Recommendations page in the vSphere Infrastructure view

The Recommendations page in the vSphere Infrastructure view displays a set of recommended actions that can help you resolve capacity-related problems for your vSphere elements, such as cluster or host.

Scenario

Teresa is a vSphere Technology Specialist in an IT organization. She manages and monitors the vSphere infrastructure to ensure that there are sufficient resources (CPU, memory, and storage) to meet the current and future capacity requirements.

Teresa wants to know whether any of the resources are at risk of saturation. She would like to get the following information:

Identify the infrastructure elements that have at least one resource that is saturated or is nearing saturation.
Know the remedial action to be taken.

Alan, an administrator, installs the vSphere views and provides the required permissions to Teresa to access the view. With vSphere views, Teresa can quickly get the information that she wants. The Recommendations page in the vSphere Infrastructure view provides a list of the infrastructure elements that have saturated or are nearing saturation. For every element, the page provides recommended actions that can be taken to resolve any saturation issues that can occur in the future.

To access the page, in the Views tab navigation pane, click Views > Virtualization > vSphere > Infrastructure and in the vSphere Infrastructure page, click the Recommendations tab.

Based on the type of problem in the infrastructure, a recommendation type is defined. For more information about all the recommendation types, and the configurable parameters and thresholds that are used to generate them, see Resolving-capacity-risk-and-efficiency-issues-by-using-recommendations.

Recommendations summary for all vSphere systems

The Recommendations table displays detailed recommendation information for all the vSphere systems. The following table describes each column in detail.

Filtering options

Use the sorting and filtering options on the page to find a specific system. For more information, see Managing-charts-and-tables-in-Views and Filtering-data-displayed-in-Views.

Additionally, you can use the following filtering options on this page.

Recommendations details

To view the recommendation details for an infrastructure element, click the corresponding Efficiency icon (for example: ).
The Recommendations window displays the exact findings along with the recommended actions that you can take to manage the entity.

The following table explains the different fields that you see in the Recommendations window.

Field	Description
System	Name of the entity.
Optimizer findings	Brief description of the issue.
Type	Recommendation type. It is one of the configuration parameters in the optimizer rule that generates this recommendation.
Severity/Efficiency	Efficiency level of the recommendation that is based on the estimated savings per month that you can achieve by implementing the recommended action.
Generated on	Date of the last run of the associated optimizer rule.
Optimizer rule	Name of the associated optimizer rule.
Recommended actions	Suggested actions that you can implement to optimize your costs. For the Cluster over-subscription type, based on the recommended actions, links to detailed pages for over-subscribed clusters and under-subscribed clusters pages are displayed.

Over-subscribed clusters

The Over-subscribed clusters page displays metrics for vSphere clusters that are oversubscribed. Cluster oversubscription is based on resource allocation and not on resource usage. If none of the resources in the cluster are saturated (Forecasted Saturation recommendation), oversubscription may not be a problem. Cluster oversubscription might also be due to overallocation of resources to the VMs in the cluster.

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

For more information about the Days to Saturation and other indicator parameters used for metric computations in this view, see Indicators.

Under-subscribed clusters

The Under-subscribed clusters page displays metrics for vSphere clusters that are undersubscribed. Cluster oversubscription is based on resource allocation and not on resource usage.
