Hyper-V Explorer Summary (All Servers) tab

The Hyper-V Explorer Summary (All Servers) tab shows a summary of system resources for all physical servers that currently exist in your integrated infrastructure.

This tab appears in the Hyper-V Explorer when you select the Servers node on the Hyper-V Explorer Topology tab.

Shows the combined percentage of the CPU usage for all servers in the system.

Combined CPU Consumption %. The combined percentage of the CPU utilization used by all servers to execute system code and user programs during the selected time period.

Drill down on:

Combined CPU Consumption %. Displays the Combined CPU Consumption dialog box.
Figure 172. Combined CPU Consumption dialog box

This tabular view lists all servers that exist in your environment.

Server, CPU. The current amount of the CPU speed that is used by the server.
Server, Key. The color used in the Combined CPU Consumption chart to represent the server.
Server, Memory. The current percentage of memory that is used by the server.
Server, NICs. The number of network interface cards used by the server.
Server, Server Name. Server name.
Server, Status. The server status, associated with any alarms raised against it. If no alarms are fired, the status appears as Normal. Otherwise, the status is set to the highest alarm severity (Warning, Critical, or Fatal).
Server, Version. The version number of the Windows OS running on the server.
Virtual Machines, Configured. The number of virtual machines that exist on the server.
Virtual Machines, Running. The number of virtual machines that are running on the server.

Drill down on any server entry. The Hyper-V Environment dashboard appears, showing the server details on the Hyper-V Explorer Summary tab.

The Hyper-V Explorer’s Virtual Environment view displays a high-level overview of your virtual environment. The view has a tile for each type of object in your virtual infrastructure: Clusters, Servers, and Virtual Machines. Each tile shows how many of the corresponding object instances there are in your virtual infrastructure, as well as the count of objects of that type in each of the alarm states (Normal, Warning, Critical, Fatal).

Alarm counts. The total counts of alarms associated with the clusters, servers, or virtual machines, broken down by alarm types (Normal, Warning, Critical, Fatal).
Cluster count. The number of physical servers in your virtual environment.
Server count. The number of physical servers in your virtual environment.
Virtual Machine count. The number of virtual machines in your environment.

Drill down on:

Clusters. Displays the Clusters dwell, showing the names and states of all clusters in your environment.

This tabular view lists all virtual machines that exist in your environment.

Server, Name. The name of the server on which the virtual machine is running.
Server, Status. The status of the server on which the virtual machine is running, associated with any alarms raised against it. If no alarms are fired, the status appears as Normal. Otherwise, the status is set to the highest alarm severity (Warning, Critical, or Fatal).
Virtual Machine, CPU Utilization. The percentage of the virtual machine’s CPU utilization spent on executing system code and user programs.
Virtual Machine, Name. The virtual machine name.
Virtual Machine, Status. The virtual machine status, associated with any alarms raised against it. If no alarms are fired, the status appears as Normal. Otherwise, the status is set to the highest alarm severity (Warning, Critical, or Fatal).
Virtual Machine, Total Memory. The total amount of memory allocated to the virtual machine.

Hyper-V Explorer Storage

This tab only appears when you are exploring individual servers. It displays an organized view of physical drive and logical disk activity. It identifies the physical drives with the highest disk activity, and the logical drives with the lowest capacity. Use this information to fine-tune your configuration, achieve optimal results, and avoid bottlenecks. In addition, this tab lists all physical drives for the selected server, their read and write rates, along with the logical drives, the space used on each drive, data growth patterns, and related estimates.

The appearance of this tab depends on the object or group of object selected. For example, exploring a cluster shows data transfer rates for each disk volume connected to the selected cluster, among other metrics, while exploring a virtual machine reveals the current utilization of disk resources for that virtual machine.

Figure 180. Storage tab

Hyper-V Explorer Storage tab (clusters)

The Hyper-V Explorer Storage tab displays combination of embedded views displaying disk volumes associated with the selected cluster. It identifies the virtual machines that spend the highest amounts of disk resources. Use this tab to find out more about the overall consumption of disk resources for a given cluster. The information provided on this tab can help you prevent potential bottlenecks by reallocating disk resources where they are most needed.

This tab appears in the Hyper-V Explorer when you select a cluster on the Hyper-V Explorer Topology tab.

Figure 181. Storage tab (clusters)

This tab is made up of the following embedded views:

Shows the data transfer rates for each disk volume connected to the selected cluster.

Table 105. Volumes Connected To Cluster

Lists the disk volumes connected to the selected cluster and shows performance metrics associated with each volume.

Allocated. The amount of space allocated to the selected cluster.
Available Space. The amount of space available on the disk volume.
Capacity. The percentage of the disk space that is currently in use.
I/O. The disk volume's current data transfer rate.
Latency. The current latency of the disk volume.
Name. The name of the disk volume. The indicator on the left shows the disk volume’s alarm state: Normal, Warning, Critical, or Fatal.
Time to Full. The estimated amount of time until which the disk volume will become full.
Total Space. The total amount of disk space.
Weekly Growth Rate. The average amount of space by which the amount of data stored on the disk volume grows every week.
Table 106. Volumes Performance: Volume

Shows the amount I/O resources used by the virtual machines associated with the disk volume selected in the Volumes Connected To Cluster view.

I/O Distribution. A pie chart indicating how much the individual virtual machines using the selected disk volume contribute to the use of I/O resources.
