Clusters view

The Clusters view is a tree view. It lists the clusters that exist in your environment and shows their state.
This view appears in the Quick-View on the left when you select the Clusters tile in the Virtual Environment view.
Figure 46. Clusters view
Selecting the All Clusters node displays overall resource utilization for all clusters in your integrated system and the elements that consume the highest amount of system resources in the Cluster Summary (All Clusters) view on the right. Similarly, selecting a cluster node shows cluster-specific metrics in the Cluster Summary view on the right.

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.
