Idle VMs page in the vSphere Virtual Machines view
The Idle VMs page in the vSphere Virtual Machines view displays the idle and powered off VMs. The information can help you to reclaim unused resources.
To access the page, click Views > Virtualization > vSphere > Virtual Machines in the left navigation pane, and then click the Idle VMs tab on the vSphere Virtual Machines page.
The Idle VMs table shows the top idle VMs based on the following criteria:
- The VM is currently powered off and is powered off for at least two weeks.
- The VM is using less than 5% of its CPU for at least two weeks.
The page also shows how much CPU, memory, and storage is configured and used over the last full month and the current month.
Idle and powered off VMs table
The Idle and powered off VMs table displays metric details for all VMs. Each row in the table corresponds to a VM and displays the following metrics:
Name of the VM.
|Network Name||DNS or network name of the VM.||Last value||HOST_NAME|
Brief description of the VM, taken from the metric annotation.
Name of the host on which the VM resides.
|Last value||Host name retrieved by using relationship ‘uses’ from the VM to the host|
Name of the cluster to which the VM belongs.
|Last value||Cluster name retrieved by using relationship ‘uses’ from the VM to the cluster|
Name of the vCenter for this VM.
|Last value||Retrieved from VIRTUALCENTER_NAME of the parent cluster|
Number of days for which this VM is idle.
Current status of the VM: Powered ON or OFF
Total number of virtual CPUs configured on the VM
|CPU [GHz]||CPU GHz of a single vCPU of a VM||Last value||CPU_MHZ|
CPU Used [GHz]
Total CPU consumed by the VM, measured in Gigahertz
|CPU Utilization [%]||Total CPU utilization of the VM||95th percentile|
|Memory [GB]||Total memory allocated to the VM||95th percentile||TOTAL_REAL_MEM|
|Memory Consumed [GB]||Memory used by the VM, measured in Gigabytes.||95th percentile||MEM_CONSUMED|
|Memory Active [GB]||Memory actively used by the VM||95th percentile||MEM_ACTIVE|
|Memory Util [%]||Total percentage of active memory used by the VM.||95th percentile||((MEM_ACTIVE / TOTAL_REAL_MEM) * 100.0)|
|File System Size [GB]||Amount of file system space that can be reclaimed by removing the idle VM, measured in Gigabytes||Last value||TOTAL_FS_SIZE|
|File System Used [GB]||File system space used by the VM||95th percentile|
|File System Utilization [%]||Total percentage of used file systems||95th percentile||TOTAL_FS_UTIL|
|I/O Rate [MB/s]||95th percentile value of the disk input/output rate measured in megabytes per second.||95th percentile||DISK_TRANSFER_RATE|
|Network Rate [Mbit/s]|
95th percentile value of the network input/output rate measured in megabits per second.
Detailed information about a particular VM
To view the details page for a specific VM, click its name under the VM column. You can use the sorting and filtering options on the page to find a specific cluster.
The VM details page displays information for the selected VM under the following sections or panels:
|Section or Panel||Description|
A quick graphical summary of the CPU and memory utilization, and network bit rate and disk transfer rate for the VM. 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 other time filter options to view charts over a different time resolution
For more information, see Virtual Machine page in the vSphere Data Explorer view.
|Configuration Details page||Configuration information about the cluster.|
|Related Information panel|
Links to detailed pages for thresholds.
All available recommendations for the VM. For more information, see Recommendations page in the vSphere Virtual Machines view.
If the virtual node data is available, the forecasted saturation for memory is computed based on the virtual node memory utilization. Otherwise, it is computed using MEM_ACTIVE of the virtual machine. When using MEM_ACTIVE, the vSphere VM Active Memory increase factor is applied to increase the MEM_ACTIVE metric value. You can configure the value of this vSphere VM Active Memory increase factor. For details, see Configuring and managing thresholds for metrics and indicators.
|Tags panel||List of tags that are associated with the VM. You can assign or remove tags by using the Edit Tags option from the Tags action menu.|
