Précision arithmétique

Hi, This is from Centreon Web 23.10.18. Has it been fixed in 23.10.21 or in a more recent branch? I wouldn’t  say it’s a bug, but a quite worrying design choice still imho.Am I the only one for whom it matters quite a bit?

chmod on poller configuration files

Hi, why is that so? :chmod: cannot access '/var/cache/centreon/config/engine/*': No such file or directorychmod: cannot access '/var/cache/centreon/config/broker/*': No such file or directorywarning: %post(centreon-common-23.10.22-1.el8.noarch) scriptlet failed, exit status 1Error in POSTIN scriptlet in rpm package centreon-common(upgrade from 23.10.21 to 23.10.22)I did this upgrade after a reboot and stopped units centreon,httpd, php-fpm so I guess it is normal I hove no file there, but why does a post-install script is doing that, whatever files would be there or not?Is it an attemp at fixing a possible permission issue? I find this strange but maybe it’s not.Related to ?Have a nice weekend

Server migration: how to migrate online EPP ( 2500 hosts ) licence ?

Hi,I just migrated the configuration and data of my test centreon server (centos 6.7 + centreon 22.10 IT-100) to a new server Alma9+centreon 24.04. Everything went well, including the migration of the IT-100 license. Now, I will do the same with my production server, except that it has a 2500 host EPP license (which was an offline license, but recently became an online license with a token, at the request of centreon). How do I migrate this type of license? (request a temporary license?)

Centreon to supervise my office network

Hello Centreon Community,I’m currently setting up Centreon to supervise my office network and would appreciate some guidance.I have installed Centreon on a virtual machine (VM) running under VMware Workstation on my PC.My network IP range is 10.206.38.10 to 10.206.38.254.  i want to supervise real machines and their actual network usage using this Centreon setup.What is the best method to scan and add all the machines in my network to Centreon?Are there specific plugins or configurations I should use for effective monitoring?Since Centreon is running in a VM, what are the best networking settings to ensure it can reach all machines in my network? (NAT, Bridged, etc.)

Hi,I have a problem since the last Centreon update 23.10.22, I can no longer modify a service or even create new ones, because the notification period disappears as soon as I save.So when I reboot the collector, it says I have not assigned a notification period on the service. I am using AlmaLinux 9.5 and Centreon 23.10.22.

[Issue] Centreon Error: "Attempt to run active check on host with no check command"

Hello everyone,I'm experiencing an issue with Centreon where the following error repeatedly appears in the logs:Error: Attempt to run active check on host 'FARJ-AP-ENS-38' with no check command What I’ve checked so far:The host has a Check Command assigned (base_centreon_ping).Active checks are enabled.Applied the configuration changes and restarted the centengine service.Despite these checks, the error persists, causing high resource usage and forcing me to restart the server periodically.Has anyone encountered this issue before or has any suggestions on how to fix it?Thanks in advance! Note: This log appears every minute, which is significantly impacting system performance.

Delay a service status going critical or warning

Is there a way to set a service check that it delays making the status go critical or warning until it has performed all the retry checks?We are using the VMware vCenter connectors and one check that is performed is to report VMs where VMware Tools is not running. Unfortunately this does not take into account that during a VM start-up or reboot that VMware Tools is correctly not running for a short time - thankfully, the check does take into account if the VM is shut down so they don’t go critical if the VM is switched off. We have 500 VDI workstations which are regularly starting up or being rebooted, and having these all go critical is causing our dashboards to look worse than they really are. They should only be critical if the check fails, for example, 5 times in a row and not immediately.I’ve played with the various retry intervals and delays, but they just affect the notifications sent out, not the actual service status.

Automatique poller configuration

Hello,I want to fully automate the installation and registration of a poller on the central with Ansible.For RPMs or even transcribing the 'registerServerTopology.sh' script, this is no problem.I even managed to generate via a playbook the 'gorgon' configuration of the poller.On the other hand I cannot manage to transcribe the 'poller wizard' module of the interface. I noticed this was using an internal REST API, but I can't find any info on the subject.The objective of this playbook is to install, configure, and declare the poller without administrator intervention (among other things, restarting the gorgon service on the central and the poller)Thank you for your helpPhilippe
