Foglight Resource Optimizer 5.8 - User Guide (for Hyper-V Environments)

VM Resources

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

The VM Resources view includes the following elements:

This table includes the following information:

Virtual Machine. Name assigned to the VM.

Utilization.

Peak Utilization.

Recommendation.

Modify Recommendation.

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.

N/A

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.

The CPU view includes the following elements:

This table includes the following information:

Virtual Machine. Name assigned to the VM.

Utilization. Amount of processing speed that each virtual machine uses.

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

CPU Recommendations. Recommended amount of CPU that users should add or remove for optimization.

Modify Recommendation. 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.

N/A

The Search for a Virtual Machine 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 its name in the search box. The VMs matching the search criteria are displayed in the Virtual Machines table.

Memory

The Memory category allows you to view utilization rates and peak utilization rates. It provides recommendations for optimizing the Memory for the VM.

The Memory view includes the following elements:

This table includes the following information:

Virtual Machine. Name assigned to the VM.

Utilization. Amount of memory that each virtual machine uses.

Peak Utilization. Highest sustained memory utilization rate for the VM over a 15-minutes period.

Memory Recommendations. Recommended amount of memory that users should add or remove for optimization.

Modify Recommendation. 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.

N/A

The Search for a Virtual Machine 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 its name in the search box. The VMs matching the search criteria are displayed in the Virtual Machines table.

Abandoned VM Images

VMs images can easily get abandoned in large virtual infrastructures. This situation typically occurs when a virtual machine that is no longer needed is removed from inventory instead of being deleted. In this case, large amounts of wasted storage space develop.

The Abandoned VM Images category identifies those abandoned VM images and allows you to reclaim them, if necessary. For additional information about abandoned VM images reported on a federated environment, see Working in a federated environment.

The Abandoned VM Images view includes the following elements:

This table includes the following information:

Unused Image File Name. Name of the abandoned image (for example, image created when the VM was deleted from the environment, or when the disk files detached from the existing VM).

Volumes. Combines the volume name and the relevant cluster name.

Size. Size of the abandoned image.

Last Modified. Date and time when the image file was last modified.

Recommendations. Recommends removing the abandoned image file.

N/A

The Search box located on the top left corner of the table. It allows you to search the environment for a specific abandoned VM image, by entering its name in the search box. The image files matching the search criteria are displayed in the Abandoned VM Images optimization table.
