VM Resources

The VM Resources category includes all CPU, memory, and storage recommendations for optimizing a particular VM. You can review them all in one tab, instead of going through the CPU, Memory, and Storage tabs. This option allows you to coordinate the recommendations for that VM and reboot the machine once instead of three times.

For a list of requirements necessary for Foglight Resource Optimizer to successfully resize the CPU on virtual machines, see Requirements for CPU resizing. For a list of requirements necessary for Foglight Resource Optimizer to successfully resize the memory on virtual machines, see Requirements for memory resizing. For a list of requirements necessary for Foglight Resource Optimizer to successfully resize the storage on virtual machines, see Requirements for storage resizing.

The VM Resources view includes the following elements:

•

VM Resources optimization table

Table 1. VM Resources optimization table

Description

This table includes the following information:

Virtual Machine. Name assigned to the VM.

Utilization.

•

CPU: Amount of processing speed that each virtual machine uses.

•

Memory: Amount of memory that each virtual machine uses.

•

Storage: How much storage is being used compared to the total storage available.

Peak Utilization.

•

CPU: Highest sustained CPU utilization rate for the VM over a 15-minutes period.

•

Memory: Highest sustained memory utilization rate for the VM over a 15-minutes period.

•

Storage: n/a

Recommendation.

•

Modify Recommendation.

•

CPU: Recommended modifications for the VM’s CPU. To change the Optimizer’s recommendation, click the link in the cell. In the dialog box that opens, type the new recommended value in the Change CPU Allocation field and click Save, or click Reset to Default to restore the default value.

•

Memory: Recommended modifications for the VM’s memory. To change the Optimizer’s recommendation, click the link in the cell. In the dialog box that opens, type the new recommended value in the Change Memory Allocation (MB/GB) field and click Save, or click Reset to Default to restore the default value.

•

Storage: Recommended modifications for the VM’s storage. To change the Optimizer’s recommendation, click the link in the cell. In the dialog box that opens, type the new recommended value in the Change Storage Allocation (GB) field and click Save, or click Reset to Default to restore the default value.

NOTE: To modify the storage recommendation, users must have administrative privileges. For information about managing optimization credentials, see Credentials tab.

The Search box is located on the top left corner of the table. It allows you to search the environment for a specific virtual machine, by entering the VM name, the disk name, or the partition name in the search box. The VMs matching the search criteria are displayed in the Virtual Machines table.

CPU

The CPU category allows you to view utilization rates and peak utilization rates. It provides recommendations for optimizing the CPU for the VM. For a list of requirements necessary for Foglight Resource Optimizer to successfully resize the CPU on virtual machines, see Requirements for CPU resizing.

Table 4. Storage optimization table
Description	This table includes the following information:
	Virtual Machine. Name assigned to the VM.
	Utilization. How much storage is being used compared to the total storage available.
	Storage Recommendations. Recommended storage size for the VM.
	Modify Recommendation. Recommended modifications for the VM’s storage. NOTE: Storage recommendations for powered-off VMs are displayed, but they cannot be reclaimed, and they are not displayed on the Reclaiming Saving bar until the VM is powered on. To change the Optimizer’s recommendation, click the link in the cell. In the dialog box that opens, type the new recommended value in the Change Storage Allocation (GB) field and click Save, or click Reset to Default to restore the default value.
