Merhaba,
PowerCli ile Cluster Utilization isimli bu makalemde sizlere vCenter Server üzerinde bulunan cluster’ınızın kullanım oranını hesaplattırabileceğinzi bir script paylaşacağım. Daha önce kapasite raporu ve snapshot raporu ile ilgili bazı script’ler paylaşmıştım. Bu yazılarıma aşağıdaki linkten ulaşabilirsiniz.
Aşağıdaki script’i çalıştırdığınızda isterseniz SMTP alanlarını doldurarak kendinize mail olarak gelmesini sağlayabilirsiniz.
