Before consuming DDUs, what must occur for metrics bound to specific hosts?

The correct response indicates that before metrics tied to specific hosts can utilize Data Driven Units (DDUs), they must first make use of all available included metrics. This is important because included metrics are typically part of the base functionalities provided at no extra cost, which means that users need to fully leverage these standard metrics before transitioning to a billing model that involves DDUs.

This structure encourages efficient use of resources and ensures that users understand the full capabilities of metrics that come with their existing agreements. The necessity to consume the included metrics first allows organizations to assess their monitoring needs and usage patterns, enabling them to make more informed decisions on whether it is necessary to pay for additional DDUs based on their actual requirements.

In contrast, the other choices do not accurately reflect the process necessary for utilizing metrics bound to specific hosts. For instance, the idea that metrics will automatically consume DDUs undermines the need for deliberate resource management and planning. The notion of them being free of charge could mislead users into thinking they do not need to manage their metrics responsibly. Lastly, while API calls may be a part of interfacing with metrics or data ingestion, they are not a prerequisite for consuming DDUs in the context of host-bound metrics.
