Foglight Resource Optimizer reports

Several report templates are available with Foglight Resource Optimizer, and together they provide a detailed analysis of the changes made in your environment over time.
Each report template uses report parameters to define the content of the report. Use a template’s default report parameters to quickly generate or schedule a report or optionally change the report parameters to customize the report to better meet your requirements.
The following tables contains an alphabetical list of the Foglight Resource Optimizer reports. They also provide a brief description of the report and the report parameters used to define the content. Report parameters marked with an asterisk (*) are required and you must specify this parameter before the report can be generated.

Investigate resource efficiency

In Foglight for Virtualization, Enterprise Edition systems, the Environment Overview dashboard > Investigate tab provides a quick way to investigate the resource efficiency in your environment and to optimize VMs with incorrect resource allocations, as necessary.
Figure 15. Environment Overview > Investigate tab
For Hyper-V® systems, click the Hyper-V tab. The Resource Efficiency pane provides the following information:
•
CPU: Number of VMs with inaccurate CPU allocation. Click the Optimize link to navigate to the Environment Overview > Optimizer Main View dashboard > CPU tab, which provides recommendations for optimizing the CPU for these VMs. For more information, see CPU.
•
Memory: Number of VMs with inn ac urate memory allocation. Click the Optimize link to navigate to the Environment Overview > Optimizer Main View dashboard > Memory tab, which provides recommendations for optimizing the memory for these VMs. For more information, see Memory.
