In VMware Aria Operations , a new global property Cluster Utilization Ceiling Factor is introduced. Using Cluster Utilization Ceiling Factor, you can specify the ceiling value and calculate the base rate for a cluster.

You can use the ceiling factor only if the base rate cost calculation is done using Cluster Actual Utilization method. After you set the ceiling factor value, the Actual Utilization of the cluster is rounded off to the next available multiple of the ceiling value. When ceiling value is 0, Expected Utilization is equal to actual utilization. When ceiling value is 20, it is not considered as special case, actual utilization is rounded off to the next multiple.
Note: The ceiling value range is from 0 to 20. If the number is out of this range, the default value of five is used as the ceiling number.

How to Set the Cluster Base Rate Calculation Method

To change the Cluster Base Rate Calculation method, you must go to Configure > Cost Drivers > Cluster Cost page. Click Change next to the Cluster Base Rate calculation method and select Cluster Actual Utilization.

Where to Find Cluster Utilization Ceiling Factor

To set the ceiling value for a cluster, you must go to Administration > Global Settings > Cost/Price>Cluster Utilization Ceiling Factor. Enter the ceiling value between 0 and 20 and click Save.

To view the change is cost metrics, run the Cost Calculation Status and select a cluster .

If the Actual Utilization of the cluster for CPU is 30 % and Memory is 45%, and the ceiling value specified is 10, then
  • Cluster Expected CPU Utilization (%) = 40
  • Cluster Memory Expected Utilization (%) = 50

Actual Cluster Utilization is rounded off to the ceiling value.

If you set the Cluster Utilization Ceiling Factor to either 0 or 20, then the value of Expected Memory Utilization changes to the next number. For example, if you set the ceiling factor to 0 then, the expected utilization value changes to 1.

Support to Roll up Name Space Cost Metrics

The cost metrics of Point of Delivery (Pod) virtual machines (VMs) has been enhanced to support the following scenarios:
  • Cost metrics of Pod VMs are rolled up to the Name Space and Guest Cluster level.
  • All the cost metrics of VMs, Pods, and guest cluster which are present under Name Space are rolled up to Name Space and Guest Cluster level.
