VMW Virtual Machine Active Vs. Granted Memory

Purpose
This rule compares the amount of physical memory that is actively being used by the virtual machine to the amount of memory granted to the virtual machine by the vmkernal.
If active memory approaches the granted memory value in the virtual machine’s configuration, you should consider increasing the granted memory value.
Scope
VMWVirtualMachineMemory
 
Table 224. Rule Definition
Conditions
State
Action
The virtual machine is actively using only 75 percent or less of the memory it has been granted by the vmkernal.
Normal
None
The virtual machine is actively using more than 75 percent but no more than 85 percent of the memory it has been granted by the vmkernal.
Warning
None
The virtual machine is actively using more than 85 percent but no more than 90 percent of the memory it has been granted by the vmkernal.
Critical
Send email to VMware administrator
The virtual machine is actively using more than 90 percent of the memory it has been granted by the vmkernal.
Fatal

VMW Virtual Machine Balloon Memory Deflation

Purpose
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.
Scope
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

Purpose
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.
Scope
VMWVirtualMachineMemory
 
Table 225. 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
