Vulnerability Management: What if Centreon could track your CVEs in real-time?

Hello Watchers!At Centreon, we are constantly exploring new ways to make your IT operations smoother and more insightful. Today, we’re looking into a strategic topic and we’d love to get your thoughts: The convergence of Monitoring and Cybersecurity.Since Centreon already monitors your assets (OS, web servers, databases, networking gear) and often knows their versions, we are considering an integration that crosses this data with real-time CVE (Common Vulnerabilities and Exposures) databases.The vision: A new security bulletin is released, and Centreon immediately flags the 15 servers in your infrastructure that are at risk—without you needing to trigger a manual scan.Before we dive deeper into this feature, we want to hear about your current reality:How do you manage vulnerabilities today? Do you use dedicated tools or is it a more manual process?

VMWare 8 connector : First stone

Hello everyone, As part of our project to update our dedicated VMware connectors, we are deploying the foundation of the VMware 8 ESX monitoring connector via REST API this month. This connector is a lightweight version, as it only includes CPU, memory, power and host discovery modes. We have already planned to enhance this connector in the coming months with new modes. It is marked as experimental because, at this stage, we still need to verify its functionality with numerous metrics (as may be the case in certain production environments). Feel free to share your feedback on this and more generally on this connector here. We will keep you informed of progress on this subject.

About Linux SNMP version 3

Dear Watchers,It had been asked for a while, we released it last December: a SNMP version 3 template is provided for Linux in our Monitoring Connectors. The documentation can be found there.I invite you to tell us here as a reply to this post, if you have feedback to give us about it.Does it fit your needs? Is it easy enough to use? Is the documentation clear?Any feedback will be great!Once we judge that the template is satisfying enough given your feedback, we’ll merge it into the Linux SNMP monitoring connector and apply the same method with

Does MQTT mean something to you? And Mosquitto?

Hello everyone,We started working on MQTT and more specifically Mosquitto with the aim of making a new monitoring connector for it. We already have some ideas but we would like to know if any of you are already using Mosquitto and if so for what purpose do you use it? But also your wishes regarding the monitoring of it.

What Monitoring Connectors need a SNMP version 3 template?

Dear Watchers,As I said here, we experimented a new SNMP version 3 template for Linux.We are planning to add similar SNMP version 3 templates to other monitoring connectors to make it easier to use SNMP v3 (I agree it's not ideal to use the $_SERVICEEXTRAOPTION$ macro for that) in more contexts.What I'm proposing you here is to answer to my post by giving:The name of the monitoring connector or the host template you'd like to see support SNMP v3 macros. The desired security levels (noAuthNoPriv, authNoPriv, authPriv).Then we'll prioritize the posts that will receive the highest number of "thumbs up" to deliver new templates in the monitoring connectors.Can’t wait for your suggestions!PS: If what you want is a template that do not exist yet as a mo

Problem with Range Definition

NSClient++: bridging the gap

Hi,Since the NSClient++ project has been on a long break (from april 2018 and november 2023) we have never included its releases in our continuous integration processes. But since then, the project show an impressive level of activity.As we have been very busy doig a lot of other things, we have fallen far behind on this updating the base version of NSClient++ used for our builds.We’re currently trying to bridge this gap and given the wide number of changes, we may expect some regressions.Please feel welcome to use this pre-release and give us feedback here!Here are the known issues (I’ll update them as they’ll be found):The old authentication (using --legacy-password and no login) doe

Migrations 22.10 vers 25.10 macro de services non interpretées

Bonjour,Je viens de migrer mon centreon 22.10 vers 25.10 centos7 vers Debian12. Tout est parfaitement fonctionnel mis à part les macros des services par groupe d’hôtes qui ne sont plus interprétées et non présentes dans le fichier /etc/centreon-engine/services.cfgEn revanche les macros des services par hôtes et les macros d’hôtes sont elles bien interprétées et présentes dans les fichiers de config.Est ce qu’il y a un changement dans la prise en charge de ses macros ?J’ai essayé de passer par des templates pour mettre les macros mais comme se sont des templates lées à des services de groupes d’hôtes le résultat est le même.

Support for monitoring latest Debian and RedHat host with usual tools

Hello,I think you must separate the client support and server support in the Centreon ecosystem.As we don’t need the support for installing the server part of Centreon early on new distribution releasesWe need it as soon as possible for monitoring hosts. Because that is the goal on a monitoring solution.As today , 3 months after Debian 13 release and 6 month after the RedHat 10 release, we can’t monitor efficiently theses hosts.How can I say to customers that they will not be monitored because Centreon is unable to support majors OS at their release and event months after ?CMA is not ready for production (too young, features are missing, new tcp ports, new security mechanism, changing enterprise way to do are long path.), so we can't deploy it yet.You must ensure a period of transition when changing this type of components, by still providing the previous agents and the new one.

Cisco Meraki Rest API: Important updateNews

Cisco Meraki recently announced a significant change to base Uniform Resource Identifiers (URIs) as part of their continuous security hardening processes, requests to unsupported base URIs will start to fail on November 17, 2025. This means that for the Cisco Meraki Rest API connector, using the default value api.meraki.com for your hostname will work for most of the world. However, for organizations hosted in the following country dashboards, you need to override this value and specify the respective base URI instead: Canada: https://api.meraki.ca/api/v1 China: https://api.meraki.cn/api/v1

The changes only take effect when I restart the Centengine.I found this error in gorgoned.log : [legacycmd] Event: [ack] [] {"data":{"error":"unknown_action","message":"action 'ACTIONENGINE' is unknown"},"code":1}Thank you
