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.

VMWVirtualMachineMemory

Rule Definition
Conditions	State	Action
The balloon has not been growing excessively and is deflating normally.	Normal	None
The balloon has reached 20 percent of the host's memory over the course of the last 90 minutes and has failed to deflate to less than 5 percent over the last 15 minutes.	Warning	None
The balloon has reached 20 percent of the host's memory over the course of the last 90 minutes and has failed to deflate to less than 12 percent over the last 15 minutes.	Critical	None

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.

VMWVirtualMachineMemory

Table 237. Rule Definition
Conditions	State	Action
The balloon target is 33 percent or less of the virtual machine’s configured memory.	Normal	None
The balloon target is greater than 33 percent but not greater than 50 percent of the virtual machine’s configured memory.	Warning	None
The balloon target is greater than 50 percent of the virtual machine’s configured memory.	Critical	Send email to VMware administrator

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.

VMWVirtualMachineMemory

Table 238. Rule Definition
Conditions	State	Action
The virtual machine is consuming 75 percent or less of the memory it has been granted by the ESX Server.	Normal	None
The virtual machine is consuming more than 75 percent but no more than 83 percent of the memory it has been granted by the ESX Server.	Warning	None
The virtual machine is consuming more than 83 percent but no more than 90 percent of the memory it has been granted by the ESX Server.	Critical	Send email to VMware administrator
The virtual machine is consuming more than 90 percent of the memory it has been granted by the ESX Server.	Fatal	Send email to VMware administrator

VMW Virtual Machine CPU Utilization

This rule monitors for spikes, dramatic drops, and sustained high levels in CPU utilization for a virtual machine.

VMWVirtualMachineHostCPUs

Table 239. Rule Definition
Conditions	State	Action
The CPU utilization is no more than 2.2 standard deviations (NumSTDevs) from the mean CPU utilization and the CPU utilization is at 75 percent or less.	Normal	None
The CPU utilization is more than 2.2 but no more than 2.8 standard deviations from the mean CPU utilization, or the CPU utilization is greater than 75 percent but not greater than 83 percent.	Warning	None
The CPU utilization is more than 2.8 standard deviations from the mean CPU utilization, or the CPU utilization is greater than 83 percent.	Critical	Send email to VMware administrator
