Bonjour,J’ai un problème concernant l’ajout des plugins par exemple je souhaite ajouter le plugins Linux CMA ou Windows CMA j’ai cette erreur sur l’interface web : Internal server error from license server.Dans les logs de licence nginx voici l’erreur que j’ai : ERROR : 0|0|[RestInternalServerErrorException] https://api.imp.centreon.com/v2/auth/instance : Internal Server Error | {"custom":null,"exception":null,"default":{"request_infos":{"uri":"/centreon/api/internal.php?object=centreon_pp_manager_pluginpack&action=checkDependency","http_method":"POST","server":"centreon.mydomain.com"}}} J’ai cherché pas mal sur internet mais il n’y aucun topic qui correspond à mon problème J’ai une licence IT-100

Did an upgrade from 24.10 to 25.10.  Rocky 10.  After the upgrade, I seem unable to interact with any of the checks.  I can’t forced re-checks or acknowledge alerts.  Check seem to be running, but ack’ing no longer functions.  What should I look at to debug?  Tailing logs actually doesn’t seem to reveal that much. Thanks 

Hi,I have centreon 24.10.18 when trying to visualise graphs from the web interface I have a “fail to fetch” error on chromium and “network error when attempting to fetch ressource” in firefox. This is for all hosts data I have tried.I tried the following without success:I looked in centreon logs under /var/log/centreon /var/log/centreon-gorgone /var/log/centreon-broker /var/log/centreon-engineI could not find anything that seems related to the error in the web browser but I might have overllooked something as there is a large amount of logs.I restarted centreon services: cbd centengine centreontrapd gorgoned . Then rebooted the server I cleared browser cache I tried with another userAny suggestions on what I should try next? 

Goodmorning,I’ve a router with 2 IP address, example IP 10.0.0.1 LAN and 1.1.1.2 WAN.I add the host with FQDN that reply to LAN IP address 10.0.0.1.I try to duplicate ping service, called ping_1, and in EXTRAOPTIONS I put -H 1.1.1.2 to ping the WAN IP via another internet connection, to monitor if WAN link is working.After exporting the configuration I’ve this result: Performance data10.0.0.1rta=10.750ms;200.000;400.000;0; 10.0.0.1pl=0%;20;50;0;100 10.0.0.1rtmax=11.008ms;;;; 10.0.0.1rtmin=10.607ms;;;; 1.1.1.2rta=1.027ms;200.000;400.000;0; 1.1.1.2pl=0%;20;50;0;100 1.1.1.2rtmax=1.063ms;;;; 1.1.1.2rtmin=1.010ms;;;;Command/usr/lib64/nagios/plugins/check_icmp-H 10.0.0.1-n 5-w 200,20%-c 400,50%-H 10.0.0.11.1.1.2 It’s possible to overwrite the IP address from 10.0.0.1 to 1.1.1.2?If it’s not possible, in this scenario, if WAN link goes down - IP 1.1.1.2 not reachable via ping but LAN IP 10.0.0.1 continue to ping, I receive any alarm form Centreon?Thanks

Hi,In Centreon 24.10.17, I notice a one-hour difference between the maintenance start time displayed in the Status view and the view dedicated to maintenance (Monitoring / Downtimes).Users are confused.  

La fonction d’export CSV est-elle / sera implémentée dans les resources table comme dans la page ressources status ?

