Important change on 21.10 package repository

As you probably already know, Centreon 21.10 is not a supported version anymore (more information here).As a consequence, the RPM package repository for this version has been archived: it moved from https://packages.centreon.com/rpm-standard/21.10 to https://archives.centreon.com/standard/21.10.If your platform is still running 21.10 and you need to update it, please update your YUM or DNF repository configuration to handle this change.

Error parsing cfg file : Service already exists

Hello everyone,I'm going from one problem to another and the latest is when I export my configuration.I have a service which, even if I remove it or rename it in the /var/cache/centreon/config/engine1/serviceTemplates.cfg file, comes back every time. And this duplication blocks the export.I've searched the resource.cfg, and I don't see why this service, the PING, is repeated. Is there a “hard” place where it's written to be parsed afterwards?  define service { name PING check_command OS-Linux-SNMP-Tcpcon!100.0,20%!500.0,60% check_period 24x7 max_check_attempts 3 check_interval 10 retry_interval 2 register 1 use local-service}define service { name Balloning memory check_command OS-Linux-SNMP-Traffic-Name!1!10 check_period 24x7 max_check_att

Centreon 24 - gorgone-proxy High CPU usage

Hello everybody,I have installed a Centreon 24.04.2 Central server with several pollers.I use the  ZMQ revese flow from the pollers to the Central.I have enabled TLS encryption (forced to “Yes”) with self made certificates on the Broker configuration for the communications between pollers and the Central (Input on the Central and Output on the poller).Everything is Green on the Poller in the GUI. I can Reload/restart/DoCheck on the poller, All work well.However, I have noticed High CPU (99%) usage for the gorgone-proxy process on the Central.We have and old Centreon 21.04 also with several pollers and have no problem of CPU.Do I have missed something ? Or Did I make something wrong ?Thank you for your answer.Best RegardsPierre

How can I exclude ramfs from the Linux SSH Mountpoint service?

I added the OS-Linux-Mountpoint-SSH-custom service template to my Linux hosts, but some give errors because there are ramfs partitions mounted with the ro flag.To avoid these errors I would like to add the ramfs (next to the squashfs and tmpfs) type to the types to exclude in the critical treshold (which by default is '%{options} !~ /^rw/i && %{type} !~ /tmpfs|squashfs/i').How can I do that? Obviously completely ignoring ramfs would also be an option.

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.
