Hyper-V counters display the most accurate information for Hyper-V performance monitoring. Use Hyper-V-specific counters in Performance Monitor on a Hyper-V host to monitor resources on this Hyper-V host. Information about memory is displayed similarly if dynamic memory is enabled. However, the applications on each VM are working at 50% of the speed comparing to the first case when only one VM was running (if you open Task Manager or Performance Monitor inside VMs). Inside both virtual machines you see information that the processors of each VM are loaded at 100%. At the same time, you start the second VM on this Hyper-V host that has the same configuration of virtual devices and run the same application. An application that loads four virtual processors at 100% is running on the first VM and consumes all processor resources on the physical Hyper-V host. Four virtual processors are provisioned for the first VM. Imagine that a physical computer running Hyper-V has a processor with four cores, and two VMs are residing on the Hyper-V host. Performance Monitor can provide incorrect information for virtual machines running on a Hyper-V host because standard (normal) counters are not adapted for VM monitoring. It may be also useful to open Resource Monitor on a Hyper-V host ( resmon.exe). The information collected can be displayed as charts, graphs, and diagrams. Run perfmon in run dialog box or find Performance Monitor in the Computer Management window, add needed counters, and monitor statistics in the graphical user interface (GUI).

The perfmon utility is widely used for performance troubleshooting on Windows systems. Use Performance Monitor (perfmon) on a Hyper-V host and the appropriate counters to monitor utilization of a processor, memory, interface, physical disk, and other hardware. Use Performance Monitor on a Hyper-V Host Use Task Manager to monitor running processes, services, and applications, but not to monitor performance inside VMs. This is because the Task Manager doesnвЂ™t identify machines as being virtual and cannot know how resources are provisioned to a VM. Windows Task Manager doesnвЂ™t show real usage of CPU and memory by a virtual machine. However, donвЂ™t use Windows Task Manager to monitor performance inside a VM. Opening Task Manager is a fast and easy method to view performance and resource usage on physical computers running Windows. DonвЂ™t Use Windows Task Manager to Monitor Resources Inside VMs Hyper-V replication monitoring can be also done in SCVMM. Keep in mind that if you use a Hyper-V cluster, you need SCVMM (System Center Virtual Machine Manager), which is a paid solution, to migrate VMs automatically to optimize resource usage of Hyper-V servers and perform load balancing. If you want to automate VM migration across Hyper-V hosts for load balancing, there is basic functionality to do this within a cluster.

Do performance issues exist on one VM or multiple VMs?ДЇortunately, Hyper-V has some free native tools to monitor performance and resource consumption starting from the GUI of a Hyper-V Manager.

Are there enough free hardware resources on a Hyper-V host?.

Are there enough resources allocated to a VM running on a Hyper-V host?.

If you detect low VM performance, use the following questions to narrow down the possible causes: Note that SNMP (Simple Network Management Protocol) has been deprecated for monitoring Hyper-V hosts.

By monitoring Hyper-V performance, you view statistics about resources to help you make decisions on matters like: provisioning more resources on the current Hyper-V host, re-configuring software on a VM, or migrating a VM to another Hyper-V host. Hyper-V resource monitoring allows you to detect bottlenecks, and manage resources to optimize performance. Why Do You Need Hyper-V Performance Monitoring? This blog post covers Hyper-V monitoring tips and native Hyper-V monitoring tools that are available to you for free. Insufficient or excess resources allocated to a VM can lead to VM performance degradation or can affect the performance of other VMs and the entire environment. When using Microsoft Hyper-V, it is important to monitor hardware resources usage by virtual machines and physical Hyper-V servers. The main advantages of hardware virtualization include logical isolation and rational resource usage. By Michael Bose Tips and Tools for Microsoft Hyper-V Monitoring
