PowerCli ile Günlük VM Performans Raporu

Merhaba,

PowerCli ile Günlük VM Performans Raporu isimli bu yazımda VMware vCenter Server üzerinde bulunan virtual machine’lerin günlük CPU, Memory, Disk ve Network kullanım oranlarını çekebilirsiniz.

Aşağıda belirteceğim script sayesinde günlük kulanım oranlarını çekebilir ve bunları mail ile gönderebilirsiniz. Hatta isterseniz, Windows task scheduler üzerinde tanımlama yapıp günlük düzenli olarak çalışmasını sağlayabilirsiniz.

Bu script ile aşağıdaki verilerin günlük ortalamasını alabilirsiniz.

• CPU
• Memory
• Network
• Disk
• Toplam disk
• Free space

Script’i aşağıda görebilirsiniz, kendinize göre düzenlemeniz gerekmektedir.
