Foglight Resource Optimizer 5.8.3 - User Guide (for VMware Environments)

Credentials tab

A credential is a piece of information that an agent instance needs, in order to gain access to the monitored system. Credentials are encrypted and stored in lockboxes. You can manage credentials in Foglight using the Administration > Credentials dashboard. For information about this topic, see the “Controlling System Access with Credentials” section in the Foglight Administration and Configuration Guide.

The Credentials tab allows you to add, edit, and remove credentials groups. This tab is only for the Storage rightsizer.

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.

Scheduled Actions

Recommendations for improvements in resource utilization can be implemented automatically, or scheduled for implementation at a particular time in the future (for example, within a maintenance window).

 
* 
IMPORTANT: Foglight users must have the “Remediation role” to be able to run and automate recommendations. This role can be assigned to a user using the User Management dashboard. For more information about this dashboard, see the “Controlling user access to dashboards” topic in the Foglight Online Help.

Use the Scheduled Actions menu to access the list of operations scheduled to be run at a particular time in the future.

The Scheduled Actions dialog shows the list of operations scheduled to be run at a particular time in the future, and allows you to edit or remove any scheduled actions. To view only the actions specific to Foglight Resource Optimizer, select the “show only Optimizer actions” checkbox. When the checkbox is not selected, the dialog shows all actions scheduled for your virtual environment.

Figure 11. Scheduled Actions dialog box

To edit a scheduled action:
1
In the Scheduled Actions dialog, click the Edit icon at the right end of the action you want to modify.
The Edit Scheduled Action dialog box appears.
2
Modify the report name, add or remove email addresses, and updated the date and time when the action will be executed, as necessary.
3
Click Apply.
The scheduled action is updated in the list.
4
To save the changes, click Save.
The settings are saved and the Scheduled Actions dialog box closes.

The settings are saved and the Scheduled Actions dialog box closes.

Automate

Recommendations for improvements in resource utilization can be implemented automatically, or scheduled for implementation at a particular time in the future (for example, within a maintenance window).

 
* 
IMPORTANT: Foglight users must have the “Remediation role” to be able to run and automate recommendations. This role can be assigned to a user using the User Management dashboard. For more information about this dashboard, see the “Controlling user access to dashboards” topic in the Foglight Online Help.

Use the Automate menu to set the criteria for automatically sending recommendations for improvements. The Create Automate For <Environment Name> dialog box allows you to configure the following settings:

•
Implement the <Resource> recommendations for <Environment Name>. Select the check boxes (where available) for the recommendations that should be implemented automatically.
 
* 
NOTE: Over-provisioning VMs with CPU, memory, or storage resources can be a large source of wasted hardware (and budget). Sometimes over-provisioning can also be a source of performance degradation, if too many virtual CPUs have been allocated and VMs need to compete to each other for host CPU cores.
•
Choose the recommendation schedule that should be run automatically. Click New to add a new schedule to the list of schedules.
•
Type in the name of the report in the Report Name field.
•
Send an email to a list of recipients when the scheduled action is run. Add, edit, or remove email addresses from the list, as necessary.
Figure 12. Create Automate For <Environment Name> dialog box

All the executable recommendations for improvements in resource utilization from the selected tab can be implemented automatically. When you click Automate, these recommendations are scheduled for implementation at a particular time in the future, and the scheduled recommendations appear in the Scheduled Actions dialog.
