Centreon upgrade

Hi,We are looking at upgrading our Centreon Solution at the moment, but we have run into some problems, so I am hoping someone can help. Firstly let me just say, I am not the most experienced with Linux or Centreon.So What we have is a Redhat Centreon Server, and we did have a Centos Remote Server, this obviously is now obsolete, so we used a script from Github to convert it to Oracle Linux, and this looks to have worked okay. The next bit we were looking at doing was to upgrade Centreon to 24.04, to this end we changed the repo to what we believe is the right one for 24.04baseurl=https://packages.centreon.com/rpm-standard/24.04/el8/stable/$basearch/The problem we are having when we run sudo yum update, it initially looks to go through okay, but then we get the following errors:--> Finished Dependency ResolutionError: Package: perl-FFI-CheckLib-0.31-1.el8.noarch (centreon-plugins-24.04-stab

Centreon: Issue Monitoring a Windows Service with a Specific Template

Hello,I'm currently facing an issue with Centreon while monitoring the services of my Windows virtual machines. When I test the monitoring, Centreon reports that the service is "OK". However, even after stopping the service on my VM, Centreon still shows it as "OK", even though it is actually stopped.How can I fix this issue?Thank you in advance for your help.

Damned licence key!

Hi,I’ve been told licence key were now handled online and I would not have to ask for key anytime. What naive being I had have to beleive in this.In addition I’m quite sure licence was valid before I upgrade from 23.10.18 to 23.10.21.Can someone please look at what the funk could it be made to fix this issue? I can’t upgrade the plugin packs.The fingerprint of the regarded platform is 1c7055ac1152efd834c0f759079ec293c7bc413fef2ea7dc1f9d6b6207626003These licence key problematic is a funky plain in the grass!Cheers.

Hello everyone, I recently viewed that the template check “OS-Linux-Disk-Global-SNMP-custom” has a problem and I don’t know how to resolve it. The server shows the free disk storage but differs from the centreon check and the server (df command). I’m aware that the real number is what is shown in the server site, but why is centreon showing another numbers?ServerIn my server i can see the /data disk usage:$ df -h /data/dev/mapper/01--vg-data 4,4T 3,8T 476G 89% /data$ df -H /data/dev/mapper/01--vg-data 4,9T 4,1T 511G 89% /data$ df /data/dev/mapper/01--vg-data 4695587440 3996106512 498103636 89% /data Centreonbut when I use the check i see this in my /data:  I also used the same script as the service and encounters the same problem: $ /usr/lib/centreon/plugins//centreon_linux_snmp.pl --plugin=os::linux::snmp::plugin --mode=storage --hostname=$server --snmp-version='2c' --snmp-community='public' --storage='\/data|\/srv$|\/tmp$|\/var$|\/boot$|\/$' --name --regexp --displ

Issue with VCenter since last update

Hi,Since the last update (version 20.10.4), I’ve been experiencing issues with my VMware setup. The account field in /etc/centreon/centreon_vmware.json is empty, and when I try to resend the login from the Centreon UI in the "Additional Connector Configurations" section, I get the following error:[parameters.vcenters[0].username] The string is empty, but a non-empty string was expected.This issue occurs on all my vCenter hosts. Do you have a solution? When I recreate a vCenter, it works fine.

How to monitor reboot pending of Linux Server ?

Hi, I’m asking a question : There is a simple method to monitor reboot pending of a Linux Server ? Because there are a few methods that’s I read, but don’t know if it’s the right method to do it :Script “check file exist” NRPE4 ?? (I think there is a service to do that) Create a Systemd service and monitor the service (the worse method) For monitor if the Linux server need a reboot there is a way that I learn ; if the server is waiting for a reboot to applied updates, an empty file will be created at :/var/run/reboot-requiredSo we just need to verify if the file exist or not, no ? So that’s why I’m asking, it is the right way to do that or not ? Sorry for my bad english, i’m french.

Service blocked in passive mode

Stopping centengine, removing the service from the retention.dat file, and then restarting (if there is only one poller).

Log Retention

Hello, using the Log Retention with a value 365 or even 31 the Cronjob /usr/share/centreon/cron/centstorage_purge.php doesn’t clean (all) old comments.I’ve got comments from 2017.  Responsible SQL Query to cleanup:DELETE FROM comments WHERE (deletion_time is not null and deletion_time ' . '< __RETENTION__) OR (expire_time < __RETENTION__ AND expire_time <> 0)Value for __RETENTION__ is the value from the config, in my case 365. The table field expire_time is always 0, so the second part of the query is never matching.The field deletion_time is on many entrys NULL (currently 100174 entrys) and on 3287090 entrys not null.  I’m not sure about the fields deletion_time and expire_time what are they for. But comments from 2017 shouldn’t be there in Year 2025 with retention period of 365 days.  Manually checking the filter:SELECT * FROM centreon_storage.comments WHERE (deletion_time is not null and deletion_time < 1708297200 ) OR (expire_time < 1708297200 AND expi
