This rule monitors for spikes and dramatic drops in network IO for a VirtualCenter.
VMWVirtualCenter
The network usage is no more than 2.2 standard deviations (NumSTDevs) from the mean network usage.
Normal
None
The network usage is more than 2.2 but no more than 2.8 standard deviations from the mean network usage.
Warning
The network usage is more than 2.8 standard deviations from the mean network usage.
Critical
This rule fires an alarm to report that when a virtual machine within the VirtualCenter is requesting CPU cycles from the ESX Server on which it is running, it is not receiving them some percentage of the time. This will impact performance on the virtual machine.
When the virtual machine requests CPU cycles, it is only not receiving them 2 percent or less of the time.
When the virtual machine requests CPU cycles, it is not receiving them greater than 2 percent but no greater than 8 percent of the time.
When the virtual machine requests CPU cycles, it is not receiving them greater than 8 percent but no greater than 12 percent of the time.

This section lists and describes the virtual machine rules.
Rules in this section:
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.
VMWVirtualMachineMemory
The virtual machine is actively using only 75 percent or less of the memory it has been granted by the vmkernal.
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.
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.
The virtual machine is actively using more than 90 percent of the memory it has been granted by the vmkernal.
