+Étape 1 : Installer Apache sur la machine à superviser
+
+Pour vérifier si Apache est déjà installé :
+dpkg -l | grep apache2
+
+
+Si la commande retourne un numéro de version, Apache est déjà installé. Sinon :
+
+Sur Ubuntu/Debian :
+sudo apt update
+sudo apt install apache2 -y
+sudo systemctl enable apache2
+sudo systemctl start apache2
+sudo systemctl status apache2
+
+Étape 2 : Installer le module de métriques pour Prometheus
+
+Prometheus ne peut pas lire directement les métriques Apache. On utilise apache_exporter.
+
+2.1 Télécharger apache_exporter
+
+cd /opt
+sudo wget https://github.com/Lusitaniae/apache_exporter/releases/download/v1.0.10/apache_exporter-1.0.10.linux-amd64.tar.gz
