Foglight for Hyper-V 5.8.2 - User and Reference Guide

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.

Selecting the All Servers node displays overall resource utilization for all servers in your integrated system, and the elements that consume the highest amount of system resources in the Summary - All Servers view on the right. Similarly, selecting a server node shows server-specific metrics in the Server Summary view.

Summary - All Servers view

The Summary - All Servers view displays overall resource utilization information for a group of physical servers and shows the elements that consume the highest amount of system resources.

This view appears in the Quick-View on the left when you select All Servers in the Servers view.
