Massive import

Hello the community !I’ve learned how to use CLAPI commands to make a massive import of hosts, withe following line :centreon -u [username] -p [password] -i ImportHost.csvImportHost.csv is created with the following format :HOST;ADD;Device;Alias;IP;Template(s);Poller;HostGroup Now, I’d like to remove massively devices from a hostGroup. The CLAPI is given below :centreon -u [username] -p [password] -o HG -a delmember -v "HostGroup;Device" Do you know the way to create a file with the list of devices to remove from the hostGroup, in order to execute the action with a unique command ?(something like centreon -u [username] -p [password] -i DeviceToRemoveFromTheHostGroup.csv)Thanks,Pierre

Installation problem check_centreon_nrpe

Hello,I would like to monitor several Windows hosts with Centreon. I would like to do this monitoring via an NRPE agent. I followed the "https://docs.centreon.com/21.10/fr/integrations/plugin-packs/procedures/operatingsystems-windows-nsclient-05-nrpe.html" doc.Unfortunately, I'm stuck. Indeed, I can't install the "check_centreon_nrpe" on my Centreon server. I can't install the "centreon-pack-operatingsystems-windows-nsclient-05-nrpe". I have a message that the packages could not be foundMy Centreon was installed via the official ISO and no source modifications were made.Could you help me?Thanks in advance for your answers !

Centreon web interface slow when browser offline

Hi everyone. I have a very strange behavior here…I installed Centreon with database using the ISO (latest). Everythning is up to date and monitoring works.After, I need to change the IP of the poller and move the server from a network to another (which has no internet access).Since that, every time a want to change the page (switch from Host configuration page to Services configuration page for instance), the web sever takes at least up to 7 seconds to print the page.I thought about a Mariadb problem, turn on the slow_query debug, nothing found. Does anyone have an idea about that ?? Thanks a lot !

erreur interne

J’ai installé la version 21.10.15 de centreon et par la suite j’ai procédé à une mise à jour des plugins vu qu’il y avait pas dans la plate forme comme l’indique le tutoriel en ligne. Seulement après l’éxécution de la commande se trouvant dans le tutoriel, j’ai constaté que j’étais passé à la version 21.10.3 et en plus en introduisant mes paramètres de connexion de départ sur le formulaire d’authentification, le système me génère le message “Internal server error”.Que faire SVP?
