Centreon Infra Monitoring

Bonjour a tous, j’ai un script qui envoie du text via snmp, et coté centréon tout fonctionne bien, sauf lorsque mon trap contient un “accent” du style :”é”.  Lorsque mon trap contient des accent il est ecrit en HEX. Je ne comprend pas pourquoi… auriez vous une idée?  J’ai vérifié coté “locale” ou “export” sur mon centrale qui recoit les traps (un debian) tout est bien en anglais utf8. 

Bonjour, que pensez vous de cette approche ? Le but étant donc que ce soit un poller LAN qui exécute la commande de notiffication et non le poller client ou le remote serveur. Objectif Collecter les données via le Poller CLIENT Transporter les données à travers des relai broker sécurisés Laisser le CENTRAL comme maître de configuration et d’IHM Rediriger les notifications vers le Poller LAN, qui exécute la commande CentreonAlerter Architecture[POLL_CLIENT]     ↓ TCP (Broker) [REMOTE_SERVER]     ↓ TCP (Broker) {INTERNET}    ↓ TCP (Broker) [PROXY_WEB_DMZ]    ↓ TCP (Broker) [POLL_LAN] → Notifications exécutées ici     ↓ TCP (Broker) [CENTRAL] ← Web UI, DB, confGénération automatique des certificats Voici un script Bash complet qui génère automatiquement une autorité de certification (CA), un certificat serveur, un certificat client, et les clés privées associées à l’aide d’OpenSSL. Tous les certificats seront valides pendant 10 ans et utilisables pour Centreon Broker avec TLS mutuel

Hello everyone, Since updating my Centreon to 24.10.07, when I configure a host, its community is now hidden.How can I access it and find out which community it is and change it? Thank you for your answers.

I use centreon every day, and the extension manager has worked very well so far.But when I go to this page now, it appears empty without any info :I've already tried to fix it via other help pages, but to no avail. I've updated php, modified the conf, cleared my browser and centreon cache, but nothing works.I'm on version 23.04.0.Please, if you have even one lead, don't hesitate to share it with me. If you have any questions, please don't hesitate to ask.

Hello,I would like to know the release date of the next release of Centreon, i guess the 2025-04. Thank youBest regardsStefano

I cant install Centreon on my Ubuntu 24.04  

Bonjour,Je rencontre un problème de timeout SNMP sur un switch Cisco, mais uniquement depuis l'interface de Centreon.Ce qui fonctionne :Le Ping depuis Centreon vers le switch est OK. La commande snmpget -v 2c -c MaCommunaute! IP_du_Switch .1.3.6.1.2.1.1.1.0 lancée manuellement depuis le terminal de mon poller réussit parfaitement.Ce qui échoue :Dans l'interface Centreon, après avoir configuré l'hôte avec la même IP et la même communauté, tous les services restent en UNKNOWN: SNMP Table Request: Timeout.Conclusion : La communication SNMP entre le poller et le switch est bonne, mais le moteur de Centreon semble incapable d'effectuer la requête. J'ai déjà vérifié et re-déployé la configuration de l'hôte plusieurs fois sans succès.Ma version de Centreon est la 24.04.14.Avez-vous une idée de ce qui pourrait causer ce dysfonctionnement interne ?Merci."

Hello All,I have an issue with the “port” mode in the plugin: Keysight NVOS Rest API All other mode are ok in RestAPI but this mode doesn’t work, in manual service creation or in discovery. The response is : UNKNOWN: 405 Method Not AllowedVersion of plugin: 24.12.2I didn’t see any newer version Keysight version: Keysight Vision E10S - current version 6.8.0.6  (last API guide = version 6.6.1) I try it with an admin account so, no rights issue… and the account is working properly for other modes. Any ideas? Laurent

Hello Centreon addicts, We were using Centreon 2.8.32 community edition for about 3 years and were very happy with it to manage our infra, so we decided to buy a License for upgrade to the latest version and use the commercial plugins.BUT, migration is really not an easy way, I’ve first tried to follow the migration path on Centreon Web Site (https://docs.centreon.com/fr/docs/migrate/migrate-from-3-4/) but we follow a lot of issues with the database that cannot pass the UPGRADE - 22.04.1 step…Then I tried to use the Export feature on the old one but it stays running for days without evolution, then I decided tu use centreon-clapi -e from command-line, and ther a very enormous file is generated (more than 50GB !!!) but it does not reach the end of the export and fails with that error message: A critical diagnostic event occurred in the memory device. Retry operation. <br/>--Novell NMS trap annotation<br/>Variables:<br/>  1: alertSystem<br/>  2: alertTableIndexOID

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.

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.;) 

Hello,I’m currently experiencing an issue in the Service Discovery module of Centreon.When trying to scan services for a specific host, the search field should suggest the host as I start typing its name (after entering the first 3 letters, for instance). However, in my case, no suggestions appear, even though the host is properly configured in the system and enabled.🔍 Expected behavior:When typing the first letters of a host name (e.g., "Cen"), the host "Centreon-Server" should appear in the suggestion list.🐞 Observed behavior:No suggestion is shown, even though the host exists and is fully configured (status: enabled, correct poller, and template applied).📎 Attached screenshots: Host Configuration (Host “aaaaaa” exists and is enabled)     Service Discovery search box (typing “Centreon” returns nothing)     Could you please advise if this is a known issue or if there are specific requirements for the host to appear in the Service Discovery module?Thanks in advance for your help.

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
