BBDO2 Deprecation with Centreon 25.10 ReleaseBBDO2

 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

Important change on 21.10 package repository

As you probably already know, Centreon 21.10 is not a supported version anymore (more information here).As a consequence, the RPM package repository for this version has been archived: it moved from https://packages.centreon.com/rpm-standard/21.10 to https://archives.centreon.com/standard/21.10.If your platform is still running 21.10 and you need to update it, please update your YUM or DNF repository configuration to handle this change.

How to use SNMPv3 monitoring plugins in Centreon Open Source (without license)

Hi everyone,I'm using the open source version of Centreon (no license, no commercial subscription) and I would like to monitor equipment like Cisco switches, HP servers, UPS, PDUs, etc. using SNMPv3.I know that with a commercial license, I could simply use the Monitoring Connector Manager to install packs like network-cisco-standard-snmpv3, but in the open source version, only basic modules are available and the rest require a license.That said, I was able to install centreon-pack-operatingsystems-linux-snmpv3 via APT, and it works perfectly for Linux hosts using SNMPv3. So I assume it's technically possible to use SNMPv3 monitoring for other devices as well, but manually, without licensed packs.I’ve already cloned the official centreon-plugins GitHub repo and I can run checks via CLI successfully. How should I configure them properly in the Centreon web interface (host templates, service templates)?This is part of a large-scale migration from SNMPv2 to SNMPv3 across many existing devi

Confused About Monitoring Connectors, Plugins, GitHub Repo & Licensing

Hey everyone,I’m setting up Centreon and I’ve hit a point where I’m confused about how Monitoring Connectors, plugins, and the GitHub plugin repo all relate — especially when it comes to licensing and offline environments.Here’s my current situation and questions: After a fresh install of Centreon, I could install some Monitoring Connectors (I think these are the default/free ones). But I also see many others greyed out — I assume those require a license? I understand that Monitoring Connectors (or Plugin Packs?) are templates that help configure services, but I’m not sure how they relate to the actual plugin scripts (like those in /usr/lib/centreon/plugins/). I also don’t really get the relationship with the GitHub repo (https://github.com/centreon/centreon-plugins). Can I just clone that repo and use it without a license? if I clone it will i be able to use all plugins and won’t need to install connectors/packs etc? If I do clone the GitHub repo, should I clone it on the Centra

Problem 24.10.7 - Web UI

Hello, I'm asking for your help because I recently installed a new Centreon server in version 24.10.7 on a Debian 12 and I'm constantly getting errors for various things that I encounter only in HTTP and never in SSH, in particular for creating a Host. When I want to create one via Web UI and I click on the “Save” button to register my new host, nothing happens and my centreon WEB interface crashes for a few dozen seconds.Another thing is that when I perform various other actions, I constantly get the following messages: “failed to fetch” “Oops, something went wrong” at the bottom of the page. Any idea where this might be coming from?I'm also attaching the source code inspection with Google CHROME to show you the type of error that keeps appearing.Thanks in advance.

How to add my hosts to new host groups?

Hello,I have around 1000 VMs which I added initially into host groups like prod, preprod, uat etc. The VMs are a mix of windows and linux. Now since I will be using snmp templates and some will use linux_snmp and some will use windows_snmp templates, I want to create 2 new host groups - windows and linux. Now I want to add my hosts into these host groups. What would be the easiest way to do it please? via csv import for example. How to add my already added hosts to these new groups without impacting the existing hosts or host groups. For example, I cannot delete and readd all hosts with updated host groups. I dont have autodiscovery license.

How to manage access by membership in Active Directory Groups?

Currently we have a working LDAP connection to our AD but we import users manually and remove them manually when access should be stopped.This is a certain administration effort, the only advantage is that users can user their AD credentials to authenticate.  Target is to manage user access to Centreon only in AD, e.g.,all members of the AD group Group_A should be member of a certain Centreon contact group, e.g. “Admin” all members of the D group Group_B should be member of a certain Centreon contact group, e.g. “ReadUsers” …When a user has been removed from the corresponding AD group access to Centreon should be removed automatically.Long story short: Centreon access rights should be managed fully in AD without need to manage users in Centreon. Is this possible? Official documentation is not very helpful (https://docs.centreon.com/docs/administration/parameters/ldap/).For me this seems to be the standard how authorization should work. I searched in TheWatch as well but I did not found
