What health measurements does Dynatrace monitor for ESXi hosts?

The choice of CPU, Memory, and Disk as the health measurements that Dynatrace monitors for ESXi hosts is correct because these metrics are crucial for assessing the overall performance and health of virtualized environments. Monitoring CPU usage allows Dynatrace to evaluate how much processing power is being consumed and whether the resources are sufficient to meet the demands of the workloads running on the ESXi host.

Memory monitoring enables the identification of potential bottlenecks related to resource allocation, ensuring that virtual machines have adequate memory to function efficiently. Disk monitoring is equally important, as it provides insights into disk usage and performance, helping to prevent issues related to storage capacity and I/O performance that could affect the VMs hosted on the ESXi server.

These measurements specifically relate to the infrastructure layer of virtualization, which is essential for maintaining optimal performance and avoiding service disruptions in virtualized environments. Other choices include metrics that, while relevant in different contexts, do not focus specifically on the critical underlying health metrics of ESXi hosts in the same way.
