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.

How to export "Services by host group" items?

Dear Community!I have been using Centreon for a while and we have been working on migrating our Centreon infrastructure to a new environment.It is important to note that, we are using a lot of “Services by host group” type of configurations.So while preparing for this migration activity, I tried to export the whole configuration (with checking all type of objects in the Export menu). When I checked the content of the export file, I did not find any services which are configured as “Services by host group”. I’m unable to create an export, which contains also the configuration also for services, which are assigned to host groups. Has anybody experienced the same with Centreon Community edition version 24.10.8 ? Thank You very much in advance for the support!

centreon vmware do NOT upgrade to 24.10.8, it will break you configs

Hello,If you are using Centreon (in Configuration > Connectors > Additional Configurations) to manage your Centreon VMware demon , do NOT upgrade to 24.10.8. The configuration manager is completely broken Lost on all the user/pass previously enteredImpossible to fix the config because of JS errorsUser and Password field unusable because all characters in every fields are replaced by stars (yes, even the users) The result will be non-working configuration for the demon and you will loose all the monitoring of the vcenters. The work around for me was to get the config JSON from a backup, restore it under another name, and modify the /etc/sysconfig/centreon_vmware on every poller to force centreon_vmware use this file. Good luck.

Mise en place d’une architecture Centreon distribuée avec notifications centralisées via un broker intermédiaire

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
