What does the dashboard tile labeled "Host Health" display?

The "Host Health" dashboard tile is specifically designed to provide insights into the operating system instances within the monitored infrastructure, along with their respective health status. This includes key metrics such as CPU usage, memory consumption, disk space availability, and other vital resources that indicate the operational state of each host.

Focusing on operating systems allows for effective monitoring of performance and alerting administrators to potential issues before they impact application performance. This helps ensure that the underlying infrastructure maintains a stable environment for applications and services to run successfully.

The other options relate to user sessions, traffic quality, and service request health, which are not the primary focus of the "Host Health" tile, further reinforcing that option B truly reflects its purpose.
