Centreon 24.10 error after upgrade - Oracle Linux 9

Hi there,I’ve just done the upgrade from Centreon 24.04 to 24.10, everything seemed to be ok until I try to push a new config on centralIt fails on a table missing error.I did not find anything around this issue yetThe only point which alerts me now I have this error, is the “upgrade” process done in web :After the 24.10 upgrade, I had to follow the web upgrade two times, didn’t understand why. The second time, the first line was “generating application cache” (or similar), and the second was "upgrading centreon 24.10.2 to”  (right part empty) Can someone help me on this ?Thanks

Licensing, Online vs. Offline

Hi,I stumbled on the following instruction reading the documentation for the Postgres Connector: I don’t understand.Does online license and offline license have to be understood as, respectively, “SaaS” and “on premise”? I wouldn’t say so, but ?Else, if it’s about the way the license validity is checked, then why the nature of this verification would change the way a Connector Pack has to be installed? Do any other non-intuitive things like this are already present or are to be awaited in future releases?Do you have a list of what « online licensing »  implies for the way Centreon behaves? I remember I’ve been told back then it was introduced, that it’s a matter of checking the licence validity, and only that. I’m afraid I’ve been lied to about the real purpose of this functionality. Can someone explain me what means this part of the documentation?

It hosts the 2 centreon DBs and 2 mediawiki DBs.In the Centreon doc it is written that you must use version 1.31 of mediawiki.And it is written in the mediawki doc that it is compatible with MariaDB 10.3.0+.I get this error when I click on the notes_url in the resources screen:Warning: Trying to access array offset on value of type null in /usr/share/centreon/www/class/centreon-knowledge/wikiApi.class.php on line 98Is this related to the different versions installed?Sincerely

[Plugin EATON SNMP] Nouvelle MIB

Hi,When I use the "hardware::pdu::eaton::snmp::plugin" plugin with the "environment" mode I get errors on the return :  It turns out that the temperature probes which are added to the PDU no longer have the same OIDs. OIDs requested by the plugin : OIDs from the new MIB EATON : (.1.3.6.1.4.1.534.6.8)  I can also see that this request has already been made several times on the centreon-plugins github :https://github.com/centreon/centreon-plugins/issues/3222https://github.com/centreon/centreon-plugins/issues/2888 If it was only necessary to change the OID I could have made the modification but in this case it is also necessary to review the mapping because the return of these new OIDs is different and requires adaptation. Could you please modify this plugin to be able to check new PDU ? Do you need me to provide any other information ? Thanks for your help.Kind Regards.
