This section provides instructions on how to use the Foglight Change Analyzer views to analyze the changes occurred in your environment.

When you install Foglight for Virtualization, Enterprise Edition or Foglight Evolve, the Environment Overview dashboard > Investigate tab provides an overview of changes with the highest impact on your environment. For more information, see Highest Impact Changes.

When you install Foglight Change Analyzer and a Foglight system, the Change Analyzer tab appears in the VMware Environment dashboard. It provides several ways of analyzing the changes made to your virtual infrastructure, and of assessing their impact on your virtual environment.

You begin this process by using the Group Selector, located in the upper left section of the VMware Environment dashboard, to select the virtual environment that you want to monitor. The Foglight Change Analyzer views display the changes made to the selected virtual environment and assess their impact on that virtual environment.
