Hello,J’ai un soucis avec mon serveur distant que j’ai rattaché au Central. La supervision marche à la fois en local et la vue depuis le Central mais sur le serveur distant je rencontre sur tous mes services supervisés (plugins tiers stormshield/cisco, etc...) des soucis d’affichage concernant les commandes. Ils m’indiquent en capture: Les plugins j’ai comparé, c’est à la fois pour du service nrpe3 qui necessite pas de mdp et snmpv3. En allant plus loin dans la recherche j’ai trouvé dans ma base de données locale que les groupes d’hôtes et de services sont inexistants. Et c’est un vrai problème car j’ai plus de 30 hôtes supervisés, des groupes d’hôtes pour le filtrage et près de 300 services. J’ai fait des montées de mon Central et serveur distant en 24.04.26 mais le problème persiste. J’ai déjà redémarré les machines, réactualisé les services mais rien à faire.Auriez-vous une idée de comment rectifier cela s’il vous plaît ? 🙏 PS: j’ai déjà réinstallé Centreon sur le serveur distant m

Every month, Centreon extends its monitoring connector catalog and implements new ones, allowing you to connect your IT monitoring with more ITOps tools.The result: increased visibility and business observability capabilities. We also offer enhancements and fixes on existing connectors.Here is the latest news on your best allies: our monitoring connectors!This August update includes a lot of enhancements including, in particular, Stormshield SNMP enhancements and bug fixes, as well as two new connectors : Dynamics AX CMA and Quadstor CMA . More details on this month’s monitoring connectors can be found in the release note. Also, heads up 🎉: we're preparing the beta launch of our brand new Rust-based SNMP collection for September, we believe you will love it. Rust plugins are significantly faster and lighter on resources than their Perl equivalents, which matters most if you're polling large device fleets or high volumes of OIDs. We're looking to build a list of motivated beta testers

Hi,I have for a couple months now had issues mainly with the hosts and ICMP. Hosts are pinged every minute to get the UP/DOWN status. I’ve noticed that every other ping is basically failing in a “CRITICAL”. I have tried manually to ping some of these hosts from the same server and there are no network related issues.The issues seem to mainly be related to performance. For services UP/DOWN these checks work better but they are scanned every 5 minutes.Occassionally there can be a PROCESS TIMEOUT. I’m running centreon 24.10.25 on Debian 12 with 4 vCPU and 16 GB memory.We have 478 hosts in our centreon environment and 2052 services. This is running on one cenral poller.I’m thinking about setting up one more poller to see if it might solve things.The “tuning” tab on the engine configuration looks like this. Engine statistics:

Hello,Centreon version : 24.10.29I only have a single, standalone central server, nothing else. Actions on the web interface are not being applied like acknowledging an altert, planning downtime or forcing a check control. I noticed that exporting the configuration does not trigger write in gorgoned.log nor centengine.logI also noticed that gorgone service is running fine, but is not listening on port 8085 for API calls from the web interface. IS this normal behavior ?Also, centreon-web.log last write timestamp is 22 July (2 weeks ago) which means the actions I am launching from the web UI are not being detected somehow. I checked write permissions in centreon directories. They seem fine :/etc/centreon # ls -l /etc/centreon-engine/total 304-rw-rw-r-- 1 www-data centreon-engine 4005 24 juil. 18:18 centengine.cfg-rw-rw-r-- 1 www-data centreon-engine 17509 24 juil. 18:18 commands.cfgdrwxrwxr-x 2 www-data centreon-engine 4096 6 nov. 2024 conf.d-rw-rw-r-- 1 www-data centreon-engine

At one of our customers we are trying to activate Free IT 100.We got the LKey couple of months ago.When we try to activate we get error “Can’t reach Centreon License Delivery Service”.For a test we tried to generate a new test LKey on your website – but we get error that You are curently upgrading Your internal platform.Are some of your systems not working at this point? If so, when could we expect them to be operational?We are experiencing this issue – both generating a new LKey and registering a customer Free IT 100 Centreon edition for over a 3 weeks at this point.Is there any other way to activate Free IT 100 edition at our customer?How long is the planned duration of your service outage?Kind regards,Danijel.

Est-il possible d’utiliser le magasin d’autorités de certification Windows plutôt que de devoir spécifier un chemin vers un fichier de certificat en dur ?Les autorités de certification étant déjà déployées sur mes serveurs via des GPO, il serait pertinent de pouvoir s’appuyer sur ce mécanisme existant plutôt que de maintenir des fichiers séparés.  Is it possible to use the Windows Certification Authorities store instead of specifying a hard-coded path to a certificate file?Since the certification authorities are already deployed to my servers via Group Policy, it would make sense to leverage this existing mechanism rather than maintaining separate certificate files.

Bonjour,J’ai installé l’agent windows cms version 25.10.8plugin : OS-Windows-Files-Generic-Centreon-Monitoring-Agent-customcentreon detecte la présence du fichier, le test devient rouge.En revanche, si je supprime le fichier , centreon ne detecte rien et me laisse le test en rouge.Je dois soit restarter le service coté agent windows ou soit refaire un export configuration.Stange .Merci 

Hello, Just a note that recently the unattended script on page https://docs.centreon.com/docs/24.10/installation/installation-of-a-poller/unattended-install-poller/ as step 2 for installing 24.10 pollers:curl -L https://download.centreon.com/24.10/unattended.sh --output /tmp/unattended.sh is throwing HTTP 404 and downloading the HTML error page instead.URL: https://download.centreon.com/24.10/unattended.sh In my opinion, it would be better for these pages to either:if this situation is unavoidable, return HTTP 404 status without returning a human readable document, instead of whole HTML to be pulled and executed blindly on other people’s servers, return a script that echoes “sorry we pulled the script for maintenance, try again later”, or joining lines 2 and 3 using && operator to avoid executing the error page.  Thank you.

Superviser la présence d’un fichier windows ne fonctionne pas.Doit-on passer par un script ?Merci

Pour une supervision sur des serveurs windows avec CMA, pourquoi centreon remonte des chiffres en PetraBytes ou ExaBytes lorsque l'occupation du swap augmente alors que la taille qui lui est alloué n'est que de quelques Giga ?Merci d’avance !
