Centreon upgrade error

Hello,I recently wanted Migré my Centeron which was in 3.8 in version 21.10 ,I therefore followed to the letter while adjusting certain information related to my environment / infrastructure. So I got to the point where you have to force version editing via the web interface.so I followed and copied the installation directory where it is needed and started.so I found myself faced with an error telling myself that the database already existed. I told myself that he just had trouble recovering and detected that it is a version mount so I put in the url instead of install.php mit upgrade.php and its launched until that I am found on the error"Update-DB-20.04.0-beta.1.sql Line 22: SQLSTATE[42,000]: Syntax error or access violation: 1118 Row size too large.

Gorgoned configuration with multiple centreon-engine instances

Bonjour à tous,Après m’être lancé en vain dans une tentative d’installation de Centreon, en utilisant les packages sources au format tar.gz à cause de le particularité de notre SI (pas d’accès direct à internet et installation dans des dossiers spécifiques)  [→  topic ].Je suis reparti sur une nouvelle installation de la version 21.10 avec les packages au format rpm, toujours dans le même contexte, mais en jouant avec des liens symboliques pour les répertoires spécifiques... Cette fois-ci, l’installation est plus simple & rapide et va arrive sans souci à son terme.Mon infrastructure est installée et opérationnelle: 1 serveur web, 1 serveur BDD, 1 serveur poller. J’essaie aujourd’hui de reproduire ce que nous avons actuellement en production avec une version plus ancienne (19.04):La très grosse majorité de nos checks sont des checks passifs. Notre infrastructure supervise un très grand nombre de serveurs et donc de services. Pour répartir la charge en entrée sur nos pollers, nous av
