Pour que la fonctionnalité de bac à événement puisse afficher des événements à jour, il faut absolument que ce module soit activé sur un Broker pour écrire les évènements en base.

 Il ne peut y avoir qu'un event-manager-writer par base MongoDB.

• Donc, pour avoir plusieurs modules qui écrivent sur le même serveur MongoDB, il faut les configurer pour écrire dans des bases différentes ( voir le paramètre database ci-dessous ).
• Cependant, il est fortement déconseillé de configurer plusieurs modules sur un même serveur MongoDB, en raison des ressources qu'un module peut requérir ( bande passante disque et occupation disque )

service shinken-arbiter restart

define broker {
    [...]
    modules                   Module 1, Module 2, Module 3, event-manager-writer
    [...]
}
