VMW Virtual Machine Consumed Vs. Granted Memory

Purpose
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.
Scope
VMWVirtualMachineMemory
 
Table 226. 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

Purpose
This rule monitors for spikes, dramatic drops, and sustained high levels in CPU utilization for a virtual machine.
Scope
VMWVirtualMachineHostCPUs
 
Table 227. 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

VMW Virtual Machine Disk Command Aborts

Purpose
This rule monitors for situations in which a disk command has been aborted because these may be an indication of hardware problems.
Scope
VMWVirtualMachineHostStorage
 
Table 228. Rule Definition
Conditions
State
Action
There are no disk command aborts to report.
Normal
None
A disk command abort has occurred.
Critical
Send email to VMware administrator

VMW Virtual Machine Disk IO

Purpose
This rule monitors for spikes and dramatic drops in disk IO for a virtual machine.
Scope
VMWVirtualMachineHostStorage
 
Table 229. Rule Definition
Conditions
State
Action
The disk usage is no more than 2.2 standard deviations (NumSTDevs) from the mean disk usage.
Normal
None
The disk usage is more than 2.2 but no more than 2.8 standard deviations from the mean disk usage.
Warning
None
The disk usage is more than 2.8 standard deviations from the mean disk usage.
Critical
