VMW Virtual Machine Disk IO

This rule monitors for spikes and dramatic drops in disk IO for a virtual machine.

VMWVirtualMachineHostStorage

Table 64. 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	None

VMW Virtual Machine Logical Drive Estimated Fill Time

This rule determines when the virtual machine logical drive is likely to reach its capacity, based on its present growth rate.

VMWVirtualMachineLogicalDisk

Table 65. Rule Definition
Conditions	State	Action
At the present growth rate, the logical drive will not reach its capacity within 90 days.	Normal	None
At the present growth rate, the logical drive will reach its capacity in 90 days or less.	Warning	None
At the present growth rate, the logical drive will reach its capacity in 30 days or less.	Critical	Send email to VMware administrator
At the present growth rate, the logical drive will reach its capacity in 7 days or less.	Fatal	Send email to VMware administrator

VMW Virtual Machine Logical Drive Availability

This rule monitors disk utilization and fires when the disk utilization reaches 90 percent or greater.

VMWVirtualMachineLogicalDisk

Table 66. Rule Definition
Conditions	State	Action
The disk utilization is less than 90 percent.	Normal	None
The disk utilization is 90 percent or greater, but less than 95 percent.	Warning	None
The disk utilization is 95 percent or greater, but less than 99 percent.	Critical	Send email to VMware administrator
The disk utilization is 99 percent or greater.	Fatal	Send email to VMware administrator

VMW Virtual Machine Memory Swapping

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

VMWVirtualMachineMemory

Table 67. Rule Definition
Conditions	State	Action
The virtual machine has not moved any of its memory from its physical pages to the VMware swap file within the ESX Server.	Normal	None
The virtual machine has moved some of its memory from its physical pages to the VMware swap file within the ESX Server. This may adversely affect the virtual machine’s performance.	Critical	None
The virtual machine is actively using memory that it has moved to the VMware swap file. This will adversely affect the virtual machine’s performance.	Fatal	None
