Alma Linux 10.8 Update Breaking Centreon

Being the first of the month is was time for me to run my regular updates for my Centreon VMs. This is running AlmaLinux 8.10 Kernel 4.18.0-553.60.1.e18_10.x86_64 and Centreon Version 24.04.15 after the new update and it has broken all of my monitoring. Execute command failed is the error that I am seeing in the status page. I have rebooted the machine with no change. Some googling came up with making sure SELinux was disabled. Initially it was not, but I did change that, rebooted the system again and still getting the same error.Fortunately this is a VM and I did take a snapshot prior to updating so was able to restore functionality quickly. Did some more research, ran the update again, but still the same result. Anyone else run into the same issue? Or would have any further thoughts on what I should check?

One-click alarm generationNew

Hi,An idea - have a button/menu option (just like submit status for services and hosts) to generate an alarm from the service/host. Sometimes there is a need to create a ticket about problem right away as we already know there is an issue but we dont want to wait until the system first notification time is met (sometimes we need to wait 30min or even more for the ticket to be created, although we know there is already known issue and it takes time to manually create a ticket)So basically option that will ignore the first notification time and generate alarm right away.

Centreon Monitoring Agent

Problème déploiement client CMA

Hi,The view by host is limited to 100 objects per page: Wrong number of servicesIt leads to a wrong number of services for host, as you can see in the image below: Right number of servicesThis is utterly wrong in my opinion.Moreover, I don’t understand why the the number of objects per page is limited to such a low maximum of 100.Is the Javascript which handles the display is so CPU intensive that displaying more objects would be too much for a descent browser?!This is Centreon Web 23.10.16

Issue with API generate-and-reload module returning HTTP 500 instead of 204 on Centreon 24.10.8

Hello,When calling the Centreon API endpoint:/centreon/api/latest/configuration/monitoring-servers/3/generate-and-reload I receive an HTTP 500 Internal Server Error with the following JSON response:{ "code": 500, "message": "There was a consistency error in the exported files - please use the legacy export menu to troubleshoot" } Centreon version: 24.10.8 The same operation works correctly when performed manually through the Centreon web interface. The error only happens via the API. Is this a known issue or bug? Are there any recommended solutions or workarounds to fix this?Thank you!

What user for CLAPI command

I’m facing regular issues with using the CLAPI centreon command.Especially in terms of permissions. I face issues regarding permissions on log files or php files, sometimes it’s files created that are blocking gorgone. I was wondering if there was a clear recommendation in terms of what is required in terms of permissions for the execution of a CLAPI centreon command.Is itas root as apache (i’m running in RHEL 9) as centreon (or other centreon linked user like centreon-engine) as a custom user but with centreon as a secondary group Would someone that faced similar issues please guide me ?Thank you so much
