Central server gets updated as not running when initializing a remote

Hello,I'm trying to setup a Centreon infrastructure with a Central server and a Remote one.I’m using these versions:Centreon version 24.10 Running on Debian 12 Remote databasesI'm following the documentation.At the last step from Attach a remote server to a central server - when running:systemctl restart cbd centengineThe processes are restarted on the remote server, the web UI shows the remote as running (green),BUT the central server is set to "not running" (red) at the same time.The processes are still running on the Central server. When restarting the services on the Central serveur, the status is back to "running" (green).I haven't seen anything relevant in the logs to explain this.I can see these queries being run on the mysql server:2025-02-08T19:06:36.349406Z 205 Execute INSERT INTO instances (engine,running,name,pid,instance_id,end_time,start_time,version) VALUES('Centreon Engine',0,'Central',31412,1,1739041596,1739039104,'24.10.3') ON DUPLICATE KEY UPDATE engine='Ce

Migrate remote poller

Hello,I’m in the process to upgrade/mirgrate from 21.04 to 24.10.The “Central” is working and now I’m deploying new “Remote Poller” by following the procedure :Migrate from an EL-type OS to Debian | Centreon DocumentationSo I install a fresh Debian 12 and install the package as indicated here Migrate from an EL-type OS to Debian | Centreon DocumentationHowever the documentation is unclear to me …Once the remote poller installation is OK, I just have to replace the configuration on the central and try to push the configuration ?If its the case, then the conf cannot be pushed.Should we “register the server” ? I suppose no as its already registered.Thanks for your support.

Superviser la capacité utilisée des disques en Go

Bonjour à tous,J’aimerais avoir votre aide concernant la supervision des disques sur Centreon 24.10.5 avec AlmaLinux 9. Actuellement, les informations sur l’utilisation des disques sont affichées en pourcentage, mais j’aimerais savoir s’il est possible de convertir ces valeurs en Giga Octet (Go) pour une lecture plus claire et une meilleure analyse.L’idée serait de pouvoir superviser directement la capacité utilisée en Go plutôt qu’en pourcentage, afin de mieux évaluer l’état des disques et anticiper les risques de saturation. Si vous avez déjà mis en place ce type de configuration ou si vous connaissez une méthode pour effectuer cette conversion dans Centreon, je serais vraiment preneur de vos conseils !Merci d’avance pour votre aide et vos retours. 😊Lenny Vaz

Hello, I need help figuring out how to exclude data from a service.I'd like to hide the "Hole Punch Box" from monitoring the "MarkerSupply-Usage" service.To do this, I was thinking of using the EXTRAOPTIONS --filter command. However, I can't find the right syntax for this to work properly.I've tried a lot of different things, e.g.:--filter '^(?!Hole Box Punch$)'--filter '.*Cart.*'Do you have any ideas, please? Thanks for your help.

vCenter vSphere 8 compatibility with Centreon

Hello guys, has anyone here using vCenter vSphere 8 with Centreon? Our current vCenter will be upgraded to vSphere 8 soon. We want to make sure that Centreon would be able to monitor vCenter (vSphere 8), the ESXs inside it and the VM hosts residing in it. Unfortunately, we will not have test vCenter vSphere 8 to test and check the compatibility of Centreon with it. Appreciate, your feedback on this. Sincerely,Crisanto

Dashboard Autologin View by readonly Contact 23.10

Hello, I was trying to setup an autologin dashboard on my Centreon and i am not able to make the autologin feature to work specifically on the dashboard URL. Context I am running Centreon 23.10.22 on Rocky 9 I followed the autologin documentation Configuring Autologin | Centreon Documentation and created a contact with only readonly permissions on the dashboard. After that i created an autologin token and the whole process allows me to create the following URL https://centreon.local/centreon/home/dashboards/library/2?autologin=1&useralias=autologin_readonly_viewer&token=XXXXXX When using this URL, i am sent back to the login page of the Centreon. That being said, if i use that same token to the home page of the Centreon, i can then login and manually go to the dashboard page (i have the permissions on the dashboard as it is shared to the readonly user). CauseThe reason seem to be a 403 HTTP error on the path /centreon/api/latest/configuration/users/current/parameters I am wonde

Sorting in the new interface

Hi,Why sorting on the information column isn’t available anymore? This is very handy to get a list of services suffering from a same issue type?What’s the point of suppressing a trivial functionality like this?! Is that (not so) new (but still in a beta state!) so bloated or badly written that even with a 100 (!) display limit such a simple task like this isn’t possible in an acceptable time?Is it a user desire to get over simplified UI? Or a guideline from a UI specialist of any kind?Why didn’t I provide feedback on this point sooner? Because the issues with this UI are myriads…Please explain such design choice or let me know what I’m doing wrong.Regards,
