Hello everyone I had deployed a machine as a poller and connected it to centreon, then later i exported it to a different network and wanted to attach it to a different centreon server, however the command “/usr/share/centreon/bin/registerServerTopology.sh -u admin -t poller -h 192.168.0.1 -n poller-1’ was run succesfully and I could see the poller in the list when I went to add it, however when It came to the gorgoned file I click to copy the contents and I see the error above, I’m unsure what I’m supposed to do, I deleted the old gorgoned file and restarted the service on both the central and the poller, and redeployed the poller and added it again, still same issue, I’m unsure what I should do, I also deleted the log files and the key files: rm -rf /var/lib/centreon-gorgone/.keysrm -rf /var/log/centreon-gorgone/*

In the Monitoring > Map menu of the Centreon web interface, in 21.10 version, what are the prerequisites for displaying the different MAPs that we create with our heavy client? I can see them, but my colleagues can’t, and I don't know why, since we belong to the same groups so the same rules are applied to us. Do we need to change something at the ACL level ? Is there any parameters on their profile that I need to change ?

Hi, I have a poller with many Oracle databases monitored by Centreon’s plugin centreon_oracle.pl.But I have a lot of trace files in directory “/var/tmp/oradiag_centreon-engine/diag/clients/user_centreon-engine/host_<123456789>_<123>/trace”.This leads my poller to ran out of inodes:Filesystem                                Inodes   IUsed  IFree IUse% Mounted on[...]/dev/mapper/vg0-racine                   1237888 1237888      0  100% /[...] There is a way to avoid that?

I made a manual offline installation on a redhat 9 server of centreon 24.04. After correcting some things, I thnik my installation is not the cleanest but should be working. Instead, everytime I go to the centreon login page I have a big centreon logo, a  You need to enable JavaScript to run this app message and if I check the inspect page and the access logs, I have a 404 error on /centreon/api/latest/platform/installation/status, and I cant find this file anywhere??

Hello,I have different resources named “Traffic” (from an interface) that i want to put on a view, on Centreon MAP 21.10. But when i select “Geometric style”, a green little triangle appears. I want to increase it size, so we can be able to see it when we’ll display the view on a screen, but increasing the size (by stretching the corners) just increase the size of the surface of the icon, and not the size of the triangle properly. Do you have any other solution so we can see it more easily ?

Hello guys,Everytime I try to update to a newer version of Centreon starting from Centreon 24.04.4 to a newer version, the update gets stuck on "Congratulations, you have successfully upgraded to Centreon version 24.04.11”. The page that it’s stuck onWhat I have tried so far:I try to update to version 24.10 after to see if it resolved the problem (which it didn’t )I checked the storage, there is still plenty.I checked that all the services required were at the right version and started. (but I could have missed one)In the installation process I get prompted those lines :chmod: cannot access '/var/cache/centreon/config/engine/*': No such file or directorychmod: cannot access '/var/cache/centreon/config/broker/*': No such file or directorySo i’m wondering if it could be a rights attribution problem.Also when I click the finish button I get prompted for a quarter of a second the following:The error that gets displayedBut it could be unrelated. Do you guys have any ideas about what could b

Hi,(Sorry in advance for my English) I’m trying to link a Remote Server on a Central both behind a firewall. Everything is Working (i can supervise some equipement on the remote network) but the Poller on the Remote is still displayed as “Central” and not running. On the Central side, everything is working and the Remote is displayed as working and updating. Is this an issue on the Remote ? Thank you in advance for your help.

The issue is specifically with PHP v8.2 install.  It appears that for Alma v8 it would use the remi repository, but when the OS is v9 it does not use the remi repository.My operating system is AlmaLinux v9.2 ESU (with Tuxcare).   It appears that the unattended.sh script tries to install php 8.2 (required for 24.10) using the command “dnf module install php:8.2”.I have installed PHP 8.2 from the remi repository outside the unattended.sh script, is there an option to the script to skip the php install during the installation process?I have also posted this on the CloudLinux support site to get their take on it and still waiting on their response. ThanksSteve H.

Bonjour,Depuis quelques jours, je m’intéresse à Centreon pour superviser mon parc informatique.J’ai installé Centreon 24.10.7 sur une VM, puis quelques hôtes et services.Le service « ping_lan » affiche bien que mes éléments supervisés sont bien actifs maisje bute sur comment visualiser l’état des disques constituant un NAS Qnap.Mon service est bien basé sur le modèle « HW-Storage-Qnap-Disk-Global-SNMP-custom », les valeurs de la macrosont celles de base.Le status des ressources est réactif mais je n’ai pas saisi où indiquer à Centreoncomment checker les disques du NAS.merci pour votre aideEric 

I have followed the guide https://docs.centreon.com/docs/migrate/migrate-from-3-4/migration from-3-4 to 24.Just a few error when"Everything is ready !Your Centreon Platform is about to be upgraded from version 2.8.26 to 24.04.6"I had to manually run the SQL statements in the files:/usr/share/centreon/www/install/php/Update-20.04.19.php/usr/share/centreon/www/install/php/Update-20.10.11.php/usr/share/centreon/www/install/php/Update-20.10.12.phpBut when the migration is done, and I try to login, I get:"An error occurred during authentication"   If I check the browser DevTools console (F12), i see “500 Internal Server Error”. BRFredrik

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 ?

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.

Today, we have probes for CPU, Swap and Memory and I'd like to be able to add a duration before considering the alert, whether it's warning or critical.A CPU consumption of over 90% for 3 minutes doesn't require the same analysis as a consumption of over 90% for 1 hour.That's why I'd like to add this waiting time before triggering the alert

Bonjour la communauté,Nous avons effectué une migration de CentOS 7 Centreon version 22.10 vers une distribution Alma 9 Centreon version 24.10.5.Nous avons suivi la procédure Migrer depuis un OS de type EL vers un autre OS de type EL (depuis un Centreon 18.10 ou plus récent) | Centreon Documentation (jusqu’à l’étape 5.8).La migration semble s’être bien déroulée.Cependant, en s’authentifiant sur la page aucun résultat s’affiche. Or, dans la partie Configuration\Hôtes\Hôtes ou Configuration\Services\Services par hôte des éléments y figurent.Dans la partie Collecteurs, le collecteur Central.Nous n’avons pas désinstallé les agents précédemment installés pour la version 22.10 (environnement Windows).Serait-il possible d’avoir une aide ?Merci à toute la communauté.
