Which two metrics determine Host Memory Health?

The determination of Host Memory Health primarily revolves around the metrics that directly relate to the usage and efficiency of memory resources. Memory used reflects the amount of memory currently in use by applications and the operating system, offering insight into whether the memory resources are adequate for the workload being managed.

Page faults, on the other hand, indicate when a program accesses a page of memory that is not currently mapped to physical memory. High rates of page faults, particularly hard page faults, suggest that the system is struggling to keep the most frequently accessed data in memory, which can lead to performance degradation. Therefore, monitoring both of these metrics provides a clear understanding of the health and performance of memory in a host, allowing for effective capacity planning and troubleshooting.

The other options do not directly relate to memory management or health. For instance, CPU usage and Disk I/O focus on processor performance and data throughput rather than memory status. Session counts and Response time are more related to application performance measurements rather than infrastructure or resource health. Network bandwidth and Connection count similarly pertain to network performance rather than memory usage.
