+# Prometheus
+
+> Prometheus est un logiciel libre de surveillance informatique et générateur d'alertes. Il enregistre des métriques en temps réel dans une base de données de séries temporelles (avec une capacité d'acquisition élevée) en se basant sur le contenu de point d'entrée exposé à l'aide du protocole HTTP.
+>

+
+## 🔧 Configuration
+
+Pour configurer le service il faut ajouter un fichier prometheus.yml décrivant votre configuration. Vous retrouverz toutes les informations sur la page de [documentation officiel](https://prometheus.io/docs/prometheus/latest/configuration/configuration/).
