RHV has comprehensive data warehouse with a stable API.
It provides a system monitoring dashboard in the UI to monitor the system in these different levels.

Red Hat Virtualization includes a deeper integration with Red Hat Satellite that allows the querying of errata information for the RHV-Manager’s operating system and provides a complete view into critical updates for the infrastructure lifecycle management. The release also includes the ability to modify the health status of Host, Storage Domain, or Virtual Machine objects based on external factors such as hardware failure or OS monitoring alerts. Users can quickly perform an impact analysis of their environment in the event an object beyond RHV’s normal visibility is at risk of failure.
