This rule monitors for virtual machines that have a memory limit that is lower than their memory allocation, which could result in poor performance on the virtual machine.

VMWVirtualMachineMemory

Table 244. Rule Definition

The virtual machine has a memory limit that is higher than its memory allocation.

Normal

None

The virtual machine has a memory limit that is lower than its memory allocation.

Critical

None

VMW Virtual Machine Memory Swapping

This rule monitors for the swapping in and out of virtual machine memory.

VMWVirtualMachineMemory
