VM information sources provides an automated way to gather information on the Virtual Machine
(VM) inventory on each monitored source (host); the firewall can monitor the VMware
ESXi, vCenter Server, AWS-VPC, Microsoft Azure VNet, and Google Cloud. As virtual
machines (guests) are deployed or moved, the firewall collects a predefined set of
attributes (or metadata elements) as tags; these tags can then be used to define
Dynamic Address Groups (see
Use Dynamic Address Groups in
Policy) and matched against in policy.
