Change History view
The Change History embedded view shows the changes that have been implemented in the environment (during the History Period [x] Day(s) defined in the Configuration tab), the object that was affected, and the result of the operation.
To view the change history of all Optimizer tabs, select the “show all Optimizer history” checkbox. When the checkbox is not selected, the view shows only the change history for the selected Optimizer tab.
The number at the top of the view indicates the total number of changes executed for the selected VM component, during the History Period [x] Day(s) defined in the Configuration tab.
|
Target Name. Virtual machine that was affected by the change. | |||
|
Change. Type of change. These changes may include:
| |||
|
Executed. Date and time when the change was executed. | |||
|
Created By. User who scheduled the change. | |||
|
Description. Operation result: Completed, In progress, or Failed (and an explanation why the job has failed). | |||
Optimizer Actions bar
The Optimizer Actions bar allows you to set the following optimizer actions:
|
• |
|
• |
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 and memory optimization.
|
• |
Thresholds. Provides the values of a resource metric that define the Warning and Critical levels (for CPU and memory). |
|
• |
Recommendation Calculation area. Allows you to define the following parameters for optimizing the CPU and memory 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.
