Settings
Use the Settings menu to define the default optimization settings for your environment. The Settings Dialog box provides information about the following components:
Configuration tab
The Configuration tab provides recommended settings for CPU, memory, and storage optimization.
|
• |
Thresholds. Provides the values of a resource metric that define the Warning and Critical levels (for CPU, memory, and storage). |
|
• |
Recommendation Calculation area. Allows you to define the following parameters for optimizing the CPU, memory, and storage resources in your environment: |
|
• |
Reserve Margin [x]%. This parameter is used for calculating the Evaluation Result, which is needed for making recommendations. The Recommendation Reserve Margin percentage is the percentage above the recommended basis, reserved for unexpected increases in utilization. |
|
• |
Acceptable Variation [x] % [x] MHz, or [x] % [x] MB. This parameter is used for calculating the Evaluation Result, which is needed for making recommendations. The Acceptable Variation percentage is the minimum percentage deviation of the Evaluation Result from the current setting which results in a recommendation. The Acceptable Variation value is the minimum difference between the Evaluation Result and the current setting which results in a recommendation. |
|
• |
Recommended Basis. Use this list to select the “Recommended Basis” to be used for calculating the Evaluation Result. The following options are available: Average Utilization, Maximum Peak Utilization, and Combined Utilization (half of average utilization plus half of maximum peak utilization). |
|
• |
Peak analysis period: [x] minute(s). Peak analysis period used for peaks calculation. “Peak” is the maximum usage of metric during this period. |
|
• |
Threshold for merging peaks: [x]%. If several peaks happened during the peak analysis period, they are treated as a single peak. |
|
• |
Evaluate calculation over this period of time [x] Day(s). Defines the time interval during which the right-sizing calculation is performed. |
|
• |
History Period [x] Day(s). The Change History view displays the changes for the time interval defined here. |
To save any changes made to the Configuration settings, click Save at the bottom of the tab.
Waste tab
The Waste tab allows you to configure the settings for determining resources wasted in your environment. These include powered-off VMs, unused template images, snapshots, 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. |
|
• |
Template has not been used more than [x] Days. Defines when a template image is wasting resources in your environment by not being used. |
|
• |
Snapshot has not been accessed for more than [x] Days. Defines when a snapshot 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. |

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.
The Excluded tab includes the following information:
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.
