Time period used for average calculation is [x] Days. Defines when a resource is considered a zombie VM, by looking at the period used for average calculations.
•
Average Resource Utilization-Deviation. Defines when a resource is considered a zombie VM, by looking at the CPU, memory, disk throughput, and network utilization values.
* 
TIP: Deviation is the maximum deviation from the average resource utilization that is allowed for a VM considered to be a zombie.
