another IP is assigned to the central unit for communication with pollers.I don't understand where my problem comes from.

Problem plugin vmware

Hi I have had a problem with centreon updates for some time. My version is 24.10.8. The problem is in the vmware infrastructure monitoring plugin. Previously (based on the centreon_vmware.pm file) everything worked fine. After updates (from several versions within 24.10) the centreon_vmware service does not want to start. When I change the option to old in the /etc/default/centreon_vmware file and restore the centreon_vmware.pm file, everything returns to normal.Here is the configuration and logs after updates (the last one to 24.10.8), which do not work well.My instance: Centreon 24.10.8, Debian 12. $ ls -lrazem 44-rw-rw---- 1 www-data www-data 1287 2018-10-17 centreon.conf.php-rw-r----- 1 centreon centreon 390 06-24 08:25 centreontrapd.pm-rw-rw-r-- 1 centreon centreon 390 2024-05-16 centreontrapd.pm.dpkg-dist-rw-rw---- 1 centreon-gorgone centreon 626 06-24 08:24 centreon_vmware.json-rw-r--r-- 1 centreon centreon 812 03-28 09:37 centreon_vmware.pm

"Loading monitoring connectors" page loading is very slow

Hello,I’m using the Debian Bookworm Centreon image you provide. The loading of the “Loading monitoring connectors” is very very slow, but more generally browsing in any page is quite slow I tuned few Mariadb SQL Backend settings and also tuned some PHP settings but it’s still very slow What is strange is that the CPU usage and memory usage is not full (around 50%) Any idea would be very appreciated Many thanks

Migrating Centreon 21.04 to 24.04 on another VM

Hello everyone, I would like to upgrade my Centreon 21.04 to 24.04.To do so, I installed Centreon 24.04 on a new Debian VM and imported my database. The problem is that I get these error messages when I click on pollers which, I think, are the ones that make it not work : Database incident 1Collectors out of order 1 My database is in MariaDB, I've activated gorgone from the user list, I've deleted autodiscovery in extensions because I'm asked for a license (which I don't have). Could you please help me? Thanks in advance.

SSO et API Rest

Je teste actuellement une intégration avec Centreon via l’API REST (en utilisant les endpoints natifs de Centreon).Je voudrais savoir s’il est possible d’utiliser cette API tout en bénéficiant du SSO (LDAP) déjà en place.Je n’ai pas accès à une plateforme de test avec le SSO activé, mais chez l’utilisateur final, l’authentification SSO via LDAP fonctionne sur l’interface web de Centreon.Ma question est donc la suivante :Est-il possible d’utiliser le SSO (basé sur LDAP) pour récupérer le token nécessaire aux appels API ?Et si oui, y a-t-il une documentation précisant les en-têtes ou paramètres spécifiques à fournir (par exemple en complément du UseDefaultCredentials = true dans le handler) ?Merci d’avance pour vos retours !

I'm monitoring a Windows client using Centreon Monitoring Agent (CMA) with TLS certificates. The agent has loaded the certificates successfully, and the Linux-based poller connects via port 4317.I believe the certificate setup is correct (client cert, key, and CA), but host and service checks are failing with errors like:Error: Host check command execution failed: could not create process 'cmd.exe': No such file or directory Error: Service check command execution failed: could not create process '{check:memory,': No such file or directory Error: Service check command execution failed: could not create process '{check:cpu_percentage,': No such file or directory Error: Service check command execution failed: could not create process 'C:Program FilesCentreonPlugins/centreon_plugins.exe': No such file or directory Error: Service check command execution failed: could not create process '{check:health,': No such file or directory Error: Service check command execution failed: could not creat

Deletion of expired tokens and log files

Hi,Deletion of the expired tokens is logging this : 1) Does it really need to be executed every minutes? As you can see in the log I changed the crontab entry to do this only every five minutes (as a test, I did not observed issue). Every five minutes still seems uselessly too frequent. Do you think it can be done less frequently? Like every hour or so? What’s those tokens’s validity period? 2) What are “tokens which are not linked to a refresh tokens”? Are they the tokens manually created from the UI, from the “API Tokens” menu? I guess they probably even less need to be purged so much frequently than the refresh tokens do, do they? 3) I see a third  line about “expired sessions”, can you tell what is this purge doing? Also, isn’t every minute a bit excessive?  4) I take the opportunity to say that the fact that an upgrade of the centreon-web package systematically overwrites the /etc/cron.d/centreon (ie: even when it has absolutely  no reason to do so) is an issue. I know that one ma
