Memory Performance Chart

The Memory chart displays historical statistics on memory utilization for the selected 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

Memory Active

GB

Sum of all active memory metrics for all powered-on VMs and vSphere services (such as COS, vpxa) on a host, as estimated by VMkernel based on recently touched memory pages.

Memory Consumed

GB

Amount of physical memory used on a host, including memory used by the Service Console, VMkernel, vSphere services and total memory consumed by running VMs.

Memory Pressure

Percent

Potential memory demand that is based on total allocated memory for running VMs, memory overhead, effects of memory Transparent Page Sharing and total available memory.

Memory Usage

Percent

Memory usage as percentage of available machine memory.

Memory Swap Rate

Memory Swap Used

B

Amount of memory swapped to disk: sum of memory swapped for all powered on VMs and vSphere services on a host.

Swap In Rate

B/s

Rate at which memory is swapped from disk into host active memory during the current interval.

Swap Out Rate

B/s

Rate at which memory is swapped from host active memory to disk during the current interval.

Memory Management

Memory Balloon

B

Amount of memory allocated by the VM memory control driver (vmmemctl).

Memory Compressed

B

Amount of RAM pages memory compressed by a host instead of swapping to disk.

Memory Overhead

B

Total amount of memory overhead metrics for all powered-on VMs, plus memory overhead of running vSphere services on a host.

Memory Sharing

Memory Shared

GB

Sum of memory shared metrics for all powered-on VMs, and memory consumed by vSphere services on a host.

Memory Shared Common

GB

Amount of memory shared by all powered-on VMs and vSphere services on a host.

Memory Latency

Memory Latency

Percent

Percentage of time a VM is waiting to access swapped or compressed memory.

Virtual Machine

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

Chart View

Counter

Measurement Unit

Description

Memory Usage

Memory Active

GB

Amount of guest physical memory actively used, as estimated by VMkernel based on recently touched memory pages.

Memory Consumed

GB

Amount of guest physical memory consumed by a VM. The value includes the shared and memory that might be reserved but not actually used; overhead memory is not taken into account.

Memory Entitlement

GB

Amount of host physical memory a VM is entitled to, as determined by the ESX(i) scheduler.

Memory Usage

Percent

Memory usage as percentage of configured physical memory for a VM.

Memory Swap Rate

Memory Swapped

B

Amount of guest physical memory swapped out to the VM swap file by the VMkernel. The metrics refers to VMkernel swapping, not to guest OS swapping.

Swap In Rate

B/s

Rate at which memory is swapped from disk into active memory during the current interval.

Swap Out Rate

B/s

Rate at which memory is swapped from active memory to disk during the current interval.

Memory Management

Memory Balloon

MB

Amount of memory allocated by the VM memory control driver (vmmemctl).

Memory Compressed

MB

Amount of RAM pages compressed by a host instead of swapping to disk.

Memory Overhead

MB

Amount of machine memory used by VMkernel to run a VM.

Memory Saved by Zipping

MB

Amount of memory saved by memory zipping.

Memory Sharing

Memory Shared

MB

Amount of guest physical memory that a VM shares with other virtual machines (through VMkernel Transparent Page Sharing and RAM deduplication).

Memory Latency

Memory Latency

Percent

Percentage of time a VM is waiting to access swapped or compressed memory.

For objects that are parent to ESX(i) hosts and VMs, Veeam ONE Monitor displays rollup values.
Charts for folders, clusters, datacenters, vCenter Servers display rollup values for all hosts in the container. Chart for a resource pool displays rollup values for all VMs in the resource pool.
