Foglight Resource Optimizer 5.7.1 - User Guide (for Hyper-V Environments)

Waste tab

Figure 7. Waste tab
The Waste tab allows you to configure the settings for determining resources wasted in your environment. These include powered-off VMs, checkpoints, and potential zombie VMs:
•
Determine as waste if area: A resource is considered wasted if one of the following settings is met:
•
VM has not been used for more than [x] Days. Defines when a powered-off VM is wasting resources in your environment by not being used.
•
Checkpoint has not been accessed for more than [x] Days. Defines when a checkpoint is wasting resources in your environment by not being accessed.
•
Determine as a potential zombie if area: A VM is considered a zombie VM if the following five settings are met:
•
Time period used for average calculation is [x] Days. Defines when a resource is considered a zombie VM, by looking at the period used for average calculations.
•
Average Resource Utilization—Deviation. Defines when a resource is considered a zombie VM, by looking at the CPU, memory, disk throughput, and network utilization values.
 
* 
TIP: Deviation is the maximum deviation from the average resource utilization that is allowed for a VM considered to be a zombie.
To save any changes made to the Waste settings, click Save at the bottom of the tab.

Excluded tab

The Excluded tab allows you to remove a VM from the list of excluded objects.
For information about how to add a VM to the list of excluded objects, see Excluding objects.
Figure 8. Excluded tab
The Excluded tab includes the following information:
•
On the left side, a navigation tree, that allows you to select the VM component category.
•
On the right side, the list of VMs excluded from the selected VM category.
To remove VMs from the list of Excluded objects, select the check boxes for these VMs and click Remove.
To save any changes made to the Excluded settings, click Save at the bottom of the tab.
The Excluded tab can also be accesses by clicking Show Excluded Items on the Reclaiming Savings bar. For more information, see Viewing excluded objects.

Prices tab

The Prices tab allows you to define the costs used in estimating potential savings through reconfiguration or elimination of waste:
•
Price for each CPU GHz
•
Price for each Memory GB
•
Price for each Storage GB
•
Currency

To save any changes made to the Prices settings, click Save at the bottom of the tab. The new values for prices apply to all hosts in the environment.

Constraints tab

The Constraints tab allows you to set custom thresholds for select objects in the environment. These recommendations are displayed in the Optimizer tab > VM Configuration/ CPU/ Memory/ Storage views > Modify Recommendation column. Use this tab to add, edit, and remove constraints groups.
 
* 
IMPORTANT: A virtual machine may have several partitions. Foglight Resource Optimizer makes recommendations for each partition separately, but the custom constraints can be set only for the entire VM (not for individual partitions). Therefore, the custom constraint for storage are applied to all partitions on the selected VM.
