Pour vérifier le bon fonctionnement, il peut être intéressant de visualiser le dossier /usr/local/centreon-engine/etc. La nouvelle configuration a été appliquée. Nous continuerons bientôt sur l'installation distribuée avec Centreon-Broker.
Il est aussi intéressant de vérifier la communication du broker entre le Central et le satellite.
