Current Capacity Tab

The Current Capacity view displays information about the current capacity of a selected virtual center or datacenter. It includes the following three panes:

•
Planned Changes pane: Lists all valid planned changes before the deployment date, and provides the capability to create/edit/remove one or more planned changes.
•
VirtualCenter/Hosts Overview pane: Provides details about Current Capacity and Constraint, and allows you to select the Datastore information and Slot Size.
•
Clusters/Hosts pane: Consists of two tabs:
•
Clusters: Provides detailed information about clusters that are available in the selected virtual center or datacenter.
•
Hosts: Provides detailed information about hosts that are available in the selected cluster.
To access the Current Capacity view:
1
On the navigation panel, under Dashboards, click Capacity Director.
The Capacity Director dashboard opens.
2
Use the Group selector located at the top of the dashboard to select the virtual environment that you want to monitor.
3
On the Menu bar, click the Current Capacity tab.
The Current Capacity view appears at the bottom of the Capacity Director dashboard.

* 
NOTE: Enabling or disabling the HA policy, which is configured in vCenter®, is only applicable for the Clusters tab in the Current Capacity view. If the HA policy is enabled for a cluster, Foglight Capacity Director calculates the cluster resources and reserve the cluster resources that are required to satisfy the HA policy. A green check mark appears in the HA column when the HA policy is enabled.
NOTE: When performance issues are prompted, click the message to open the Alarm view and check the detailed information.

Planned Changes pane

The Planned Changes pane on the left bottom of the Capacity Director dashboard offers the following menus:

•
Select Target Deployment Date menu: Allows you to select the deployment date until which the information is displayed in the Planned Changes table.
•
Planned Changes table: Includes a list of valid planned changes sorted chronologically up to the deployment date, which unifies the user interface and enables you to observe the result expected after executing planned changes. If you set the value of Automated to Yes when creating a planned change with the Add/Move/Decommission wizard, an icon appears, indicating that the change is planned to be automatically deployed.
To identify the valid planned changes before a target deployment date:

•
Datastore(s) Included: Allows you to select from the drop-down list the datastores that Foglight Capacity Director should use in calculations for future planned changes.
The following options are available: All Datastores (default option) and particular datastores that varies depending on the virtual center/datacenter selected by the group selector.
•
All Datastores: The Slot Size and available slots are calculated based on all available datastores.
•
Particular datastore: The Slot Size and available slots are calculated based on the cluster/host connected to the selected datastore.
