No Obsess over host/service options in the Engine configuration menu!

I don’t see the in the 22.10 version:  Configuration > Pollers > Engine configuration > Check Options -- “Post Check” options for obsessing!  Will this still work in the centengine.cfg file?  Is this being deprecated?  When was this removed?Helllllp meeeeee, aaaahhhhhhhhhh!

Hello,After a power outage, Centreon started sending email notifications that the guest is down even when it is up. All services are running on the running center. What should I check? I represent a colleague who is on vacation and I can't get to the cause.On the web interface I see that the hosts are up. The notification goes regularly that they are down

On 22.10.6 Centreon (web) itself gets different check-result than centreon-engine on command-line

Hi there everyone, i have a very strange occurence.I have a check in centreon 22.10.6 which gives me a critical result. When i copy the displayed command from the details-Tab and paste it to the poller with the user centreon-engine i get another result from the check than the one displayed on the frontend. How can that be?Using the supplied CentOS7-ISOs since 21.4 and have subsequently updated since then. RegardsTimo

[LDAP] - Configuration with CLAPI

Hello,We have completely automated the installation and configuration of Centreon with clapi or curl request , but we are encountering a problem.When we configure the ldap settings, we import a file:LDAP;ADD;Name;IPA LDAP;LDAP;SETPARAM;Name;enable;1;LDAP;ADDSERVER;Name;ldap_server1;389;0;1;LDAP;ADDSERVER;Name;ldap_server2;389;0;1;LDAP;SETPARAM;Name;alias;uid;[...]But in 23.04, this way of doing things cannot work, because in clapi, the parameters “ldap_auto_sync” and “ldap_sync_interval” don’t exist.[root@server tmp]# centreon -u admin -p 'password' -i ldap.txtLine 1 : Unknown parameter[root@server tmp]# cat ldap.txtLDAP;SETPARAM;Name;ldap_auto_sync;1;[root@server tmp]# centreon -u admin -p 'password' -o LDAP -a SETPARAM -v "Name;ldap_auto_sync;1"Unknown parameter On the GUI, we can see the option:“Enable LDAP synchronization on login: yes”“LDAP synchronization interval (in hours): 1”But in fact, these options are not enabled because:We have log error in Centreon Central:/var/log/php-f

Error during web installation

HI Centreon community, Today we tried to install a new centreon (23.04). During the web installation, we lost connection.  Now we have a message “Everything is ready ! Your Centreon Platform is about to be upgraded from version to 23.04.8” then  Upgrade to this release requires Centreon >= 2.8.0-beta1. Your current version is . Please upgrade to an intermediate release (ie. 2.8.x) first.  Is it possible to run again the web installation ? If yes, how to proceed ? Many thanks,Maxime
