Built-In Layouts - Hyper-V
The built-in Hyper-V layout can be loaded at any time by selecting it with Layout → BuiltIn → Hyper-V. It covers overall status and processor, memory, disk and network usage for the hypervisor itself and the virtual machines that it hosts. It is divided into 12 frames, with some frames containing multiple panels. Where appropriate, it is possible to drill down from one panel to another that shows more detail. The Hyper-V layout covers a broad range of system information applicable to a Hyper-V host and its virtual machines, but can be modified if required.
Note that it is possible to override the built-in layouts that ship with the product.
Overview
The overview frame shows instantaneous values for current processor, memory, disk and network usage, together with charts showing how these values have changed over time. Also displayed are three indicators covering core system health, the ratio of virtual to physical CPUs and the maximum memory pressure.
The processor, memory, disk and network values are for combined usage across both the host itself and the virtual machines.
The core system health indicator will show a red stop sign if any virtual machine is reporting a critical health issue, a yellow warning triangle if one or more virtual machines currently has 100% or more memory pressure, and a green tick otherwise. The CPU ratio indicator will be red if the ratio of virtual to physical processors is 8 or above, yellow if it is 6 or above, and green otherwise. The memory pressure indicator will be red if any virtual machine is currently exhibiting a memory pressure of 100% or more, yellow if it is 80% or more, and green otherwise
Resource Usage
The resource usage frame splits out processor, memory, disk and network usage by host and virtual machine, with disk and network traffic further split by read and write rates and send and receive activity respectively.
Top Five
The top five frame shows the five virtual machines with the highest processor load and memory pressure and those with the highest levels of disk and network activity. The highest usage is determined by an average over the last 20 minutes.
Processors
The processors frame is divided into three panels. The first shows total processor load for each virtual machine. The second and third show load for each virtual and logical processor, split by the load imposed by the guest operating system and the load from the hypervisor layer.
Memory
The memory frame shows how much of the overall system memory is allocated to each virtual machine and the current memory pressure for each virtual machine.
Storage
The storage frame shows how the virtual machines are using the attached virtual devices. Note that only virtual devices with filenames that end in .vhd or .vhdx are included. The summary panel shows overall data transfer rates for each virtual machine; these are split into read and write activity on the data transfers panel. The I/O operations panel shows the activity in terms of operations per second, rather than data rates, and the queues and latency panel shows the queue length and latency for both the virtual storage devices and the underlying physical storage subsystem.
Network Adapters
The network adapters frame shows how the virtual machines are using the attached network adapters. The summary panel shows overall data transfer rates for each virtual machine; these are split into receive and send activity on the data transfers panel.
Switches
The switches frame shows the data and packet rates, split by receive and send operations, for each virtual switch. Note that this information is for virtual switches configured on the Hyper-V host, and does not represent the physical switches external to the host system.
Live Migration
The live migration frame shows the key metrics for any current live migrations, split into three panels covering in-memory processing, data received by in-bound migrations and the activity of the migration transports respectively. Depending on how a live migration is initiated, not all charts will show activity while a migration is in progress.
Note that the live migration frame will be absent when connected to systems running Windows 2008.
Event Logs
The event logs frame lists Hyper-V-specific entries in the Application event log. The first panel has filters in place to limit the events to those that typically indicate problems, and the second include all events. See Event Logs for information on viewing the details of an individual event and on the interactive filtering that can be applied to the event lists.
Services
The services frame lists Hyper-V-specific installed services, the first panel showing all installed services and two further panels having additional filters in place to limit the lists to active and failed services respectively. A failed service is one that is configured for automatic start-up but that is not currently running. See Services for details on the starting, stopping and restarting services.
Host
The host frame shows performance information for the host itself, rather than the virtual machines running on in. Five panels cover processor, memory, logical and physical disk activity and network traffic.
