VMW Virtual Machine Balloon Memory Deflation

This rule monitors for virtual machines working excessively to reclaim memory.

To better balance memory utilization across hosts in a cluster, you can add more physical resources to a host or you can use VMotion to move a virtual machine from one host to another.

VMW Virtual Machine Balloon Memory Target

This rule monitors the ability of the virtual machine to swap memory locally in order to free it up for reclamation. If the virtual machine is having no trouble swapping memory normally, the balloon (and therefore the balloon target) is not excessively large. If the virtual machine is having trouble swapping memory, the balloon is excessively large.

VMW Virtual Machine Consumed Vs. Granted Memory

This rule compares the amount of memory that is being requested by virtual machines (the application workload) to the amount of memory granted to the virtual machines by the ESX Server.

If the application workload of the ESX Server is requesting an excessive amount of the available memory resources, you must either add memory to the ESX Server or use VMotion to better balance the virtual machines across the servers within the cluster.
