Hello, since the rotation GPG key (i suppose) the rpm-standards packages for centreon are unavailable on artifactory.https://packages.centreon.com/ui/native/rpm-standard/I see that they are possibly still on the rpm-test-standardWe need those packages to be back available as soon as possible. If this intended, please tell me what is the expected operation to access those packages again

Hi all,My version of Centreon is 25.10Any idea why its asking for my username/password when I try and use my copied autologin url:https://192.168.20.29/centreon/home/dashboards/library/3?autologin=1&useralias=autologin&token=cQSPFRHWEe When I use this link it works fine without asking for username/password:https://192.168.20.29/centreon?autologin=1&useralias=autologin&token=cQSPFRHWEebut then if doesn’t take me to my dashboard.Interesting if I use my first link after using this link it works fine.thanks for help.Steve.     

Hi,During my migration from 22.10 to 23.04, I had some issues with host auto discovery.The following error is visible in the gorgone log[autodiscovery] -class- host discovery - cannot get host discovery jobs - request error [code: '404'] [message: 'No route found for "GET https://<centreon>/centreon/api/latest/auto-discovery/scheduling/jobs"']The API seams to be good because I am able to check the current version of the api:curl https://<url>/centreon/api/latest/platform/versions{"web":{"version":"23.04.0","major":"23","minor":"04","fix":"0"},"modules":{"centreon-pp-manager":{"version":"23.04.0","major":"23","minor":"04","fix":"0"},"centreon-license-manager":{"version":"23.04.0","major":"23","minor":"04","fix":"0"},"centreon-autodiscovery-server":{"version":"23.04.0","major":"23","minor":"04","fix":"0"}},"widgets":{"Service Monitoring":{"version":"23.04.0","major":"23","minor":"

Hello,Is there a plugin HP MSA 2000 for a poller under DEBIAN ?https://docs.centreon.com/fr/pp/integrations/plugin-packs/procedures/hardware-storage-hp-msa2000-snmp/Thanks,

Hi,I would like to purchase the IT-Edition to be able to install plugins on my centreon. I recently updated to 25.10.I find the web page about licences a bit confusing. It says the free version can be used with up to 100 hosts, and the “IT Edition” is showed as “2.2€/host, 275€ for 125 hosts”.I already use centreon with the Free edition marked as “Up to 100 Hosts” but I already have  300+ hosts that are monitored. Is the “Up to 100 Hosts” limit based on the number of SUPERVIZED hosts or on the number of Centreon poolers? Does that mean that if I only want one Centreon machine (1 pooler) but with 300 supervized machines I can have a licence for 2.2€ per month? Thanks,

Hello, since a migration from the 24.10 platform to the 25.10 on a RHEL9 server (central server with the embed poller), after migration, most macros that were defined on the host don’t seem to be decrypted correctly by the poller.I’m seeing many logs like  fail to decrypt content of macro _HOSTCUSTOM_MACRO: Decryption finalization failed: error:1C800064:Provider routines::bad decryptI have followed correctly the upgrade steps from the documentation and especially for the poller to extract the symetric key at Upgrade from Centreon 24.10 | Centreon Documentation Does anyone face that issue yet ?

Hello,Since upgrade to 25.10, we are facing a weird issue on Host adress form.While in 23.04 this field was most likely “open to any format”, it now requires a “valid IP / FQDN Format”, which is a problem actually for multiple reasons. We can’t modify an existing item that is actually configured with a wrong HOSTADDRESS format, resulting to the following error : We also can’t delete an item that is with this kind of HOSTADDRESS format. It does nothing when we click on delete → Just actualizing the interface, but the host still here, and poller config doesn’t see any change. Even if we restart the poller config, it doesn’t do anything (in case it was a ghost change) We have many commands that uses the HOSTADDRESS value, which is not a valid IP (or FQDN) (for certain a

Hi, I want to check the alerts already defined in prometheus without to use the query mode. Because it is easier for us to define the treshold. Is there a way to ask the result of the alert defined in prometheus withtout ? I have try with the plugins but it doesn’t work.For exemple, If i use the name AlertmanagerFailedReload for this alert :   

Hello,I updated multiple servers to Debian 12 and all Centreon 24.10.18.

Bonjour à toutes et tous,J’ai installé dernièrement un serveur avec Centreon pour superviser des serveur Windows (Windows Serveur 2019 DataCenter build 1809)La supervision avec le CMA en mode sans SSL fonctionne parfaitement,J’ai voulu passer en SSL et la plus de communication entre mes hôtes et le collecteur.J’ai fait le test avec un certificat autosigné et avec un certificat provenant de notre autorité de certification interne.J’ai sans doute loupé une étape. Merci de votre aide.

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 everyone,I’m looking for the most efficient way to generate a list of active services (excluding templates) that do not have any contactgroup defined—neither directly nor inherited from templates.I’d like to explore different methods to achieve this, such as:SQL queries (directly querying the Centreon database) REST API (if applicable) Parsing configuration files (e.g., .conf files in /var/lib/centreon-engine/central/config/)If you’ve already tackled this issue or have any insights, I’d appreciate your input! Which method do you recommend for accuracy and simplicity?Thanks in advance for your help!

Hi, I’ve used an older version Centreon 2.4.1 (yeah really old! lol) and I never had this issue, but now on 25.10 I have the issue where when I delete a host it then deletes all the services linked to the host even the ones that are used by other hosts.  Obviously this is massive issue and will lead to my staff accidentality deleting services when they delete the hosts.  I don’t remember this being an issue in the older versions of Centreon.Is there a workaround for this?  I don’t really want to use service groups / host groups as I don’t want hundreds of different host groups based on my services, I need it to be a bit more flexible.Is there a way to prevents the deletion of the hosts and only allows disabling? or a way to stop centreon deleting the services when the hosts are deleted.thanks in advance.steve.
