Release Notes
March 2020
Welcome to Foglight Resource Optimizer
Resolved issues and enhancements
Getting started with Foglight Resource Optimizer
Virtual machines (VMs) are quickly becoming the industry standard in IT infrastructures. IT managers find themselves with hundreds, if not thousands of VMs or physical machine hosts in their infrastructures. VMs can be added quickly, making it necessary to plan for the addition of virtual machines to the physical machines that host them. This can be a challenge for administrators. IT managers lack the required tools to accurately optimize CPU, memory, and network consumption, or project storage requirements. Monitoring virtual machine environments with Foglight™ Resource Optimizer simplifies the optimization process, providing waste-finding and right-sizing functionality for virtualized environments.
These Release Notes cover the resolved issues, known issues, workarounds, and other important information about the 5.8.2 release of the Foglight Resource Optimizer. Review all sections before starting the installation.

|
Defect ID |
Known Issue |
|
VFOG-12427 |
Summary: Foglight Resource Optimizer can reclaim CPU & Memory resources only on one VM at the same time, when the Hot-Add feature was not enabled. Details: The Hot-Add feature only can be enabled in VMware® vSphere® Advanced, Enterprise, and Enterprise Plus versions, but not on the Standard version. Only VM Hardware version 7 or later support the Hot-Add feature. The Guest OS of the VM also needs to support the Hot-Add feature. Workaround: For any Hot-Add disabled VMs, do not reclaim CPU & Memory resources at the same time, otherwise, one of the reclaim actions would fail. |

VFOG-12221 |
When reclaiming selected resources based on the Optimizer recommendations, these entries are removed from the recommendations list while the reclaim operation is in progress. When the reclaim operation completes, these recommendations re-appear on the list for a short time (less than 5 minutes). These recommendations are finally removed from the list only after new data has been retrieved (in next 5 minutes). |
|
VFOG-11968 |
Support resize for hosts using GRUB2 boot loader. |
|
VFOG-11203 |
Remove platforms that have reached end of life and add support to new releases. |

For information about system requirements for this release, see section "Hardware requirements and guidelines" in the System Requirements and Platform Support Guide for the product you have installed.
Before installing Foglight Resource Optimizer, ensure your system meets the following minimum hardware and software requirements:
| Platform, Memory and Hard Disk Space | The platform, memory, and hard disk space requirements for the monitored servers must match the Agent Manager requirements. For complete information, see the System Requirements and Platform Support Guide. |
| Operating System | Foglight Resource Optimizer can be installed on any supported Foglight Management Server or Foglight Evolve configuration. |
This section provides information about problems that you might encounter while monitoring your environment with Foglight Resource Optimizer, and describes the solutions available to troubleshoot these problems.
This section includes the following topics:
Users must evaluate the time a VM needs to shut down for reclaiming resources.
For example, if the evaluation result is 5 minutes, users must:
1. Add
-Dcom.quest.hyperv.timeout.minutes=5 to
the FglAM_HOME\state\default\config\baseline.jvmargs file.
2. Restart the Foglight Agent Manager to load the parameter and use the new value.
With default configuration, the recommendations provided by the Foglight Resource Optimizer for Hyper-V Environments are not displayed on the Federation Master.
Workaround:
1. Add the following line to the FOGLIGHT_HOME\config\server.config file on Federation Master:
server.vm.option0 =
"-Doptimizer.hyperv.vm.life.period.millis=1800000";
2. Save changes, and then restart the Management Server.
Foglight includes a licensing capability that restricts access to those features that are defined in the license. Any Management Server installation requires a license that grants access to server-specific parts of the browser interface and the features associated with them. Foglight cartridges are also license-protected. While some cartridges are covered by the base Foglight license (such as Foglight Agent Manager cartridges and Foglight for Infrastructure), others may require an additional license. Foglight Resource Optimizer is covered by the Foglight Evolve Operate and Flex license and Foglight for Virtualization, Enterprise Edition license.

If you plan to reclaim resources that require a VM shutdown (for example, Change CPU or Memory Allocation, Power Off VM, etc.), and there is no Integration Service on the targeted VM, save all data on that VM before performing the reclaim action.
VMs without Integration Services cannot be shut down successfully. Instead, the VMs are turned off, and all unsaved data is lost.
If you plan to reclaim resources that require a VM shutdown (for example, Change CPU or Memory Allocation, Power Off VM, etc.), and there are no VMware Tools installed on the targeted VM, save all data on that VM before performing the reclaim action.
VMs without VMware Tools cannot be shut down successfully. Instead, the VMs are turned off, and all unsaved data is lost.
