Hyper-V Memory Usage Test

This test reports how much physical memory has been allocated to the VMs on the Hyper-V host. With the help of this test, administrators can proactively detect a potential memory contention on the Hyper-V host caused due to improper resource allocation to the VMs. The detailed diagnosis of this test also sheds light on that VM that could be over-sized with memory.

Target of the test : A Hyper-V server

Agent executing the test : An internal agent

Output of the test : One set of results for the Hyper-V host monitored

Configurable parameters for the test
Parameter Description

Test period

This indicates how often should the test be executed.


Specify the HOST for which this test is to be configured.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Available memory for VMs

Indicates the amount of physical memory that is still unused by the VMs.


A high value is desired for this measure. 

Memory used by VMs

Indicates the percentage of physical memory allocated to the VMs on the host.


Ideally, the value of this measure should be low.

A value close to 100% is indicative of excessive memory allocation to the VMs.

You can use the detailed diagnosis of this measure to identify the VM to which maximum physical memory has been allocated.

Total memory available

Indicates the total physical memory capacity of the Hyper-V host.



Memory allocated to VMs

Indicates the total amount of memory allocated to VMs.


Ideally, the value of this measure should be low.
