Removing the ability to create services linked to multiple hosts or host groupsFeature Sunset

Dear users, In order to simplify and improve the user experience of our software, we plan to remove two features in an upcoming major update:Creating services linked to multiple hosts. Creating services by host group.We understand that these features may still be used by some of you, but we believe they can be replaced by the use of templates. We are making this decision to optimize the software and make it more intuitive. Proposal of solutions when updating the Centreon platform Services linked to multiple hostsCreating a service linked to multiple hosts allows you to have an identical configuration of this service for multiple hosts.This service can be transformed into a service template. A single service will be created for each linked host and will inherit the template you previously created.This update will be performed automatically during the Centreon platform update process (target: Centreon 25.10). Services by Host GroupCreating a service by host group allows for the same serv

BBDO2 Deprecation with Centreon 25.10 ReleaseFeature Sunset

 We wish to inform all users that BBDO2 will be officially deprecated with the 25.10 release of Centreon. This change is part of our ongoing effort to enhance the platform’s performance, security, and compatibility with modern infrastructure requirements. What is BBDO? BBDO, for Binary Broker for Data Operations, is a core protocol for exchanging monitoring data between a Centreon central server and pollers/remote servers.  Why is BBDO2 Being Deprecated? With Broker 22.04.0, we have introduced a new version of BBDO based on Google Protobuf 3.The new protocol remains compatible with the previous one, but introduces new events.There are several key reasons for the depreciation of BBDO2:Performance improvements Flexibility: easier maintenance and enhancements To enable Broker-managed configuration & differential configuration export, which are using Protobuf messages (reduced network footprint for configuration updates).What This Means for You For most of our customers, BBDO3 is aread

BUG 24.10: Inherited command macros always overwritten on new host/host template

Github issue: https://github.com/centreon/centreon/issues/8042 Since 24.10.8 (could also have been introduced in earlier versions) all inherited command macros are directly written on the host with an empty value when a new host is added (only on add, does not happen on update host).This also happens on new Host Templates.Problematic situations that can happen due to this bug:Imagine creating a new host based on template T1, somewhere in the template tree is a command which declares macro $_HOSTOPTIONS$. At the moment the template T1 has no value for the macro defined. The new host gets created and the macro is wrongly written on the host with an empty value. Now I set a macro value for $_HOSTOPTIONS$ on the template T1. The recently created host will never inherit the value from the template due to the directly written empty value on the host itself.So basically the main problem here is, that the macro value inheritance gets impaired.Screenshots for better understanding:Before ADD (no

What user for CLAPI command

I’m facing regular issues with using the CLAPI centreon command.Especially in terms of permissions. I face issues regarding permissions on log files or php files, sometimes it’s files created that are blocking gorgone. I was wondering if there was a clear recommendation in terms of what is required in terms of permissions for the execution of a CLAPI centreon command.Is itas root as apache (i’m running in RHEL 9) as centreon (or other centreon linked user like centreon-engine) as a custom user but with centreon as a secondary group  Would someone that faced similar issues please guide me ?Thank you so much

Notification by email not working

Hello,I’m in the process to upgrade/mirgrate from 21.04 to 24.10.Everything is “almost” working, I’m actually working on the mail notification.So I follow the doc here : https://docs.centreon.com/docs/administration/postfix/Everything is working as expected, I can sent mail using the test commandecho "Test" | mail -s "Test" user@isp.comBut on Centreon, I do not receive any notification.The Centreon server didn’t even try to sent something (no logs on my SMTP server).So something seems misconfigured on the server, I have doubt on the postfix service itself, as the status is active (exited) but on the doc it is active (running). Also, I have doubt on the command as maybe something changed during the 21.04 → 24.10 upgrade that didn’t update correctly. Error seems the same as Thanks a lot !

Bad Macro name with API v1 and get macro on service

Hello,We’ve encountered a recurring issue when querying service macros via the Rest API (v1) (getmacro action). Some macro names are returned truncated or corrupted, it’s random.I can recreate macro, and it’s working but not for longtime.For example, instead of returning:{ "macro name": "TICKET_ID", "macro value": "12345678" } We sometimes receive:   {      "macro name": "ITICAL",      "macro value": "350",      "is_password": "",      "description": "OPTIONNEL - Seuil mémoire en MB",      "source": "App-SS-Process-Memory\nTI"    },    {      "macro name": "KET_ID",      "macro value": "",      "is_password": "",      "description": "",      "source": "generic-active-service-custom\nSE"    }, I have many MACRO on sercice, and i have this problem on differents servicses.  The call is :{ "action": "getmacro", "object": "service", "values": "HOSTNAME;SERVICENAME"}

Error with cbd 24.10 (input/output deleted from broker configuration)

Hello,I have been experiencing several problems since today with version 24.10 Centreon On-Prem.My pollers can no longer communicate with my central server on port 5669.I have tried the various Centreon procedures to resolve this (restarting the centengine and gorgoned services, looking at the logs, etc.).I'm quite used to these problems in general but this time, strange behaviour is occurring.It seems that the input and output configuration of my central-module-master and central-broker-master have disappeared from the files when I display them via the CLI in SSH.I tried to see what was happening via the GUI but when I recreated and saved them, an error appeared: Could not resolve host: centreon.mysite.com for ‘https://centreon.mysite.com/centreon/api/latest/configuration/broker/1/outputs’.(Obviously, I've replaced the url in the error to show you)Same thing when I modify the input : Could not resolve host: centreon.mysite.com for ‘https://centreon.mysite.com/centreon/api/latest/confi

Alma Linux 10.8 Update Breaking Centreon

Being the first of the month is was time for me to run my regular updates for my Centreon VMs.  This is  running AlmaLinux 8.10 Kernel 4.18.0-553.60.1.e18_10.x86_64 and Centreon Version 24.04.15 after the new update and it has broken all of my monitoring.  Execute command failed is the error that I am seeing in the status page.  I have rebooted the machine with no change.  Some googling came up with making sure SELinux was disabled.  Initially it was not, but I did change that, rebooted the system again and still getting the same error.Fortunately this is a VM and I did take a snapshot prior to updating so was able to restore functionality quickly.  Did some more research, ran the update again, but still the same result.  Anyone else run into the same issue?  Or would have any further thoughts on what I should check?
