Memory Performance Chart

The Memory chart displays historical statistics on memory utilization for the selected virtual infrastructure object.

Memory Performance Chart

Host

The following table provides information on predefined views and counters that apply to hosts.

Chart View

Counter

Measurement Unit

Description

Memory Usage

Hyper-V Services Memory Consumed

GB

Amount of memory currently consumed by Hyper-V services.

Hyper-V Services Memory Usage

Percent

Amount of memory resources currently used by Hyper-V services.

Memory Consumed

GB

Amount of physical memory resources used on a host.

Memory Usage

Percent

Memory usage as percentage of available machine memory.

Memory Pressure

Average Pressure

Percent

Amount of memory resources available on a host.

Committed Memory

Committed

GB

Demand for virtual memory. The counter shows how much memory were allocated for processes and to which processes the OS has committed a RAM page frame or a page slot in the pagefile (or both). As the Committed counter grows above the available RAM, paging increases and the amount of the pagefile in use increases as well. At some point, paging activity starts to affect perceived performance significantly.

Memory Swap Faults

Page Faults/sec

Number

Page faults that occur when any process attempts to read from a virtual memory location that is marked as 'not present'. The best counter value is zero.

The counter displays both hard page and soft page faults.

Memory Swap Rate

Page Reads/sec

Number

Lack of memory resources. The counter shows how often the system reads from disk because of hard page faults.

The counter shows the number of read operations, not taking into account the number of pages retrieved in each operation. The counter can reveal different kinds of faults that cause system delays.

Page Writes/sec

Number

Number of attempts taken by running the write command/operation to clear unused items out of memory.

Pages are written to disk only if they change while in physical memory, so they are likely to hold data, not code. The counter shows write operations, not taking into account the number of pages written in each operation.

Pages Input/sec

Number

Rate at which memory pages are read from disk.

Pages Output/sec

Number

Rate at which memory pages are written to disk.

Pages/sec

Number

Sum of Pages Input/sec and Pages Output/sec counters.

The counter indicates how often the system uses a hard drive to store and retrieve memory-associated data.

Virtual Machine

The following table provides information on predefined views and counters that apply to VMs.

Chart View

Counter

Measurement Unit

Description

Memory Usage

Guest Visible Physical Memory

GB

Amount of memory visible to the guest OS running inside a VM.

Physical Memory

GB

Amount of memory currently used by a VM.

Memory Pressure

Demand

B

Amount of memory a VM requires to run all active processes.

The counter represents the total committed memory based on data obtained from other performance counters.

Current Pressure

Percent

Current pressure in a VM.

To calculate the counter, Microsoft Hyper-V analyzes the VM total committed memory and calculates the pressure as the following ratio: the amount of memory the VM wants / the amount of memory the VM has.

For objects that are parent to hosts and VMs, Veeam ONE Monitor displays rollup values.
Charts for folders and clusters display rollup values for all hosts in the container. Chart for a resource displays rollup values for all VMs registered as shared resources.
