StorCLI - Check storage script

Ce script permet de surveiller l’état du stockage du système. Il vérifie l’utilisation des espaces disque et peut générer des alertes en cas de dépassement de seuil critique. Ce script est exécuté automatiquement via une tâche cron planifiée (actuellement les lundis et vendredis à 6h00).

Fonctionnement :

  • Analyse des partitions montées
  • Détection des taux d’utilisation élevés
  • Génération d’un rapport (et éventuellement envoi par mail)

Remarques :

  • Nécessite que les outils système (df, awk, mail, etc.) soient disponibles
  • Prévoir des chemins absolus pour une exécution via cron
