I upgraded my 21.10 platform to the 22.04 the May 23th at 21:40.The last logs available in the table centreon_storage.logs dates from the May 25th at 01:42.No more entry is available since this date.Monitoring and notification still works.No error seems present in the php and centreon broker logs. The partitioning seems to be done without problems.

If i put back the old  10-centreon.conf everything works  fine (but http only).Here a both version of the config file (it might be a stupid mistake but i can’t find it) :Header set X-Frame-Options: "sameorigin"Header always edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure;SameSite=StrictHeader always set Strict-Transport-Security "max-age=31536000; includeSubDomains"ServerSignature OffServerTokens ProdTraceEnable OffDefine base_uri "/centreon"Define install_dir "/usr/share/centreon"ServerTokens Prod<VirtualHost *:80> RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}</VirtualHost><VirtualHost *:443> ################

Hello to all,My company is currently migrating the monitoring of our infrastructure from Nagios to Centreon. We have already migrated a lot of Windows and we are still continuing. We will soon start the Linux. All our Linux servers are in Debian 10/11. For the moment, we have not yet found a Centreon-NRPE agent for Debian machines. I have the impression that the agent has been developed for CentOS or RedHat. Have you ever done monitoring via NRPE on Debian or Ubuntu systems?Thanks in advance for your answers which would be a great help!

Hello, When I apply a downtime on a Centreon host in REST V2 API, I have a 2h time difference.I don't find this time difference when using CLAPI (or REST API V1) The user with whom I generated an API token has a Europe/Paris timezone configured in his profile. It looks very strongly like a timezone problem but I don't see where to fix it, do you know where it could come from? Do you have the same behavior on your Centreon platform? Thanks and regards
