Hyper-V Memory Usage Test
If one/more VMs on a Hyper-V host are over-sized with physical memory resources, it can result in a serious memory contention that may not only affect the host, but also other VMs on the host. By tracking the physical memory allocation to the VMs on a Hyper-V host, administrators can proactively detect over-allocations and can initiate remedial actions before the problem impacts performance. For this, administrators can use the Hyper-V Memory Usage test. This test monitors the physical memory allocated to the VMs, and points to those VMs that are allocated more resources than required.
Target of the test : A Hyper-V / Hyper-V VDI server
Agent executing the test : An internal agent
Output of the test : One set of results for the Hyper-V host monitored

Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Total memory available |
Indicates the total physical memory capacity of the host. |
MB |
|
Memory allocated to VMs |
Indicates amount of physical memory allocated to VMs. |
MB |
|
Memory used by VMs |
Indicates the percentage of physical memory that is allocated to the VMs on the host. |
Percent |
Ideally, this value should be low. A value close to 100% is indicative of over-allocation of physical memory to the VMs. You can use the detailed diagnosis of this measure to identify which VM has been allocated maximum resources. |
Available memory for VMs |
Indicates the amount of physical memory unused on the host. |
MB |
Ideally, the value of this measure should be high. A low value or a consistent decrease in this value is a cause for concern, as it indicates excessive memory usage by the VMs on the host. |
