You can set the expected CPU and memory utilization for the host by using the system defined value, which is computed by using historical averages, by defining a global value, or by defining a value at each cluster level. This value is used for calculating the virtual machine cost allocation.
- Log in to the vRealize Automation interface at https://vRealize_Automation_host_name/vcac/org/tenant_URL by using credentials of a tenant administrator.
- Click Business Management.
- Under Infrastructure, click Private Cloud (vSphere).
- Select Operational Analysis (vSphere).
- Click Edit Utilization.
- You can select the data center for which you want to view or edit base rates of CPU and RAM by using the All Data Centers drop-down list.
- Set expected CPU and memory utilization.
You can select the system defined value, which computes the expected CPU and memory utilization by using historical averages. This option is selected by default.
You can set the fixed utilization percentages for the expected CPU and memory utilization percentages in terms of percentage value. If you select this option, the value that you type is applied to the all server clusters.
You can set the expected CPU and memory utilization percentages for each cluster by typing the value in the Expected CPU Utilization % and Expected Memory Utilization % text boxes. Select the option and then set the expected utilization by navigating to the Expected CPU Utilization % and Expected Memory Utilization % column.
- Click Save.
vRealize Business for Cloud uses the value that you have provided to calculate and display the updated base rates of CPU and RAM in terms of cost per gigahertz and cost per gigabytes for the server cluster. vRealize Business for Cloud also updates the unallocated costs for the server cluster.
