Analyzing the idle 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 idle VMs in your infrastructure and the estimated saving that you can achieve by terminating them. For detailed recommendations per idle VM, click <Number> Idle VMs to terminate. The Idle VMs to terminate page opens.

The page provides a quick overview of the number of VMs that are idle and the estimated savings that you can achieve by terminating them. The page also displays details and recommendations per VM or server. By default, the information for the current month is displayed. 

From this page, you can achieve the following goals:

• Determine the number of idle VMs in your multi-cloud infrastructure.
• Determine the total estimated savings that you can achieve by terminating the idle VMs.
• View and compare the idle VMs across the public and on-premises cloud providers.
• Analyze the total estimated savings that you can achieve by terminating the idle VMs.
  
  

To analyze the idle VMs in your multi-cloud infrastructure

Determine the idle 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 idle VMs section on the page that provides the following information:
      • Count of the total idle VMs in your infrastructure 
      • Estimated savings that you can achieve by terminating the detected idle VMs

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

2. Analyze the idle VMs in detail

On the Resource Usage page, click the Idle VMs to terminate link. 

The Idle VMs to terminate page opens. The table on the page lists all the idle VMs and their details such as estimated savings that you can achieve by terminating that VM, number of days the VM was detected to be idle, resource configuration, and resource utilization in percentage. 

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.

2. Review the recommendations

   For the VM that you want to view recommendations for, click the icon.
   The Recommendations window opens that provides the exact findings along with the recommended actions that you can take to manage the idle VM.
   
   
   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

   Use the recommendation details and depending on the cloud provider, terminate the idle VM to reclaim the storage space and achieve the estimated cost savings. For more information about how the recommendation is generated and the parameters and thresholds that you can customize to modify the recommendations, see Idle-VM-recommendation.
