The Capacity Utilization widget displays a visual summary of the capacity and workload resources used by the objects in your environment.

How the Capacity Utilization Widget Works

Use the Capacity Utilization widget to identify which objects are underutilized, overutilized, and operating at optimum capacity levels.

The Capacity Utilization widget appears with the name Current Object Utilization on the dashboard named Workload Utilization, which is provided with vRealize Operations Manager.

When you point to an object, vRealize Operations Manager displays a popup summary that displays the object name, the capacity used by the object, and the reason that the capacity resource is constrained on the object. To display the analysis details about the capacity on the object so that you can further troubleshoot the problem, click Details. By default the objects are constrained by the most constrained metric.

For example, if the capacity of your cluster is greater than 100% because it is constrained by disk space, click Details to display the Analysis > Capacity Remaining tab and analyze the capacity remaining for the cluster. On this tab, you can determine whether the memory or disk space being consumed on the object is causing the overutilization problem.

When several objects are affected, an object icon displays the number of objects in the utilization summary. The number of objects appears next to the utilization labels.

For example, a host object icon might display 12 to indicate the number of overutilized hosts in your environment. To display the individual affected hosts, point to the host object icon. A list of host machines appears, including the individual host names and links, the percentage of capacity used on each host, and the reason why the capacity is constrained. To further analyze the capacity details for each host, click the host link to display the Analysis > Capacity Remaining tab so that you can further troubleshoot the problem.

When numerous objects are affected, a graph reflects the number of objects in the utilization summary. The number of objects appears next to the utilization labels.

You can use the Capacity Utilization widget to ensure that all of your objects are as close to optimal as possible. The metric calculation displays a value that indicates the margin by which the object is away from optimal usage. The resolution depends on the object type. For a consumer object, such as a virtual machine, the resolution is usually to right-size the object to bring it to optimal. For a provider object, such a cluster, you can determine whether you must add capacity or move your existing workloads to reduce stress in the environment.

You can add the Capacity Utilization widget to one or more custom dashboards and configure it to display data that is important to the dashboard users.

Where You Find the Capacity Utilization Widget

The widget might be included on any of your custom dashboards. In the left pane, click Home to see your configured dashboards.

The data that appears in the widget depends on how you configured it. To configure the widget, click the pencil on the title bar to configure the settings.

Capacity Utilization Widget Options

The Capacity Utilization widget includes toolbar options.

Table 1. Capacity Utilization Toolbar Options

Option

Description

Action

Displays the available actions for a specific object. For example, if you select the host object icon, the Action icon is enabled and displays all the available actions you can carry out. Some of the options are: Power Off VM, Power On VM, and so on . The actions displayed change based on the type of object you select.

The button is dimmed when actions are not available for an object you select.

Constrained by

Sorts the objects in the chart based on a metric you select. For example, if you select CPU Demand, all the objects constrained by CPU demand are displayed in the chart.

You can sort the chart based on options like: CPU, CPU Demand, Memory, Memory Consumed, and vSphere Configuration Limit.

Reset to initial object

Displays the original view of the chart.
