Ce script créé par mes soins permet de lister l'ensemble des snapshots existants sur le vCenter et d'envoyer le résultat par mail sous la forme d'un rapport.

Fonctionnalités :

Lister l'ensemble des snapshots existants sur le vCenter
Envoyer un rapport par mail uniquement s'il existe au moins un snapshot sur le vCenter afin de limiter les mails

Prérequis :

Avoir les droits administrateur sur la plateforme VMware
Installer la dernière version des VMware PowerCLI

Utilisation :

Compléter les variables suivantes dans le script :
- $vCenter = "vCenterServerName" (Serveur vCenter)
- $MailFrom = "UserName[at]mail.fr" (Adresse mail de l'expéditeur)
- $MailTo = "UserName[at]mail.fr" (Adresse mail du destinataire)
- $MailCc = "UserName[at]mail.fr" (Adresse mail de la personne à mettre en copie)
- $MailSMTPServer = "SMTPServerName" (Serveur SMTP)
