Infra Monitoring Platform

Hi folks,Here my feedback/issue after go to 25.10Forced check doesn’t work anymore, success message after push it, but nothing happens When I create a new service, host, or modify anything, I have to restart all centreon stack : systemctl restart centengine to show up the new elements. Export config, restart engine from web is no longer enough Custom macros don’t work on service apply to hostgroup. (ok with linked on multiple hosts or host only)I migrate to a new platform (22.10 to 25.10) by following documentation ‘Migrate from an EL-type OS to another EL-type OS’ 

Hello, I am trying to set up Centreon 24.04 on Debian 12. When I access the Centreon GUI, I encounter a loading issue. Checking the Apache2 logs reveals the following error: [proxy_fcgi:error] [pid 29198] [client 192.168.1.33:61829] AH01071: Got error 'PHP message: PHP Fatal error: Uncaught RuntimeException: Unable to create the "cache" directory (/var/cache/centreon/symfony). in /usr/share/centreon/vendor/symfony/http-kernel/Kernel.php:598 Stack trace: #0 /usr/share/centreon/vendor/symfony/http-kernel/Kernel.php(505): Symfony\Component\HttpKernel\Kernel->buildContainer() #1 /usr/share/centreon/vendor/symfony/http-kernel/Kernel.php(763): Symfony\Component\HttpKernel\Kernel->initializeContainer() #2 /usr/share/centreon/vendor/symfony/http-kernel/Kernel.php(185): Symfony\Component\HttpKernel\Kernel->preBoot() #3 /usr/share/centreon/api/index.php(47): Symfony\Component\HttpKernel\Kernel->handle() #4 {main} thrown in /usr/share/centreon/

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.

 I have installed the it-100 license, when I try to update a plugin or install a new one I get this error 

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!

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 the upgrade from 23.04 to 25.10, we cannot filter the performance graph list.When we type the beginning of a research (e.g ping) → looks like it does a filter and then shows all our existing probes.Are we the only one with this issue ?Best Regards,

Hello Centreon Community/Support,I am experiencing an issue with a custom Lua stream connector script that is designed to send monitoring events to an external system (BEM). The script functions correctly on one Centreon Poller/Central server, but on a different host (which I'll refer to as "Problem Host"), events are consistently being dropped at the filter stage, resulting in the debug log message filter' returned false.I have confirmed that the target system is listening on the expected port (2540) and that the "Problem Host" can establish a TCP connection to it.Problem Description:On a specific Centreon host (the "Problem Host"), the Centreon Broker Lua stream connector is not processing events as expected. The debug logs show that the filter function in the Lua script is rejecting all incoming service status and host status events, even though the same script works perf

Hello everyone,We are monitoring a Vcenter v8 cluster, and all was fine with Centreon 22 (so using the sdk file).Since upgrade to Centreon 25.10, connector is not working anymore. I saw that now there is a JSON file instead of the PM one (file is deprecated).I used the configurator to add my Vcenter, and I can see the JSON file filled with the informations (server ip address and login/pwd stored in crypted mode). As I understand, Centreon 25 is now storing credentials in crypted mode.Issue I’m facing is:I believe that the Vcenter platform is receiving the user credentials in crypted mode so I got a “user failed connection”. I looked in the vcenter log files for this. so the Vcenter is not able to authenticate as user is crypted and unknown for him. Is there a way to fix this ? I know that the restAPI plugin is designed for Vcenter8, but could we monitor all the same functionalities as the vmware_centreon plugin ? 

Hello, I upgraded to version 25.10 and now the centreon_linux_snmp.pl plugin only works for certain checks, such as load mode and swap mode. However, it no longer works with CPU, storage, RAM and memory modes, even though nothing has changed.Furthermore, when I run the command on my poller in CLI, it works, but when I run it from the web interface, I get an ‘execute command failed’ error, even though I have the correct permissions, etc. I really don't understand.Need help, please. 

Hello,I’ve got two VMs to monitor with Centreon. For the first one, I'm using a plugin from Centreon’s GitHub repo centreon-plugins/src/centreon_plugins.pl at develop · centreon/centreon-plugins (github.com)  plugin-path: src/centreon_plugins.pl  For the second VM, I would like to use an RPM instead of pulling the plugin from GitHub.Do you know how I can find the equivalent RPM? Any keywords I should be searching for? Have you used RPMs instead of the GitHub plugins before? Thanks for the help!

With the new, extremely short lifecycle for STS versions (odd-numbered years), have those with only 18 months of support become beta tester versions ?I find this lifecycle choice very surprising.Why does support for STS versions end before the following LTS version is stable and completes its Phase 1 ?Today, if I want to stay on a stable version, I must stay on 24.10 until October 2027, and only then can I double-jump from 24.10 to 26.10, even though 25.10 will no longer be supported.If I upgrade to version 25.10, I'll be forced to upgrade to 26.10, even though it won't be stable yet.I get the impression that these STS versions, like 25.10, offer neither new content nor stability in the short, medium, or long term.I preferred the old cycle.Or at least, in my opinion, it would be better to extend the STS to 24 months.Am I wrong? Have I misunderstood the improvements in this new cycle ? Thanks

SSL certificate problem: unable to get local issuer certificate for "https://x.x.x.x/centreon/api/latest/configuration/hosts/templates".As soon as I want to add a host or create a template, I now get errors like this.Nothing in my configuration has changed except that I upgraded to version 25.10; I was previously on ‘(24.10.)

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,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

We are using a SSO solution to centralize our user authentication flows and because of that users have many many groups.When trying to login through Centreon, those groups data are added within the authentication token, making it reach huge sizes (around 4k characters for now), but the structure of the database on the table “security_authentication_tokens” for the “token” field is limited to 255 characters. i got explained that it is possible within an openid request to ask for a filter on the groups to maybe reduce that token size.Is there something to do in that sense and how can we do it ? This is blocking the deployment of this auth solution at scale. 

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
