How are host units calculated in Dynatrace?

Host units in Dynatrace are primarily calculated based on the RAM allocation of a host. This metric is crucial as it directly relates to the resource utilization and performance of monitored applications. The concept revolves around ensuring that there is enough memory to handle the workloads that an application may require, thereby impacting the performance and ability to monitor effectively.

Given that RAM allocation serves as an indicator of the computational power and overall capacity of the host, it becomes a foundational aspect for determining host units. This calculation helps in licensing and monitoring scenarios, allowing organizations to understand their usage and needs better.

The other options focus on different aspects of the monitoring environment but do not accurately represent how host units are calculated within Dynatrace. For instance, the number of active processes is important for performance monitoring but does not directly translate to host unit calculations. Similarly, the number of licensed users or performance metrics during peak usage pertain to user experience and operational performance rather than the core calculation of host units based on resource allocation.
