Microsoft Hyper-V Virtual Machines

Introduction:

This section is common to all the editions of IT360, as per the below constraints;

Professional Edition
Enterprise Edition [Applicable to Probes only, and not applicable / relevant to the Central Server, since the configuration of the monitors happens only at the Probe level. However, you may see these discovered monitors from the Central Server]
MSP Edition [Applicable to Probes only, and not applicable / relevant to the Central Server, since the configuration of the monitors happens only at the Probe level. However, you may see these discovered monitors from the Central Server]

Monitored Parameters:

IT360 monitors the virtual machines configured in the Hyper-V server. It gives the ability to manage VMs (Start/Stop/Restart), from the IT360 web client, in case of any performance problems.

In the Servers tab, click on the drop down icon. The drop down list shows the list of Virtualisation-related systems. Click on the relevant Hyper-V VM, from the list.

You would see the following;

The Availability tab lists all the virtual machines, present in the Hyper-V servers, and their availability status. You can also view Availability history of the virtual machines, for the past 24 hours or 30 days.
The Performance tab shows some key performance indicators of the virtual machines, including CPU Utilization, Memory Utilization, Disk I/O Utilization and Network Utilization, along with heat charts for these attributes. This tab also shows the health status and events, for the past 24 hours or 30 days.
The List view displays all the virtual machines, discovered under each Hyper-V server. This view provides an overall idea of the availability and health of all the virtual machines. The list view also enables you to perform Bulk admin configurations. Click on the individual virtual machines listed, to view the detailed VM metrics.
The Top Virtual Machines tab shows graphs for the top CPU consumers, top memory consumers, top disk I/O consumers, and top network consumers of the Hyper-V server. This section enables you to find out which virtual machines are consuming your server resources, and take action accordingly.

To view detailed performance metrics of a Hyper-V VM, click on the corresponding monitor. Below is an explanation of the metrics shown in these tabs;

Parameter	Description
Monitor Information
Name	The name of the virtual machine.
Type	Denotes the type, you are monitoring.
Health	Denotes the health (Clear, Warning, Critical) status of the VM.
GUID	The unique Hyper-V identifier of this virtual machine.
VM State	Specifies the current state of the virtual machine.
Last Polled at	Specifies the time, at which the last poll was performed.
Next Poll at	Specifies the time, at which the next poll is scheduled.
Availability	Shows the overall availability status of the VM for the day. You can also view 7/30 reports and the current availability status of the VM.
CPU Stats
CPU Utilization	The CPU Usage of the VM, in percentage.
VM Details
Number of Virtual Processors	The number of virtual processors, present in the partition. All executions in this child partition happens on Virtual Processors.
Memory Details
Total Memory	The total memory, currently available to the virtual machine, in mega bytes.
Deposited Pages	The number of deposited pages in this partition.
Address Spaces	The number of address spaces in the virtual TLB of the partition.
Virtual TLB Size recommended	The recommended number of pages, to be deposited for the virtual TLB.
Virtual TLB Pages	The number of pages, used by the virtual TLB of this partition.
GPA space modifications per second	The rate of modifications to the GPA space of this partition.
Virtual TLB Flush Entires per second	The rate of flushes of the entire virtual TLB.
Physical Pages Allocated	The number of physical pages, allocated in this partition.
Preferred NUMA Node Index	The preferred NUMA node index, associated with this partition.
Remote Physical Pages	The number of physical pages, not allocated from the preferred NUMA node.