DescriptionHello,We are facing a critical issue after upgrading Centreon from 25.10.2 to 25.10.6 on a production platform.Context Centreon license: IT-100 Centreon version: 25.10.6 (upgrade from 25.10.2) Architecture: 1 × Centreon Central – Oracle Linux 9.7 1 × Centreon Poller – Oracle Linux 9.7 Use case: Oracle Database supervision (standard Centreon Oracle plugins) Issue observedSince upgrading to 25.10.6, the supervision is completely broken.All service macros are generated with the prefix raw::, for example: raw::$_SERVICEOUTPUT$ raw::$_HOSTADDRESS$ raw::$_SERVICESTATE$ This raw:: prefix is not interpreted by centreon-engine, which causes: Invalid command lines Plugins failing to execute Services stuck in CRITICAL / UNKNOWN Global supervision failure (including basic checks like Ping) What we verified / tried The issue appeared immediately after the upgrade to 25.10.6 The same configuration was working correctly in 25.10.2 Rollback of centreon-engine on the

Bonjour, J’ai remarqué que la découverte des Datastores étaient faites sur le Vcenter et non sur les ESX.Le problème que je rencontre est que depuis le Vcenter tous les datastores sont visibles or depuis les ESX ce n’est pas le cas. Je me retrouve donc avec des services sur mes ESX essayant de voir des datastores auxquels ils n’ont pas accès. Avez vous une solution qui permettrait de valider que l’ESX voit bien ces datastores avant de les ajouter dans les services ? Merci 

Bonjour,Existe t-il des checks, plugins spécifiques aux serveurs windows rds/tse ?

Bonjour,Je vous explique ma situation pour imager la problématique.Aujourd’hui j’aimerai que lorsqu’un host est down par exemple, qu’il envoie en journée une notification à un client (ActeurA) mais qu’à partir disons de 19h à 7h qu’il envoie au groupe astreinte (ActeurB).La problématique étant qu’aujourd’hui on peux ne pas créer de règles pour faire cela ou du moins pas à ma connaissance.

Hi,Since the NSClient++ project has been on a long break (from april 2018 and november 2023) we have never included its releases in our continuous integration processes. But since then, the project show an impressive level of activity.As we have been very busy doig a lot of other things, we have fallen far behind on this updating the base version of NSClient++ used for our builds.We’re currently trying to bridge this gap and given the wide number of changes, we may expect some regressions.Please feel welcome to use this pre-release and give us feedback here!Here are the known issues (I’ll update them as they’ll be found):The old authentication (using --legacy-password and no login) does not seem to work anymore. Since it’s not a good practice, you’re invited to switch to  --username and --password. NB: the apps::nsclient::restapi::plugin needs this commit to handle this authentication process. 

Hello,Here is the context: I want to have a single dashboard view for each customer.To do this, I created a viewerclientA user with a very restricted viewerclientA ACL that only allows read access to dashboards. In addition, I shared the relevant dashboard with my admin account for the viewerclientA account, so it can access it.However, they cannot see certain widgets on the dashboard. Could you please advise me on the changes that need to be made to the ACL in order to gain access?The error message can be seen in the photo.​​​​​​  

I'm planning to buy a Midea 1 Ton Inverter AC for my bedroom (approx. 100‑120 sq ft) and wanted to get some real user feedback before making the purchase.After browsing around, I noticed some websites are offering good prices on Midea ACs, and their specs look promising. But before I decide, I have a few questions:

Hello, After upgrading from 24.04 to 25.10 we encounter an issue with centreon-engine reload. When the reload is performed the variable/macro $CENTREONPLUGINS$ becomes empty and the checks that depend on it fail. Restarting the service solves the issue. In the centreon-engine logfile I found the following:[2026-02-04T08:44:34.117+01:00] [process] [info] [683729] Reloading...[2026-02-04T08:44:34.117+01:00] [process] [info] [683729] Starting to reload configuration.[2026-02-04T08:44:34.249+01:00] [config] [error] [683729] Cannot apply new configuration: Could not modify a host escalation: host escalation objects can only be added or removed, this is likely a software bug that you should report to Centreon Engine developers[2026-02-04T08:44:34.340+01:00] [config] [error] [683729] Error: Could not modify a service escalation: service escalation objects can only be added or removed, this is likely a software bug that you should report to Centreon Engine developers I checked also the logfile

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,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 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, I am trying to set up Centreon 24.04 on Debian 12. When I access the Centreon GUI, I encounter a loading issue.
