Capacity Details

You can filter the object types, and modify the settings for those object types so that VMware Aria Operations applies these settings. The data that you expect then appears in the dashboards and views.

How the Capacity Workspace Works

When you turn on and configure the Capacity settings for a policy, you can override the settings for the policy elements that VMware Aria Operations uses to trigger alerts and display data. These types of settings include symptom thresholds based on alerts, situational settings such as committed projects to calculate capacity and time remaining, and other detailed settings.

Policies focus on objects and object groups. When you configure policy settings for your local policy, you must consider the object type and the results that you expect to see in the dashboards and views. If you do not change these settings, your local policy retains the settings that your policy inherited from the base policy that you selected.

Where You Set the Policy Capacity Settings

To set the capacity settings for your policy, from the left menu, click Configure > Policies > Policy Definition, and then click Add to add a policy or select the required policy.

In the right pane, click Edit Policy to edit a policy. In the <policy name> [Edit] workspace, click the Capacity card. The capacity settings for host systems, virtual machines, and other object types that you select appears in the workspace.

You can also edit the capacity settings while working on the objects under the Environment Tab. In the Capacity tab under Environment, click the Foundation Policy drop-down and select Edit Capacity Setting.

Option	Description
Time Remaining Calculations	You can set the risk level for the time that is remaining when the forecasted total need of a metric reaches usable capacity. Conservative. Select this option for production and mission-critical workloads. Aggressive. Select this option for non-critical workloads. Peak focused. Select this option if you want to use only the upper range of the data. The projection will be based on the high utilization points. Conservativeness Strength. You can tune the level of conservativeness from one to five, with level 1 being the least conservative and level 5 being the most conservative. By default, the level of conservativeness is set to three. The upper bound will vary based on the level of conservativeness that you choose. Modifying the level of conservativeness will make the projection bounds narrower or wider. Higher the level, the wider the bounds and more conservative the projections for Time Remaining, Capacity Remaining, and Recommended Size. Note: Rare and momentary peaks may be considered outliers and may not impact the projections even at the most conservative risk level. Conservativeness strength is supported by the Conservative risk level. The Aggressive risk level produces Time Remaining, Capacity Remaining, Recommended Size metrics always based on the mean of the projection. Click the lock icon on the left of each element to override the settings and change the thresholds for your policy.
Business Hours Schedule	Configure business hours as per your time zone, for calculation of capacity analysis and projections. VMware Aria Operations considers the business hours for all objects using the current policy. During non-business hours, VMs could be running other data center activities such as OS upgrades, virus scans, etc after working hours, and hence may not appear to be idle. When you mark business hours schedules, VMware Aria Operations can analyze after hours metrics for inventory, compliance, troubleshooting and other purposes. The reclamation and right sizing analysis and recommendations are based on the business hours and ignore spikes after business hours. Since the business hours schedule are based on policies, different objects can have different business hours. The capacity charts will be based on business hours. Note: You can set business hours schedule for VMs and clusters only. Note: After you specify business hours, the capacity forecast for the object will be based on the business hours and not 24 hours. Click the lock icon on the left of each element to override the settings and change the thresholds for your policy.
Filters	Select the object type by which you want to filter. You can filter by Object Types, Local Changes, and Unsaved Changes.
Capacity Settings	Select an object to view the policy elements and settings for the object type so that you can have VMware Aria Operations analyze the object type. You can view and modify the settings for the following policy elements: Allocation Model Custom Profile Capacity Buffer Click the lock icon on the left of each element to override the settings and change the thresholds for your policy.
Criticality Thersholds	You can view and modify the threshold settings for the following policy elements: Time Remaining Capacity Remaining Workload Click the lock icon on the left of each element to override the settings and change the thresholds for your policy.

Click Save to save the changes.

The local changes made will appear under Policies > Default Policy > Capacity section. You can also view the preview of changes in the Capacity card.
