Infra Monitoring Platform

Hello,We’re facing an issue on our side with Centreon.When a host stops responding or is powered off, we receive all alerts for every service in DOWN or UNKNOWN state, which amounts to around thirty emails per host.I would like to ensure that if a server no longer responds to ping, only that alert is sent to the team responsible for that host, and not the 30 other emails related to services that are no longer responding.Is there an easy mechanism to implement so that we no longer receive all service alerts when the host is not responding, and only get the notification that the host is unreachable?I have seen the “parent-child” dependency mechanism, but it has to be configured host by host, and I would like to implement this for several hundred servers.Thank you,Laurent

Hello,Before updating to 25.10.5, OpenTickets was working correctly.Since the update, I now get the following error message: "cannot find provider".  In my rule, the connection test is OK.In the widget, I can also select the rule without any issue.Do you have any idea what could be causing this problem?I already tried to downgrade and re-upgrade the module: UPDATE modules_informations SET mod_release = '25.10.0' WHERE name = 'centreon-open-tickets'; Then I re-updated it using the orange update button, but the issue is still there.

Hello everyone,I tried to update Centreon from version 24.10.12 to 25.10.5 yesterday. The update process worked as expected, but after the update, there were some unexpected issues.I could not delete hosts and services, could not create new templates, and could not edit existing templates. In some cases, Sometimes when saving it would just throw an empty page. I couldn't find any errors in the log files, and the UI did not throw any exceptions either. Cloning services, hosts, and templates works as expected.I was just wondering if this is a known bug that will be fixed in the next minor update or if this is an edge case.For testing, I disabled SELinux and removed any security-related, non-Centreon HTTPD configuration.Thanks in advance!

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 guys, currently trying to install Centreon 25.10 using packages and so far I’m stuck at the web installation part.

Hello everyone,I’m trying to monitor Proxmox VMs using Centreon with the Proxmox VE Rest API plugin. I’ve followed the official documentation as well as the steps described on these pages:Centreon Plugin Packs Documentation : https://docs.centreon.com/pp/integrations/plugin-packs/procedures/virtualization-proxmox-ve-restapi/Proxmox VE Rest API Plugin Procedure : https://docs.centreon.com/docs/monitoring/pluginpacks/#checking-the-monitoring-procedureI’ve configured the plugin with the correct credentials and macros, but I’m facing two issues:When I run the plugin manually or through Centreon, I get the following error:UNKNOWN: 401 authentication failureI also installed the Proxmox VE connector directly from Centreon and configured my host using the provided template. However, when I check the host availability, it shows 100% undetermined.I’m wondering if this could be related to:the realm (pam vs pve),SSL s

Hello i can navigate in my centreon but impossible to create objects like template, host etc. Can you help me please ?

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]  

 Hello, I don't know why, but I can no longer create objects or interact. I'm getting web errors everywhere. Can you help me, please? 

Hello,Since upgrading to Centreon 25.10, I noticed a change in the Configuration interface.When browsing Hosts or Services, I can no longer: See the total number of hosts or services Display more than 100 entries in the list (pagination or total count seems to be missing) In previous versions, it was possible to view the total count and navigate beyond 100 objects.Is this: An intentional UI/UX change in 25.10? A known limitation or bug? Something configurable ?  Thank you.

Bonjour,Je demande à l’aide car je sèche depuis plusieurs jours de recherche 😑J’ai lu la doc DSM, debug la partie SNMP, mais j’en arrive toujours au même, les slots restent en status pending et lors de la réception d’une trap j’ai le message dans les log dsm ERROR - [find_slot_id] cannot find slot [alarm id = 23132##APBUREAU [host id = 200] [pool prefix = AP] La partie trap SNMP est ok, le service passif est bien configuré et relié.

Can you confirm the EOL for the Centreon MAP module ?I think it’ll be replaced by the Dashboard

 When youd edit a host with a snmp community (update) the frontend shows ******* (obfuscated) snmp community.Since 24.10.14 the old php code handles this correct.In the latest minor version the "update host" has changed to be saved via API. The API doesn't handle the ****** for the comunity and saves it to the database.reproduce:create new host on version 24.10.16
