Foglight Resource Optimizer 5.8.3 - User Guide (for Hyper-V Environments)

Powered Off VMs

In virtual environments, VMs often get turned off and forgotten.

The Powered Off VMs category identifies virtual machines that have been powered off for an extended period. It is recommended to delete these VMs, since they have been powered off for a long time. Users must manually perform this operation. The operation cannot be reverted, and therefore, it should not be automated.

The Powered Off VMs view includes the following elements:

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.

Checkpoints

Creating a checkpoint in a virtual environment does not create a complete copy of the original VM disk file, rather it only copies the delta between disks. A checkpoint file contains only a change log of the original virtual disk. The Checkpoint category identifies the checkpoints taken in your environment that have not been modified for an extended period, and allows you to reclaim them, if necessary.

The Checkpoints view includes the following elements:

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

Potential Zombie VMs

Zombie VMs are powered-on virtual machines that system administrators may have neglected and that are no longer in use. They are often hard to find in a virtualized infrastructure. It is recommended to power off these zombie VMs.

The Potential Zombie VMs category identifies those VMs by analyzing CPU, memory, network, and disk throughput for consistent usage over an extended period. It allows you to reclaim them, if necessary.

By default, a VM is considered a zombie VM if all of the following conditions are met for every resource:

The Potential Zombie VMs view includes the following elements:

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.

VM Configuration

The VM Configuration category allows you to search for VMs with duplicate VMIDs (bios IDs), and provides recommendations for remediation.

The VM Configuration view includes the following elements:

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 VM configuration, by entering its name in the search box. The configurations matching the search criteria are displayed in the VM Configuration optimization table.
