Resource Pools page in the vSphere Infrastructure view

The Resource Pools page in the vSphere Infrastructure view provides views and reports for resource pools. Resource pools are units of resources that are allocated to business units. Use this page to monitor resource usage by resource pool.

The data displayed in the page provides a complete picture of resource pool memory and CPU usage and contention using specific metrics, and helps answer critical questions related to capacity and memory subsystems, such as:

  • How much CPU is reserved for a particular resource pool?
  • How many VMs in my resource pool are powered ON?
  • How much memory is reserved for a particular resource pool?

To access the page, in the TrueSight console navigation pane, click Capacity Views > Virtualization > vSphere > Infrastructure, and in the vSphere Infrastructure page, click the Resource Pools tab.

The data in the page is categorized based on different subsystems and grouped under separate tabs. Click a tab to view the metrics for that subsystem:

SubsystemDescription
CapacityDisplays consolidated trend and saturation related metrics for two subsystems: CPU and Memory. Also, displays number of powered on VM information.
MemoryDisplays memory related metrics, including ballooning, granted and shared memory.

Metrics per resource pool are displayed in a tabular format.

By default, some columns are hidden. You can show or hide columns using the action menuthat is located next to the table title.

This topic contains the following sections:

Capacity metrics

Capacity metrics are displayed in the Capacity page. The Capacity tab is displayed by default, each time you access the Resource Pools page.

Each row in the table represents a resource pool and displays the following metrics:

To view details for a specific vSphere resource pool

To view the details page for a particular vSphere resource pool, click its (hyper-linked) name under the Resource Pool column. You can use the sorting and filtering options on the page to find a specific resource pool. 

For more information, see Sorting a table in the TrueSight console and Using filtering options in views in the TrueSight console.

The Resource Pool details page displays information under the following sections or panels:

Section or PanelDescription
Summary page

A quick graphical summary of the CPU and memory utilization of the resource pool. Core metrics for the selected entity are displayed as analysis charts, depending on available data. At the bottom of each chart is a link that takes you to the Data Explorer view for the specific resource type, and displays charts and information for a larger set of metrics.

The data displayed in Data Explorer view charts for any resource part of this view category, is based on the time filter that is applied to the primary view in this tab. You can select Advanced time periods (other than default/basic) from the Data Explorer view for the selected resource, to view charts over a different time resolution.

For more information, see Resource Pool page in the vSphere Data Explorer view.

Configuration Details pageConfiguration information about the resource pool.
Parent Resource Pool Page

Details of the selected resource pool's parent resource pool. For more information, see Parent Resource Pool table

Associated VMs pageAll available recommendations for the cluster. For more information, see Recommendations page in the vSphere Infrastructure view.
Tags panelList of tags that are associated with the cluster. You can assign or remove tags by using the Edit Tags option from the Tags action menu.
