Configuring a Virtual Machine's Memory Usage
Configuring a Virtual Machine's Memory Usage
The Memory page shows how much memory is being used by the virtual machine
and how memory resources are allocated to the virtual machine.
Understanding Performance Values
Understanding Performance Values
The values under Performance are based on the past five minutes. The period of time
these statistics cover can be modified. See Configuring the Statistics Period for the
VMware Management Interface. Performance information displayed includes:
- Used Memory - represents the amount of memory allocated to the virtual machine when it was configured, how much memory has been used recently by the virtual machine and how much memory has been shared between all running virtual machines on the server and within the virtual machine itself.
- Reclaimed Memory - represents how much memory has been reclaimed by ESX Server under heavy loads or when you are overcommitting memory.
- Virtualization Overhead - represents how much extra memory the virtual machine process is using, in addition to the amount of memory allocated to it.
Understanding Resources Values
Understanding Resources Values
The values under Resources indicate a range of system memory to which the virtual
machine is entitled. Resource information displayed includes:
- Minimum - represents the minimum amount of memory that must be available in order to power on the virtual machine.
- Maximum - represents the amount of memory allocated to the virtual machine when it was configured.
- Shares - a value which represents a relative metric for allocating memory to all virtual machines. Symbolic values low, normal, and high are compared to the sum of all shares of all virtual machines on the server and the service console. Share allocation symbolic values can be used to configure their conversion into numeric values.
For more information on share values, refer to the resource management man
pages: cpu, diskbw, and mem.
- Memory Affinity - if displayed, this represents the NUMA nodes on the ESX Server system to which the virtual machine can be bound, when the ESX Server system a NUMA system.
