Support de Unicode

Bonjour,Export of objects with non ASCII characters is broken (from the UI as from CLAPI), example : Then the generated file can’t be imported, or if imported, it results in an object with a wrong name. (this is with 22.10.11 but as I saw nothing in the changelog about that I guess 22.10.15 still has this (very long lasting) bug.AFAIK, there isn’t any import/export solution in APIv2.Is this bug will be finally fixed someday ? Is the the APIv2 also has those encoding issues ? If not, is it planned to have an import/export functionality?I’m aware I can use SQL, or coding what’s necessary from the existing APIv2, but I can’t figure why it had never been fixed while some new fancy functionalities are developed. Is it so difficult technically? Or am I the only user who complains about that and considers that the fact to be limited to ASCII nowadays is unacceptable?I‘d really like to know  what the other users think, hence this post.

Status duration wrong?

Hi,After an upgrade from 22.10.11 to 22.10.15 I can see all the status duration for problems that roughly equal the time since I made the upgrade, not the time the status present.Is it something unavoidable, or is it a new bug? I never noticed this before.Also, a more general question: the old page has both “duration” and “hard duration”. Which one is the unique “duration” on the new page ? Why there aren’t both present anymore?

Hi,We use the standard centreon Plugin ‘centreon_nsclient_restapi.pl ‘ (From centreon-plugin-Operatingsystems-Windows-Restapi-20230912-083720.el8.noarch)… to run multiple scripts on our remote servers.One of the script (powershell) reads and reports some log file content …. It is executed on a Windows 2019 serveur (The standard encoding on the powershell is UTF-8). The log file is a standard .txt file: If the logs files contains a line like :“ven. 2023-12-01 10:50:04    ERROR    Export_LyncCtrlDeviations    Nombre d'erreurs à vérifier”The result is : UNKNOWN: Cannot decode json response: malformed UTF-8 character in JSON string, at character offset 191 (before "\x{fffd}0080\x{fffd}...") at /usr/lib/centreon/plugins/centreon_nsclient_restapi.pl line 162. The debug mode shows that It receives the string : ‘à vérifier’, like :      ▒\u0080▒ v▒\u0080\u009Arifier If I just remove the accented characters fron the file…. the plugins works well.“ven. 2023-12-01 10:50:04    ERROR    Export_Lync

Retrieving Host Groups and Associated Hosts via Centreon API

"Hello,I am working on generating KPIs on our Centreon platform (prod and dev) using the Centreon API. My goal is to retrieve the list of host groups with their associated hosts, both enabled and disabled.I have followed the documentation provided here: link to documentation. However, I am facing difficulties. I am working with Centreon 22.04.7.Is it possible to achieve this operation with API v1?

How can i reset my Database

Hello, I recently tried to upgrade my Centreon from CentOS to an AlmaLinux OVF provided on the Centreon website. But without success, after a discussion with my manager we agreed to start again from scratch our centreon because it would be much cleaner and efficient to start again on healthy bases.My question is, do you know a way to start from scratch with an existing Centreon? Some kind of way to erase my database and have a blank one as if I were starting Centreon.I currently have access to my web interface, I use mysql, my almalinux is in version 8.8. Thanks a lot!
