Infra Monitoring Platform

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,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

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 ? 

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

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,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,
