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a supported version anymore (more information here).As a consequence, the RPM package repository for this version has been archived: it moved from https://packages.centreon.com/rpm-standard/21.10 to https://archives.centreon.com/standard/21.10.If your platform is still running 21.10 and you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.

Vulnerabilities in Curl CVE-2023-38545 CVE-2023-38546

As you might have heard, 2 vulnerabilities were disclosed on Curl last week.These issues have been undisclosed as CVE-2023-38545 and CVE-2023-38546.These vulnerabilities might have impacts on specific use cases, with specific misconfiguration.Default installation and default use cases should not be impacted.However, we recommend that you update your local package (on pollers and centrals) up to versions 7.69.x or 8.4, depending on your installation.

Best strategy to deploy standard commands and templates to a centreon

I have multiple Centreon instances and wanted to provide a standard configuration to my instances.Currently i am making use of the CLAPI v1 and was considering using the API REST as it seem to be the target now, but as what i want to deploy is provided as a rolling release, i’m wondering if there is a better way to provide commands and templates in a standard way in “readonly” mode and to update them as i roll updates.I wish to deploy that as i deploy configuration files through rpm packages, my hope is that there is some kind of config.d folder that i could make use of to deploy my files so they are added to the available commands and services. Anyone making this kind of updates ?

CPU/ Load charge/ Disk by using SSH

Hi there!I am currently downloading Centreon's open-source version 24.10.I'm struggling and I don't know why.I followed the Centreon documentation: https://docs.centreon.com/fr/pp/integrations/plugin-packs/procedures/operatingsystems-linux-ssh/The problem is that I can’t find the service "OS-Linux-Cpu-SSH-custom" in my Centreon interface.My plugins are updated, so do I need to create this service manually?I created a check command that I use in the host setup, which is:--plugin=os::linux::local::plugin --mode=cpu --hostname=$HOSTADDRESS$ --ssh-option='-l <user>' --warning=70 --critical=90When i restart my poller, no error is return.Can someone help me or redirect me to a blog or tutorial that I can follow?Sorry if I'm not very clear — I'm trying to understand how SSH-Remote monitoring works in Centreon.

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

US repo for installation

Hello folks! I’m trying to do a trial of Centreon; however, our FW policy doesn’t allow for non-US based repos.Googling doesn’t come up with much around the topic, but does anyone know of a US mirror that can be specified rather than using the default that is in amazaon EU-West via jfrogs?

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.

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

License issue

Hello, since migrating the platform from CentOS 7 to Debian 12 following the procedure, I'm experiencing a license issue. The IT-100 license appears to be properly validated, but it still shows 'license required'.The number of hosts has not been exceeded (verified via query). I’ve tried linking and unlinking the license, deleted the epp.license file, uninstalled and reinstalled the Auto Discovery, IT Edition Extensions, and License Manager modules. Nothing has worked so far.The license is used only on this platform, but I suspect the system fingerprint may have changed, even though the IP address remains the same. What else can I do, please?
