The SHO Inventory enables you to view the number of undersized and oversized VMs in your Data Center using the CPU and memory utilization. Using undersized VMs for a prolonged time period might lead to reduced application performance. Also, using oversized VMs causes wastage of resources in the enterprise.
SHO provides Right VM Size recommendations that you can use to size the VMs appropriately so that the VMs are no longer underutilized or over utilized. For more information on right VM sizing, see Right VM Size.
The right VM size is recommended based on the type of utilization (Peak, 95th Percentile, or Average) selected on the Thresholds tab of the Configurations View page.
SHO uses a two level analysis to identify whether a VM is undersized or oversized. Each of these levels uses a threshold that you can define by using the Thresholds configuration feature on the user interface.
