Script usage : how to hide credentials

Hello the community !Recently you helped me on the ‘Massive import’ topic, by the usage of a script to execute many changes on one action. I’ve used this solution and it works fine.I would like to improve the last line :/usr/share/centreon/script/delete_device_from_hostgroup.sh <user> <password> <hostgroup> <file>My objective is to hide <password>, for obvious security reasons. I’ve tried to use .bashrc file with an alias, but it didn’t work.Do you have an idea to improve this ?Thanks !

Base de données pleine

Bonjour, J’ai actuellement 4 pollers et un serveur Central et je supervise environ 2000 hôtes et 4500 services.Petite question concernant la base de données Centreon qui me donne du fil à retordre. Le répertoire /var/lib/mysql/centreon_storage occupe beaucoup de place et dedans, j’ai plein de fichiers *.ibd (pour la table data_bin) allant de 100 Mo à 1 Go. Est-ce que je peux supprimer à la main les fichiers .ibd les plus anciens avec un rm pour faire de la place ou est-ce qu’il y a une autre manière de procéder ? Version : 20.10.12 Merci d’avance !

IBM Datapower monitoring - anyone got a script to share

Hi,I have a need to monitor the health and capacity of some IBM Datapower Gateways. Looks like they support an SNMP poll interface.Doesn’t look like Centreon has a plugin for these devices.Wondering if anyone out there in Centreon land has already solved this and has a script they could share?Cheers
