Server monitoring

A Hyper-V server is a physical component required to begin building a virtual infrastructure. Hyper-V servers provide hypervisor-based architecture for controlling and managing resources for the virtual machines that run on it. Virtual machines running on a Hyper-V server share the server’s resources.
To review data collected about a specific server or all servers, make your selection in the Quick-View.

Servers view

The Servers view is a tree view. It lists the servers that exist in your environment and shows their state.
This view appears in the Quick-View on the left when you select the Servers tile in the Virtual Environment view.
