Performance Metrics for Hyper-V

Gather metrics on hypervisor, VMs, processor, network, storage, and more for both your host server and VMs. Monitor and manage your Hyper-V environment and resolve virtualization bottlenecks in minutes. The Hyper-V monitor uses the Site24x7 Windows agent for monitoring. Install the Windows agent and get your Hyper-V servers auto-discovered.

Once the Hyper-V server monitor is successfully added to your Site24x7 account,

View performance metrics for Hyper-V monitors. Log in to Site24x7 and go to Server > Microsoft Hyper-V Server.
Add a Threshold and Availability profile to declare a specific resource as critical or down. Go to Admin > Configuration Profiles > Threshold and Availability (+).
Analyze trends and identify performance issues with exclusive performance reports.
View key metrics in a single glance with the server inventory and health dashboards, or create your own.
Automate the start, stop, and restart of Hyper-V VMs. Learn more.

VM Status View	A representation of all the VMs in the Hyper-V environment. Gives the status of the VM whether up, down, trouble or unknown. Also, the CPU, memory usage and the processor count for each VM is listed under Node Details
Top VM CPU Usage	A bar chart listing from the highest to the lowest VM in the Hyper-V environment, based on CPU usage
Top VM Memory Demand	A bar chart listing from the highest to the lowest VM in the Hyper-V environment, based on memory usage
Memory Details:
Root Partition Total 1G GPA Pages	The number of 1G pages present in the GPA space of the partition
Root Partition Total 2M GPA Pages	The number of 2M pages present in the GPA space of the partition
Root Partition Total Deposited Pages	The number of pages deposited into the partition

VM Details

(For versions 2012 and above)

Parameters	Description
State	Gives the status of the VM whether UP, DOWN, TROUBLE, or UNKNOWN
CPU Usage	The maximum number of threads that it is allowed to operate on physical cores at any given time
Replication Mode	Primary, Replica, TestReplica, and None are the different replication modes

*For Windows versions 2008 and 2008 R2, only the state, health, and CPU usage of the VM will be tabulated.

Get details of each individual VM, its replication, and parent checkpoint details by clicking More.

Parameters	Description
Memory Demand/Memory Assigned	Dynamic Memory adjusts the amount of memory available to a VM, based on changes in memory demand and values that you specify. Memory Demand/Assigned represent the current amount of memory in demand and the memory assigned currently for a particular VM respectively
Replication Details	Replication is the process of replicating a VM in a primary site to a replica VM in a secondary site. This gives the mode, state (Error, FailOverWaitingCompletion, FailedOver, NotApplicable, ReadyForInitialReplication, Replicating, Resynchronizing, ResynchronizeSuspended, Suspended, SyncedReplicationComplete, WaitingForInitialReplication, Disabled) and health (Normal, Warning, Critical, Not Applicable) of the VM. Also, specifies if the VM is in a clustered state or not
Parent Checkpoint Details	Checkpoints provide a faster and easier way to revert the VM to a previous state. The ID, name and type of the parent checkpoint will be shown

Processor

Parameters	Description
Logical Processor Runtime	Graphical view of Guest, Hypervisor, Idletime and Total runtime of the logical processor. It represents the percentage of time spent by the processor in guest code, hypervisor code, idle state and the total (guest and hypervisor code)
Root Virtual Processor Runtime	Graphical view of Guest, Hypervisor and Total runtime of the root virtual processor. It represents the percentage of time spent by the virtual processor in guest code, hypervisor code and the total (guest and hypervisor code)
Root Virtual Processor Intercepts	The rate of hypervisor intercepts messages
Root Virtual Processor Hypercalls	The rate of hypercalls made by guest code on the virtual processor
Root Virtual Processor Instructions	This gives the graphical view of HLT, IO, Emulated, and MWAIT instructions per second. They represent the rate of HLT/IO/emulated/MWAIT instructions per second executed by guest code on the virtual processor
Root Virtual Processor Accesses	This is the graphical representation of MSR and Control Register accesses. The rate of MSR/control register accesses executed by guest code on the virtual processor

VM Configuration:
Parameters	Description
Name	Name of the virtual machine
State	This tells us if the VM is in the Unknown, Running, Turned Off, Paused, Suspended, Starting, Snapshotting, Saving, Stopping, Pausing, or Resuming state
Start/Stop/Restart	This enables the user to start, stop or restart the VM. Only an admin or a super admin can perform this action
