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.
• Review the status of the VMs based on the action requested.

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 widgets on the page shows a quick summary of overallocated VMs, such as total number of overallocated VMs, total estimated savings that you can achieve by implementing the recommendations, and savings that you can achieve for each provider.

• Your cloud planner can take appropriate actions on VMs by reviewing the suggested recommendations. The cloud planner can decide to ignore the recommendations, commit VMs to implement recommendations manually, or request automatic implementation (for AWS only). For more information, see Administering-the-resource-usage-recommendations.

  Based on the action performed on the VMs, they are displayed under the Recommended, Committed, Action Requested, or Ignored tabs.  

• 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 following recommendation details are displayed:

   • Type of recommendation
   • Name of the virtual machine

   • 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.

     
     

   • Brief description of the issue
   • Efficiency level of the recommendation based on the estimated savings per month that you can achieve by implementing the recommended actions
   • Date when this recommendation is generated on. It is the date of the last run of the associated optimizer rule.
   • Comparison that shows the difference between the current utilization and the utilization after reconfiguring the VM
   • Criteria used for generating the recommendation
   • Recommended actions that you can implement to optimize cost
   • Benefits of implementing the recommendation

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