PowerCli ile Datastore Kullanım Oranı

Merhaba,

PowerCli ile Datastore Kullanım Oranı isimli bu yazımda vCenter Server üzerinde bulunan datastore’larınızı günlük raporlayabilir ve doluluk oranlarını takip edebilirsiniz.

Aşağıdaki script’i Windows task scheduler ‘a tanımlayabilir ve bu script’in günlük/aylık/haftalık çalışmasını sağlayabilirsiniz.

Aşağıdaki script sayesinde vCenter Server üzerinde bulunan datastore’ların kapasite oranlarını ve datastore’ların virtual machine’e göre dağılımını görebilirsiniz.

Bu script ile aşağıdaki verileri çekmiş olursunuz.

• Datastore name
• FreespaceGB
• CapacityGB
• Freespace%
• Provisioned VM’s Size(GB)
• Virtual machine

Ayrıca bu verileri günlük olarak mail attırabilirsiniz. Aşağıdaki script’i kendinize göre düzenlemeniz gerekmektedir.
