Which of the following is NOT a type of metric that consumes DDUs?

The reasoning behind identifying VMware metrics as not a type of metric that consumes Dynatrace Davis Data Units (DDUs) lies in the nature of how metrics are categorized within Dynatrace. DDUs are a measure used to quantify the data processed or stored in Dynatrace, especially for monitoring services and applications.

Calculated service metrics and calculated log metrics are both derived from performance data and require DDUs for their storage and processing. They essentially summarize or derive insights from raw data, which inherently consumes DDUs as they represent dynamic calculations based on existing data.

Rest API metrics, similarly, are metrics that arise from API calls made to the Dynatrace platform, which also consume DDUs as they involve processing user-defined data points extracted from monitored applications.

On the other hand, VMware metrics pertain to the monitoring of virtual machines and their performance but do not incur additional DDUs in the same way as the other metric types. This lack of DDU consumption for VMware metrics makes them distinct in this context, as they typically represent a more static dataset that is already accounted for in the licensing structure of Dynatrace.
