REST API v1 host categories don't work

Hi, I’m trying to add a host into “host categories” in my centreon server using Rest API v1, but it seems to not work properly:The commandcurl --silent --location 'http://centreon.local/centreon/api/index.php?action=authenticate' --header 'centreon-auth-token: some_secret' --header 'Content-Type: application/json' --data '{ "object": "HC", "action": "addmember", "values": "mycategorie;my.host.lan"}'The result:400Bad Request → "Bad parameters"But going to the server and executing the command, it works.centreon -u admin -p 'some_secret' -o HC -a addmember -v "mycategorie;my.host.lan"centreon -u admin -p 'some_secret' -o HC -a getmember -v "mycategorie"id;name2787;my.host.lanI’m missing something?https://docs.centreon.com/docs/api/rest-api-v1/#host-categorieshttps://docs.centreon.com/docs/api/clapi/#addmember-and-setmember

Centreon Database ssl connection

Hi, We have a distributed centreon 22.10.4 platform.We would like to secure the connections between centreon central (client) and it’s database (mariadb server) by using x509 certificates.We’ve already configured the client.cnf file and the server.cnf file by setting the right path and the right certicate. We have this problem : mariadb sslv3 alert certificate unsuported Do you have any idea about it ? Have you ever tried to secure the connection between centreon central and it’s deported db ? We have x509v3 certificates with the right extension TLS Web Server Authentication for the server and TLS Web Client Authentication for the client. Even if the connection works manually with simple certificates without extensions, centreon shows that : “Access denied for user 'user_'@'HOST' (using password: YES).We would also like to know if centreon handle ssl in the core connection with database ? We’ve seen the db.pm file that does not take into account the eventuality of ssl use. Regards.Seri

Centreon is not running.

Hello everyone,I am stuck with my centreon which despite several installations still does not want to start. When I export my configuration, I have no errors but it still remains stopped. So I don't have anything display-wise.I don't really know what to do anymore, because I updated it, restarted it, reinstalled it.If anyone knows what I should be looking for, because the logs don't tell me anything either, I'm interested.Thanks

Weird NMAP Discovery Error

Hi, I’m getting the following error message when trying to do an NMAP discovery - what am I meant to do here?! We trust you have received the usual lecture from the local SystemAdministrator. It usually boils down to these three things:     #1) Respect the privacy of others.    #2) Think before you type.    #3) With great power comes great responsibility. sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper Also, this is a brand new install.

centreon 23.10 web interface, few pages not working

Hello everyone,I installed centreon 23.10, and i’m working on retrieving my services, and getting them to work, but there’s a catch : few of my webpages, crucials ones, aren’t accessibles, while they were before. Hosts configuration wasn’t accessible for quite a while, but recently, i had the service configuration, and the whole status details in the monitoring tab. It seems to work, but doesn’t display any services. And it’s not that the services aren’t working either, as you can see on the resources status screenshot.I think it’s a php error, somewhere, but i’ll need the help of someone who know better than me,  how the inner side of centreon work. thanks for the help !

Wrong plugin name in installation command

Hi there, I am working on two version of centreon :Centreon 22.04 on Debian 11 (Bullseye)Centreon 24.04 on Debian 12 (Bookworm)(I am planning to migrate my old system to the new one.) I have a problem on plugins installation.First, it appears on Centreon 24 while configuring it to monitor my hosts, then I noticed it was the same on Centreon 22.. Web : the plugin seems to be installed, but can not be found in “/usr/lib/centreon/plugins”Terminal : the command lead to an error. Actually, it seems that the command is wronge.g. :centreon-pack-network-hp-standard-snmp = KOcentreon-plugin-network-hp-standard-snmp = OK The first command line is provided by Centreon website when you click on “more info” (“i”) of the plugin you wish install. Centreon, is it me or what happenned ?  Julius

Installing Centreon on a CIS-compliant OS

Hello, I’m trying to install Centreon on my AWS cloud using AMIs `ami-04be5c2c7e9923780` (Oracle Linux 9) or `ami-081241b2722de973f` (Alma Linux 8) but I’m encountering issues during the web installation process.Firstly, we are encountering errors during the Centreon installation, such as "usermod: group centreon-engine does not exist," among others. Additionally, configuration files are not being created:ls -lrt /var/cache/centreon/config/engine/*ls: cannot access '/var/cache/centreon/config/engine/*': No such file or directoryls -lrt /var/cache/centreon/config/broker/*ls: cannot access '/var/cache/centreon/config/broker/*': No such file or directory This seems to be because Centreon does not support operating systems hardened by CIS compliances. The main purpose of my post here is to find out if others have encountered the same issue and if there is a known fix available. Additionally, I would like to inquire if the Centreon team plans to implement support for CIS-compliant OS.With g
