Analyzing the overallocated VMs in your multi-cloud infrastructure

To access the page, in the navigation pane of the TrueSight console  , select  Cloud Cost Control  and click  Cost Optimization. By default, the Resource Usage page is displayed that provides a section with a summary of the total overallocated VMs in your infrastructure and the estimated saving that you can achieve by resizing them. For detailed recommendations per overallocated VM, click  <Number> Overallocated VMs to resize . The Overallocated VMs to resize page opens that p rovides a quick overview of the number of VMs that are overallocated and the estimated savings that you can achieve by terminating them. The page also displays details and recommendations per VM.  By default, the information for the current month is displayed. 

From this page, you can achieve the following goals:

• Determine the number of overallocated VMs in your multi-cloud infrastructure.
• Determine the best and optimal VM sizes for the overallocated VMs to ensure cost savings.
• Determine the total estimated savings that you can achieve by resizing the overallocated VMs.
• View and compare the overallocated VMs across the public and on-premises cloud providers.
• Analyze the total estimated savings that you can achieve by resizing the overallocated VMs.

To analyze the overallocated VMs in your multi-cloud infrastructure

Determine the overallocated VMs in your infrastructure

1. 1. In the navigation pane of the TrueSight console  , select Cloud Cost Control  and click Cost Optimization. By default, the Resource Usage page is displayed 
   2. Review the overallocated VMs section on the page that provides the following information:
      • Count of the total overallocated VMs in your infrastructure 
      • Estimated savings that you can achieve by resizing the detected overallocated VMs

      • A donut chart that shows how the estimated savings are distributed across the providers.

        

2. Analyze the overallocated VMs in detail

On the Resource Usage page, click the Overallocated VMs link. 

The Overallocated VMs page opens. The table on the page lists all the overallocated VMs and their details such as estimated savings that you can achieve by resizing that VM, recommended instance type with the resized configuration, and current resource configuration and utilization. 



Every recommendation has an Efficiency icon associated with it. The icon indicates the level of efficiency improvement. It is based on the estimated savings (in $) per month that you can achieve by implementing the recommended actions. One of the following icons is displayed:Icon - Efficiency level - high  - medium - low The thresholds for calculating the efficiency level is defined in the associated optimizer rule.

1. 3. Review the recommendation details

   To view the recommendation details, for a VM, click the corresponding Efficiency icon (For example. ).
   
   
   The Recommendations window opens that provides the exact findings along with the recommended actions that you can take to manage the overallocated VM. The following screenshot shows a recommendation with sample data.
   

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

   Field	Description
   System	Name of the virtual machine
   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
   Accuracy indicator	Indicates the level of accuracy or reliability of the resizing recommendation. For more information about how the recommendation is generated, see Overallocated-VM-recommendation. You can click the icon to view its description. The icon can have one of the following values: Value - Accuracy level - Medium  - High  - Very High For more information about each accuracy level, see Accuracy-levels-of-resizing-recommendations-for-overallocated-VMs.

   Resize the instances as suggested in the recommended actions to achieve the estimated savings.
