What key aspect does the Infrastructure dashboard tile monitor?

The Infrastructure dashboard tile is primarily focused on monitoring the health of hosts within the environment. This includes visualizing metrics such as CPU usage, memory consumption, disk activity, and network performance, which are crucial for assessing the operational state of physical or virtual servers and other infrastructure components. By concentrating on these metrics, users can quickly identify any performance issues or resource shortages that might affect the overall stability and performance of the applications running on those hosts. This allows for proactive management of the infrastructure, ensuring optimal performance and reliability.

In contrast, application performance would be monitored through different metrics and dashboards specifically designed for software services. User behavior analysis focuses on how end-users interact with applications, which is also separate from host-level metrics. Service-level objectives deal with the performance targets for applications, also distinct from the health assessment of infrastructure components. Thus, host health is the correct answer since it is the primary focus of the Infrastructure dashboard tile.
